The place is beautiful. The trail itself did not have trash but down by the water there was a terrible amount of trash, old clothes, and lots of beer cans. Didn't get a chance to see the wild horses but the trail was a lot of fun, not too hard but not super easy, it was a good workout with beautiful scenery. You MUST get a recreational pass to park, we parked without one and didn't get a fine but it's best not to take chances.
RECREATION PASS REQUIRED ! You need a recreation pass to park near this trail which is not available anywhere at the location .. you need to drive back to the town to get one at a gas station. So if you are heading to this place, please make sure u buy the pass on your way to the trail. We were very lucky to find someone who had an extra pass that we could buy- Bless that soul. It's a beautiful trail , very green amidst the cactus and the weather was brilliant in February. We didn't see any trash so I'm guessing the good samaritans did an amazing job of cleaning up the place
