Nightmare Gulch is a very challenging yet highly scenic 4x4
trail in Red Rock State Park. This trail will offer jaw-dropping
beauty as well as jaw-clenching obstacles. For both reasons, we
highly recommend it!
Note! Nightmare Gulch is closed to vehicle
traffic during the first half of each month, but can be accessed on
foot or horseback. Vehicle travel is ONLY permitted during the
second half of each month. We suggest you verify opening dates with
the Red Rock State Park rangers. Also, note that the area is closed
seasonally (normally in February through June) for raptor
breeding/nesting. Do not even think of trying to enter Nightmare
Gulch during the closure periods!
Speaking of vehicle access, you are entering at your own risk.
You WILL need a 4WD vehicle; stock 4x4s--especially longer (F-350
types) and wider (Hummer, etc.) ones--are NOT recommended. I
imagine, say, a stock Jeep Rubicon could make the journey
unscathed, but be forewarned that there are boulders, narrow slots
and tight, off-camber turns with rock overhangs, and body damage is
a very real possibility. If you have running boards on your stock
vehicle, expect them to be smashed. That said, we ran three
vehicles--our Rubicon, a Cherokee, and a Grand Cherokee, all lifted
with at least 33" tires, and we had no new scratches save for some
fresh marks on our skid plates. As with any reasonably challenging
trail, I always recommend bringing more than one vehicle along.
Take your time and pick your lines carefully.
Normally, 4x4 groups run Nightmare Gulch west-to-east, starting
at Hwy. 14. Start at N 35° 22.630 W 117° 58.840 and follow the
trail to the east; at some point you will reach a signed junction;
follow the sign for "Scenic Canyon."
You're looking for a 50-caliber ammo can hidden amongst the
rocks on the south (right-hand, if approaching from Hwy. 14) side
of the trail. You'll need to do only a few feet of climbing to find
it.
Good luck, and happy caching!
