"Troop 128 climbed 4 San Gabriel peaks for a Philmont training hike. We started with San Gabriel Peak, hiked over to Mount Disappointment, on to Mount Lowe and finished with a scramble to the top of Mount Markham. Very difficult hiking especially with backpacks." — mattjohnson • Jun 13, 2021

"Walking through the Mueller Tunnel was pretty cool. Checked out the old Nike Site first and went up to Mt Disappointment. Then back down to the saddle and up to San Gabriel Peak. I'm sure the views would have been great on a clear day, but was fun hiking through the chilly clouds." — jodola • Mar 8, 2021

"This was peak 3/5 on the Sierra Club WTC Trip. Others had done some trail work on the San Gabriel Peak trail, so the hike up to the summit block is less sketchy now. The way down was a bit steep, though." — ctrain2018 • Dec 9, 2018

"This was a great hike to 4 different peaks. Each trail to the peaks were different as well. Gabriel peak was a nice single track with amazing views. Mt. Disappointment was a paved maintenance road with nice views as well. Walk back down to the main trail and take the Mt. Lowe trail (not the fire road) up to the Lowe summit. It’s very special with amazing views. The trail is pretty easy as it’s a wide trail and plenty of shade. Go back down the same way to reach the trail to Mt. Markham. This trail is technical and fun. Wear pants for this one because of the Spanish daggers and other sticker bushes. There is some scrambling in certain spots but the summit has completely different amazing views than the other peaks. It’s worth the effort. Just follow the path, take your time, and watch your footing. It’s doable! I took leisure time throughout this hike and enjoyed the views and scenery. It’s fun and very worth doing all the peaks in one hike." — rickb • Jan 5, 2018

"Night climb to see the sunset/supermoon lunar eclipse. The climb up was pretty routine, but the climb down at night can get dicey because the San Gabriel Peak Trail is somewhat exposed close to the peak." — ctrain2018 • Sep 27, 2015

"Second peak of two summited that day. First was Mt. Disappointment. Moderate Hike up Bill Reily Trail accessed from Mt. Wilson Road near Red Box Picnic Area. Bill Reily Trail intersects Mt. Disappointment Fire Rd, and then heads towards Mt. Disappointment Saddle at roughly 5,700'. It then ascends towards tower-capped Mt. Disappointment (5,963'). I headed back down to the saddle, and then took the San Gabriel Peak trail to 6,161' summit. Lovely Canyon Live Oak/Interior Live Oak forest along Bill Reily Trail, and nice views from both summits." — brianpowell • Mar 7, 2015

"After Markham and disappointment we climbed San Gabriel Peak. I have been wanting to bag this one for so long and now I finally got it. Pretty amazing up here too. This finished up our 3 peak day and was peak #57 of my 100 in 2014 goal." — 1-with-Nature • Aug 10, 2014

"This was the third summit of a 3-peak day with the HPS group: Lowe, Markham and San Gabriel. Spectacular views today! Even though there were a few clouds in the sky, we could see Baldy, San Gorgonio and San Jacinto to the east, cargo ships in the water off Long Beach to the south, the ocean to the west and downtown L.A. seemingly at our fingertips." — HikerMark • Mar 9, 2014
