"Before reaching the vehicle gate on Mount Disappointment Road, a single track trail leads up a gully. The trail climbs for about 1,000 feet of gain while paralleling the road at points. I climbed San Gabriel Peak first, followed by Mount Disappointment, then Mount Deception. After the third peak, I took the road back to the parking area, creating a semi-loop hike." — MikeTeeples • Oct 8, 2023

" 12/24/22 We started this hike at 8 AM. The trailhead has a great view into the interior of Angeles National Forest. Then we started through the Mueller Tunnel and then ended up at Markham Saddle. Then we summited Mt Disappointment and saw our first snow. But we used a steep shortcut to the top. The summit of Disappointment has great views towards the city, but there is a great view of the foothills as well. But there is a disappointing view of the mountains. up the steep ere is a better views of the mountains from the road. Then we went to San Gabriel Peak. There was a huge snow patch along the trail. Then we summited San Gabriel Peak. It has enhanced views of the city and the mountains and had a benchmark. Then we continued back down to summit Mt Markham. So, we climbed through the shade on one side of Mt Markham and then summited Mt Markham using the use trail on the ridge. The views from Markham were great, but the hard work made the summit not as worth it as I'd expected. Then we continue down to Mt Lowe. The summit had great views of the city and San Gabriel Peak and had some pairs of binoculars and good info. Then after that returned to trailhead." — lc444 • Jan 1, 2023

"On a wonderful, spring-like day, the San Gabriel Mountains front range lured me to take a multi-peak hike. I started at the very busy (as usual) Eaton Saddle trailhead, went to the major trail junction shortly after the Mueller Tunnel. I took the right onto the San Gabriel Peak Trail and visited San Gabriel Peak first and enjoyed the lofty views. I then went to the San Gabriel-Mt. Disappointment Saddle and took the paved road to Mt. Disappointment. The equipment on the radio towers made a loud beep which was annoying, but being a summit lover, I did not let that detract from my enjoyment of Mt. Disappointment. I then returned to the major trail junction, and then I headed up the Mt. Lowe Trail to the saddle between Lowe and Markham, and scrambled up to Mt. Markham, returned to that saddle and visited Mt. Lowe. It was a wonderful outing with about 6.5 miles round-trip and about 1800' gain." — brianpowell • Mar 12, 2022

"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
