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
Before venturing out to this location I read all the reviews. What hit me the most was the complaints about trash. So I grabbed some gloves and a couple 13 gallon bags and our hiking and fishing gear and we drove the hour. It is a beautiful location. Yes, there was A LOT of trash. We filled those 13 gallon bags with cans, broken glass, bottles (plastic and glass), shoes, shirts, shorts, swim trunks, fishing line. We filled both bags within the first 15 minutes. Mind you this is a river, the river gets high and this trash washes up higher toward the trail. It is a huge disappointment that humans can be this disrespectful, but this was a huge learning experience for my son. He is 14, he was sad at the trash and the graffiti. We decided instead of "never going back there" we will go back again and again and do the best we can to restore the habitat for all the wildlife we were blessed to see. We were able to see about 7 wild horses, quite a few ducks and to our surprise 2 bald eagles. It was great. There are a few trail markers, but not like you would see on some trails. We still enjoyed it very much. By the way this would be a can collectors paradise. Lots of money in aluminum along that riverbed!
Please don't turn away from this location because of the "trash" comments, it does not detract from the beauty of the surrounding red mountains, the river, the wildlife, the greenery. It really is a raw and natural place.
