Yeeehahhh! There is a mighty fine chance that you will not be able to resist the urge to scream that at some point during this 12 mile or so ride in the red rock hills west of Las Vegas. Wither it is the wide vista of the Las Vegas strip far below you from the top of Blue Diamond hill or the rocky technical goodness you will find on the "Bone Smasher" trail, you are going to find something to get you going here.
Directions:
From San Diego, drive a crap load of miles north on Interstate 15. After a
couple of tanks of gas or so you should be on the outskirts of Las Vegas, Nevada.
Look for the Blue Diamond/HWY 160 exit. Take that exit and turn west.
After about 12 miles turn right on highway 159. You will take
highway 159 maybe 10 miles or so. After passing by Bonnie Springs you
should see signs for the Red Rock Canyon National
Conservation Area Visitor Center. Take note of your odometer when you pass
these signs because the trailhead is 1 mile before the Visitor Center on your
right. There is a large Wooden sign in the parking area that says
"Horseback Rides". Park and ride.
Ride
Notes: This was my first (but not last) time out here and I must
say it was a heck of a
lot
of fun. I went with someone who already knew the trails so I do not have
much in the turn-by-turn directions department to give out. What will
generally work well is to turn right immediately after going through the gate and
start climbing along the singletrack. It is a little horse beaten at this
point, but quickly gives way to some nice rocky singletrack. If you turn
right at every opportunity you will get the most mileage in.

There
is one loop that can be easily missed, and is well worth being looked for.
As you are doing your climbing and taking a right at any splits, you will go
across a mine tailings pile. If I had to guess on your mileage from the
trailhead at this point I would say it was around two miles. The tailings
pile is fairly obvious as the rocks and
soil are quite out of place from the normal terrain. You will soon climb off the tailings
pile as the trail continues climbing while making a sweeping left followed by an
right hand bend. Just after the bend the predominant trail makes a 90
degree turn to the left and there is another (and much less used) trail off to
the right. Take this trail and you will be treated to some fantastic trail features that
includes some nice rock ledge moves on both the climbs and descents.
This trail will eventually take you back out near the tailings pile and the
trail you have already climbed once before. Retrace your route back to the
90 degree turn again and this time take the left and continue on the main trail.

Looking eastward from Blue Diamond Hill

After
you have had your fill of the view from the top, there is really only one way to go
as the trail turns downhill. There are drops here and there to keep you
honest so be on the lookout. Less than half a mile from the top there is a split in the trail.
The trail to the right goes downhill into a finger canyon and the trail to the left climbs up to a
ridge. To the right will take you down towards the trailhead, and
the left will keep up higher for a while longer. We went to the
left in order to get to the top of "Bone Shaker".

Bone
Shaker is an extremely rocky and often steep descent that has a bunch of two to
four foot drops that require you to be on your toes. There are also a
couple of five foot or so drops that go out of the roll category into the huck
zone. Additionally, the bottom gets extremely loose with some
tight switch backs that will test your bike handling skills. While you can
go really fast in some sections on this trail, it is the technical features and setups required for some to
the combination moves that make this a great trail in my book.

The
bottom of Bone Shaker dumps out into a small meadow. Also coming into
this meadow is the trail that I mentioned above that split off to the right near
the top of Blue Diamond Hill. We turned to the left and worked our way
gradually down the meadow until the trail came out on a dirt road. We
turned to the right and followed the dirt road back to the trailhead that was
not more than a half mile away. This was a great opener for my Nevada - Utah
2006 Road Trip.
