I've hiked this trail and gone for a trail run out there. It's beautiful! You can access the canyon/trail from inside the Red Rock National Conservation Area or from Hwy 159 (if you don't want to pay to get into Red Rock, or the line at the entrance is too long).
As is pretty common for a trail in the desert mountains, there isn't much shade. If you go out here in the summer, you'll definitely want to be sure to apply sunscreen. The trail is pretty rocky, so be sure to watch your step - especially if you're not a super confident trail runner/hiker.
After a couple miles, you're treated to some gorgeous views, and if you go deep enough, you might be treated to some tiny waterfalls and pools.
