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.
