This is a nice loop that starts easy on an old, no longer in use dirt road leading into a canyon.
Eventually leave the nice trail and head down into the canyon. The canyon over time (after a fire) is filling up with (no problem) Ambrosia salsola salsola | Cheesebush and (problem) Senegalia greggii | Catclaw acacia.
Expect a couple of short stretches with small boulders and rocks.
Willow Springs, still holds a willow but no detectable water.
Warning: The route is to the best of our knowledge all in the Anza-Borrego Desert State Park, except maybe the actual Willow Spring.
Warning: As of 2025, there are "Keep Out" signs on the road. This may be legal or just put up by someone who wants to get rid of the weekend cars.
How to get here:
Take the Old Wilson Road (dirt), this is a reasonably maintained road and follow the main (widest) road.
