"I bypassed Waterman Mountain while beginning the hike across from the Buckhorn entrance. The trail picks up Twin Peaks Trail eventually and continues to Twin Peaks. I ascended Twin Peak East first, then mostly followed a use trail to Twin Peaks West. After visiting the peaks, I always find the climb back out to be the toughest climb of the day." — MikeTeeples • Sep 17, 2022

"Started at Buckhorn Day Use Area and hiked up to Twin Peaks saddle, then a steep climb to the East Peak during which the cairns were helpful. Had the peak to ourselves as expected, enjoyed our lunch up there. Went back down then up again to Waterman summit, found a benchmark on top of a large boulder. Continued on the loop through Waterman ski area and back down to the trailhead. Really nice, love hiking around the PCT areas." — jodola • Jul 17, 2022

"Peak 2 of 3 on a warm August day. The first was Waterman Mountain (8,038'), and the third was Twin Peaks West (7,596'). I returned to the Mt. Waterman Trail Junction after summiting Waterman, and took the trail down the switchbacks to Twin Peaks Saddle (6,550'), and then a combination of use trail and cross-country (the trail seemed to disappear at times, so I followed climbers' cairns) up the very steep slope to the summit. I rested a bit, and as I started to descend, I saw how close Twin Peaks West was, so I hiked mostly cross country to it (there is some very faint trail here and there) and rested a small bit before the steep descent to the saddle and long trudge back up to the junction by Waterman. It is a very tough hike that took me all day, but I felt an awesome sense of accomplishment having done it. Elevation gain with all 3 is about 3,800'-3,900', with just Waterman and Twin East is about 3,600'. I was blessed to see several deer and a small group of Bighorn Sheep! The pictures came out rough, however!" — brianpowell • Aug 22, 2017

"I truly believe there are no bad days in the mountains but this may have been one of my worst. Tagged Twin en route to a Triplet Rocks summit attempt, the hardest summit in the San Gabriels by far (17 miles rt, 7500 elevation gain, 6 miles of it class 2-3 and bushwack only a few dozen have ever succeeded). Topped out on Twin in less then 2 hours from Buckhorn and excellent time and started descending toward Triplet. Found some bighorn trails that kept me off the ridge. Thought if I stayed low I could avoid the bushwack and tiring scramble. Hit a sharp rib running NE shown cutting through 5800' on the topo that I could get on top of but was cliffed out to get past. I foolish kept descending trying to get around it when I should have just climbed back up to the ridge. I dropped over 1000' before realizing the futility and climbing back up the loose chute, wasting an hour and a ton of water. It was still early so I pushed on, made it through the class 3 downclimb crux and up and over 6834'. At this point I realized I only had 1.5 liters of water left after using up too much during the unnecessary downclimb. I went a bit further to 6300+' when I decided I just wouldn't have enough wate..." — Christopher • May 30, 2013

"The saddle between Twin Peaks and Waterman was burned pretty bad. The way up is one of the steepest class 1 trails I've ever been on. Spotted a herd of ~30 big horn sheep dropping off the saddle into the San Gabriel River Basin, which made a good hike a great one." — Christopher • Oct 21, 2011
