Crest Ridge Ecological Reserve Area
 |
Crestridge Ecological Reserve is a 3000 acre parcel of land between El Cajon and Alpine. It is bordered by Interstate 8 on the north and west and the community of Crest on the south and east. This area is jointly managed by the Endangered Habitats Conservancy and the California Department of Fish and Game which in most places in of California would mean mountain bikers would be shutout. This is not the case out here as the Earth Discovery Institute which is under contract to do the actual management of this place seems to get the bigger picture that responsible recreational use and conservation can coexist and be mutually beneficial. This place has seen a lot of volunteer hours from mountain bikers to help not only create new trails but to repair some long-standing damage from agriculture and motorized vehicle recreation. There is a lot of climbing to do out here if you are looking to get any miles at all and there are plenty of fire roads. There are also some nice single racks as well. For those of you familiar with Daley Ranch this is somewhat similar but there are more single tracks out here. While the predominant amount of trails I describe here are on the reserve proper there are some trails that are not. Additionally some of the trails here are in the "social" category. The one thing that is exceptionally lacking (as of 2014) about the reserve its virtual absence of trail signs. This pretty much puts each rider in a position to make up their own mind. In this review I'm going to discuss not only the official trails but some the unofficial ones as well. I'm assuming that in the future some trail signs will go up and I am quite certain that trail changes will continue to occur. If you see a sign, please obey it, if you see a trail on my map that looks to have been blocked off, it was probably done as part of the overall plan that mountain bikers are actually involved in. The "basic" loop out here will get about 16 miles with about 2,500 feet of climbing. It is very easy to feel like all directions are uphill out in this area and this place can get exceptionally hot during the summer. There is water at the visitor center and their is a gas station less than a block away from the Park and Ride trail head. You should also be aware that the reserve does not allow night riding in this area. |
| DIRECTIONS: There are quite a few trail head./access point into this area. I am going to just discuss a few. |

| Ride Notes: |
  From the Park and Ride Trail head (Waypoint CR-TH02) cross Camino Canada and proceed on East County Drive for 1/4th of a mile. The trail goes off to right directly across from 8448 East County Drive shortly past a multi-house mail box (CR-001). You are not in the ecological reserve at this point. The single track through here switchbacks and climbs its way up the hill. After 0.22 miles you will come to the junction of another singletrack (CR-002). If you switch back to the left (uphill) you will continue continue climbing up to the ridge line. I prefer to continue straight and in the downhill direction at this junction to take a trail I colloquially called some form of "Wally-World". |
    |
| From this junction the Wally-World trail will twist back and forth as it undulates along the hillside around the shopping center. When you are directly behind Walmart (CR-004) the singletrack comes out at the end of service road and then bends back towards the hillside to your left. From here the trail continues its twisting and undulating action until it connects up with the main fireroad (CR-005) that goes up the hillside to the west of the shopping center. This fireroad is Valleyview Truck Trail. |
  From there you will climb along the fire road for 3/4th of mile until you come to the junction with another fireroad (CR-007) going off to your right and uphill toward some power line towers. Valleyview Truck Trail continues on straight while a singletrack goes off to your left. You will be taking the singletrack off to your left at the end of the return trip so take note of it. Take a right here and grunt your way up the hill for 1/4th of a mile where you will see an singletrack going off to your left. The trail you are going to take goes up to the saddle between the two hills off to your left/east. You will also notice that there is a steep rutted looking singletrack coming down from the peak of the hill to the south of the saddle (CR04-2). This is not a legal trail within the system but it also not marked. It is really rutted and quite frankly not worth poaching. So stay to your left at the fork just after you head east on the singletrack at CR-03 to stay on the saddle singletrack. |
      |
  This is a nice singletrack that has mixture of high scrub brush, grass and trees as it goes up to the saddle. Once at the saddle the trail turns sharply uphill for final push to come out on another old fireroad at CR-04. At this point you can continue east or you can get in an out-and-back climb up to the peak of that south side hill. There are some really nice views of downtown, Point Loma and the Pacific Ocean to be seen there on clear days from the peak at CR-04-2. The trail up to the peak from the east is legal but continuing on to the west from the peak back to CR-03 is not. I personally think the descent going back to the east is more interesting. |
      |
  Continuing eastward from CR-04 you quickly descend down along an old fireroad into the top of a valley. Your first junction is with a fireroad going off to your right (CR-05). The main fireroad continues eastward. (Toward the houses across the valley) The main route is straight ahead to the next fireroad junction on your left (CR-10). If you choose to make a right at this first junction (CR-05) there are some trails down in this area. The fireroad makes a sharp left just a little south of where it start (CR-06). There is a trail/really old fireroad coming in from the south here as well. This is an illegal trail that is predominately used by equestrians as their on private access into the reserve. It is rideable for a while before it get all chewed up from the combination of bad soil, steep grades and hoof damage. Don't bother investigating this trail unless you like slogging your bike through deep sand on steep grades. |
  The other trails between CR-06, 07, 08 and 09 are worth a pedal through before make your way back to the main fireroad that goes down through the valley at CR-10. Note that these trails are not on the public map, but they clearly appear authorized. I'm told that the reserve management has new maps and signage on the to-do list. Use your best judgment in this area as you work your way back over to the the fireroad and find the fireroad that heads north and down into the valley. Now is a good time to grab some visual bearings. To your east is north-south ridge line with a water tower on the top (CR-46) with a paved road coming down from it. There is singletrack that has seen better days come coming down from that paved road down into the valley ahead of you. It is legal and on the map but needs some loving. In its current condition it is best ride it from the water tower down. At the bottom of the valley is a fireroad that works is way rough east-west to to the north end of the ridge line That fireroad at the bottom is the Valleyview Truck that connects all the way back to Walmart as well as some of your future trail junctions on this ride to the east. |
  Descending on the fire road from CR-10 can be a little zippy. After 1/4th of a mile you come to a junction of another trail (CR-11). either way will work but if you take the right-hand fork it will lead you over to the junction of the trail that goes to the water tower (CR-12). Note the old fireroad trail between CR-12 and CR-14 is not on the map but it sees plenty of usage. Not matter which fork you take the trail will bring you out of onto the Valleyview Truck Trail (CR-15) where you will hang a right and go uphill for 1/4th of a mile where the fireroad tops out (CR-16) with a singletrack heading off to the right. You can stay on the fireroad and drop down into the next valley where you can pick up a nice singletrack off to your right at CR-19. |
|
The trail pops out onto the paved road just before the water tower It is well worth it to hang the left and check out the views from around the tower. The hill to your east has a couple of trails on it with a nice trail in the valley between here and there. To the west you can still get some views of the Pacific on clear days. |
  From the water tower blaze down the pavement. Near the bottom of the pavement, the singletrack described earlier heads off to the right and back down into the valley where you came from earlier. Continue on the pavement just a little further and will you see a trail going off to your right near a gate that blocks the road from vehicle traffic (CR-44). Take this singletrack off to the right. Shortly after you get on this trail you will see a trail coming in from your right (CR-43). The official trail is the one on the right (That goes over to CR-42) but the trail to the left (That goes to CR-20) gets just as much traffic. Either one is good but in this direction the one to the left is quicker. Taking the left hand route you will come out to CR-20 where you will see a singletrack coming in from your left. Bear to your right and take the fireroad up to the junction with another fireroad at CR-21. |
  The hill in front of you to the north has three trail on it. All of which should be ridden. The trail between CR-19 and CR-20 that goes along the western side of this hill is the easiest single track of the trail to climb. It plenty fun to descend as well (Thanks SDMBA!) Here is the looping of these together I recommend. From CR-21, head down the fireroad to the Northeast (Purple on my map). Just as you are gather speed peel off to the right where you will start and easy climb. At CR-22 there will be a fork in the trail, bear to your left where you will skirt the peak by just a little to the west. At CR-23, stay to your right (there is cut over to the other trail you will ride later). You will now get to descend a little over a 1/4th of mile down to Valleyview Truck trail at CR-24. Hang a left and go a short distance (1/10th mi) to CR-19 where you will pick a singletrack on the left. |
 This trail is quite a nice well- built singletrack with lots of grade reversals and twists as it works it way back to CR-20 in 1/2 a mile. Once back at CR-21 take the fireroad again and peel off onto the singletrack off the left. This time when you get to the fork at CR-22 stay to the right. You will soon pass over the small summit and then you will start descending. There are lots twists as well as small trail features as you work your way down the hill to the northeast where you will pop out on Valleyview Truck Trail at CR-25. |

From CR-25 you can roll east down into the Crestridge Visitor Center area. The visitor center has some interesting architecture bits here and there. The trail(s) are marked in the immediate area of the visitor center so pickup the singletrack near the visitor center (CR-27). This single trail gradually works it way north east for 6/10ths of mile to the junction with another fireroad at CR-28. (Note prior to this there is a little connector trail that goes between CR-39 and CR-40). When you get to CR-28 you have options to the east but they require a commitment. This is about as far around on the "Basic Loop" as you should go if you are concerned about having enough juice in the tank to get back to the western end. I'm going to describe what I call the East Side Add-On before talking about the return route.. |
East-Side Add On |
  From the fireroad junction at CR-28 turn right and start gradually descending and follow it as it bends around from east to west. Half way through this turn (CP-29) is the junction of a short trail that goes right out to the Upper Rios Canyon Road trail head Continue on around the through the turn (still descending) as and you will soon see a fork in the road (CR-30) where you will bear to the right. The fire road starts a very gradual climb at his point. 2/10th of a mile after the last fork look for a singletrack going off the left and uphill (CR-31). Take this singletrack. This is the Flynn Springs Trail (It is unmarked). If the fireroad gets significantly steeper and then you come to a locked gate with a house off to your right you have gone too far. |
 |
  The Flynn Springs trail is about 1.75 miles long and goes through a nice bit of terrain. You will undulate but mostly climb through the first part of this area. There have been some reroutes as well as some spur trails that are in the process of be reclaimed. At about 3/10ths of mile onto the trail there is a significant spur that goes off to the left as the main trail bears off to the right. The spur off to the left goes out to an open area before dying out. Not much to see here so stay to the right. Just a little further down the trail is another spur go off to the left and slightly downhill through a small meadow (CR-33). This is an illegal trail that seems to be getting mostly equestrian use. It goes down to the bottom of the meadow where it pretty much dies out. Beyond this point the trail turns uphill much more sharply for a very short distance before it come up onto the western side of a small meadow (CR-34). There is a significant trail coming in from the right. This is section of trail that was rerouted that has not been reclaimed by nature yet. There are a lot of old moto tracks/trails in this meadow that the Earth Discovery Institute is trying let get reclaimed. While it is tempting to go check this out it would be best for continued public access through here if you just bear to your left and stay on the obvious main trail that goes northwest and uphill. |
   |
  At 9/10ths of mile since you got on the Flynn Springs trail you will come to the saddle (CR-35) of a sharp peak on your left. There is a spur trail at this saddle climbing off to your left on the east flank of the peak. That is is an unofficial trail that quickly dies out. The Flynn Springs trail beyond this point starts dropping elevation in a hurry losing over 600 feet in about 7/10ths of a mile. The trail is very rocky and technical in spots. The trail will come out onto a large firebreak (CR-36) where you will bear to your left and follow the break (and other tire tracks) to the west where it will soon turn north and downhill into Flynn Springs County Park. By now you should have figured out that trying to climb back up that trail would be a real Beeeautch so it is going to be avoided. Work your way out of the Park by following the road out. There is fence go-around east of the picnic area at CR-37 so you don't have to go all the way out to the main entrance. This will get out onto old Highway 80 (Two lane road here) where you will hang a left (downhill) and go about 9/10th of a mile where you will bear left onto Pecan Park Lane (CP-38) and soon there after make another left onto Rios Canyon Rd. |
 |
 Shortly after you get onto Rios Canyon Rd. the grade turns back uphill but it is very mile climb at his point. You will continue on this road just under a mile. Somewhere near the end of that mile the road switches from pavement to dirt. After the mile you will come to a closed vehicular gate (CR-38) and signage that you are entering the Crestridge Ecological Reserve. Continue onward and upward. |
  I have climbed much worse fire roads and this climb has some trees and turns to keep your eyes interested. It gains a little over 500 feed in just over a mile. It will bring you back up to the fireroad segment you were on earlier. While this is nice climb in the winter, it would no doubt be a fairly hot rough climb in the heat of the summer. At CR-39B the fireroad splits, stay to the right to get back on the Upper Rios Canyon fireroad at CR-30. Retrace our way back to CR-28. |
Return Route Options |
 |
So wither you have done the east-side add on or not it would be time to start heading back west now from Point CR-28. There is nothing wrong with just returning down the singletrack you came up to go back to the visitor center, but if you have not done it before turn westward from CR-28 and stay on the old fireroad. The trail starts of slightly downhill then flattens out. At around 2/10th of a mile you pass a little connector track back over to the singletrack you came up earlier. Continue straight where the trail will soon turn more downhill and into a fireroad that will become more maintained as it descends into the visitor center area (CR-41).Once back at the visitor you will need to decide which route you would like to take back to where you split off from the Valleyview Truck Trail earlier in the ride (CR-007). |
 EASIEST: The easiest route is to simply stay on the Valleyview Truck Trail. It is just a touch over 3 miles with the least about of climbing involved with around 500 feet or so with the worst grade being around 13% for a short distance. If you are already gassed when it is time to head back this is the route for you. It is also the least directional challenging route to follow. |
| HARDER: As you leave the visitor center area I recommend take the fireroad between CR-26 and CR-25 up to CR-21. Make a left and go CR-42 to CR43/44 towards the water tower. Taking the singletrack from CR-45 downhill and westward is an option but you will have a few bike swallowing ruts to contend with on your way to CR-12 and CR-11. Otherwise Climb up the pavement to the water tower and enjoy the singletrack from CR-46 to CR-47 back to the Valleyview Truck Trail at CR-16. Descend the road but be on the lookout for the trail going off to the left at CR-15. It is easy to miss going downhill. Take the trail to CR-14, CR-11 and CR-10 to get back up to the top (south) end of the valley. Hang a right to CR-05 and grunt up to CR-04 and peel off to the right for the sweet singletrack that will take you back to CR-03. Once you come out on the fireroad at CR-03 hang a right make your way down to CR-007 |
   |
  Whatever route you took to get to CR-007 from here you will want to take the singletrack that heads north from here. You are no longer on the Crestridge Ecological Reserve. You are going to drop a little over 500 feet in the next 1.1 miles. The trail starts out along a ridge line with a couple of undulations as it makes it way to large rock outcropping 4/10ths of mile down the trail. The rock has seen quite a bit of "artists" working on it. Your first time here it is well work a stop for a look see. One of the rocks looks like a howling wolf from the right angle. There is a fall line trail that heads off the north side of the rock outcropping (CR-238) that pretty much shoots straight down the hills. It is not a sustainable trail and quite frankly cashes out all the elevation to quickly without much of a fun pay off. Staying on the main trail is a much better deal for your well earned elevation points. From the rock out cropping the trail tightly twist back and forth down the hill. Near the bottom (CR-002) it will join the section of trail you were on much earlier in the right. Bear right at the switchback to return back down to the CR-001 and return to the Park and Ride lot. |
