Did this trail yesterday. Temperatures were comfortable in the low 80's. The hike down in the canyon was pretty well shaded most of the hike with the way back being perfect. Did this hike for the first time last August and it was beautiful and had so much water, so it was crazy to see how dry it was compared to last time. No evidence of any rain a couple days prior
Having a dog and a baby strapped to our chests, shade and water are necessary and this hike still provided though! All the springs along our route were going (some more so dripping or seeping) but did encounter some sizeable pools intermittently as well that Riley could jump in and cool off. Once we turned up the main Ash Creek Canyon it started to become more of a rocky section with some more water and nice pools and potential sweet waterfalls when running. Definitely worth a trip back.
(cairns seemed to stop when the trail enters the main ash creek canyon btw, but with all the cows down there its like a highway regardless)
On the way back decided to come back looping around in a side canyon and checking out Ash Spring. (which was dripping and had a small pool). There was also a pipe above the spring that looked like it was put there to direct run off water in the canyon above into the small pool? Anyway the canyon got a little choked up at times but nothing bad thanks to the cows! Returning this way we saw some beautiful oaks and a couple nice patches of pine forest.
All in all a great hike! Only complaint being all the cow crap. Definitely coming back when monsoon hits. On the drive out saw at least 10-15 deer, 5 turkeys, and 3 or 4 javelina!
