I suppose this trail is better suited for those with local knowledge. We attempted it, but couldn't discern the proper trail. Signs all over the place said "Park Boundary, no trespassing." We bailed out after :45 of trying to find the route!
After a boring start (from where you park, behind RM Elementary) to right after passing the wide basin, the canyon is spectacular. Right at the watering hole that's been built for the wild sheep, there is one climb after another but all easily doable if you bring the right shoes and free hands to grab onto the rocks. There are many palm groves all along and in the summer, during an early morning hike, there is plenty of shade, thanks to how deep the canyon runs in many parts. A few signs posted warn hikers to keep out... but people hike undisturbed all the same. Definitely worth trying!
Hiked this trail back in Sep 7, 2013, It’s one of the trail you’ll find inside the book 140 Great Hikes in and near Palm Springs by Philip Ferranti and Hank Koenig. It’s an easy trail along the canal; it’s when you pass the retention basin where the trail becomes interesting. The map in the book is not the greatest; you’ll need to double check in Google Earth. This is a trail that requires climbing up dry waterfalls and the first one is okay, it’s the second one that will end the adventure because it requires rope or a tall ladder. Since this trail is near a retention basin, be very cautious and prepared for mosquitoes. It’s the most dangerous and deadliest predator on the planet.
