Agua Caliente Canyon Trail: an alternate descent to the same finish as Milagrosa. Also known as "Gnat's A**" on Strava. The top is clearly marked with a cairn. Mostly fast tech without any huge features, but lots of rocks to spice up line choice. Lots of loose sections as well, but not enough to bog you down--just enough to test your skills to keep traction. While descending, there are basically no HABs, which is a relief if you just climbed Agua Caliente. Overall this trail is a bit easier than it's neighbors, but it is still not an easy trail. The trickiest part is at the bottom: there are several steep, tight, loose, rocky switchbacks. They are a fun challenge to end on.

Hikers use this trail too, but it's usually not very busy at all. Climbing this trail does involve some HAB, but a skilled, strong rider could probably ride about 75% of it. Climbing it is less difficult and shorter than climbing Agua Caliente.

      The trail is pretty overgrown, especially near the top, to the point where it's hard to even see the trail

      The bottom part after the gate is mostly unrideable...just to too short of switchbacks and very tight with lots of loose rocks. Climbing the lower part would be equally unlikely. The upper part is ok but I'd say this is too much a hiking trail and should not be on your trail ride list. Just no real payoff going downhill. Don't waste your time unless you just want to say been there done that.
