Recently moved from the PNW and was using this app as my primary resource. The information provided was sorely missing. The hike started up Grass Mountain which is very steep (no switch backs) and very little shade. The trail past Grass Mountain is overgrown with Manzanita. Legs and area got very scratched. Made it to base of Zaca Peak and excited to find the dirt road to follow (partner and I wee very tired of bush whacking at this point). We continued on looking for the loop. Eventually encountered another very overgrown, dangerously hidden trail. Eventually we turned back and retraced our descent over Grass Mountain. Back through the Manzanita. The way down Grass Mountain is worse than going up. Loose dirt/gravel. I would never recommend this trail and was very disappointed with the trail description here. One star. Difficulty: Hard!

The trail is over grown with prickly weeds that will hurt you and stick to you. We hiked for about 10 mins and turned around because it was not enjoyable :(

Trail starts out fairly easy with lots of creek crossings. Once you start the climb it only continues to get steeper. Lots of sections with loose gravel so can be slippery at spots. Would recommend for only experienced hikers. Trekking poles would be helpful. Beautiful views and poppies starting to bloom 2/12/17

incredible views of canyons and valley on both sides of the ridge. The trail doesn't go to the top of zaca peak but instead traverses the ridge to above zaca lake and ends abruptly.
