You can climb all the way up to the palms if you're the rock climber/mountaineer type. I'm not.
If you came just to see the palms, you might fail to notice what a nice place the canyon is at about 10:30 on a November morning. Quite. Startling fresh air. Interesting light on the canyon walls. There's a chance of seeing desert big horn sheep and other critters (it's a wildlife refuge, after all), though I saw none. I didn't care. I was happy.
The Rolling Steel Tent is parked somewhere down there
It's not the easiest trail, but an old fart like me made it up and back without incident
Sheesh, some people
