"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

"I took Mt. Disappointment Rd from just off Mt. Wilson Rd, near Red Boxed. I visited Mt. Deception first, and after climbing up and down the use trail for Deception I wanted to revisit Disappointment's summit for the second time. The first time I hiked Mt. Disappointment, I hiked up the Bill Reilly Trail and combined it with San Gabriel Peak, but this time, I took the scenic and often viewful paved road with groves of Coulter Pines, live oaks, and Bigcone Douglas-Firs. The road's incline is mostly mellow except the last stretch to the towers at the summit. Overall, a pretty easy hike with peaceful vibes! I truly enjoyed hiking with the pines here! Elevation gain is roughly 1,200ft. The views on the peak are sweet!" — brianpowell • Dec 23, 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

"First of two peak hike this day (second was neighboring San Gabriel Peak (6,161')). Moderate hike up Bill Reily Trail from Red Box Area. Lovely oak forest along way up Bill Reily Trail. I intersected Mt. Disappointment Road and headed to radio tower capped summit. Then, I headed to San Gabriel Peak Trail to the namesake summit. I returned from San Gabriel Peak to the saddle between both peaks, then down Mt. Disappointment Fire Rd. to Bill Reily Trail back down to the parking area at Red Box." — brianpowell • Mar 7, 2015

"I rode my bicycle up Chaney Trail, up Mount Lowe fire road, thru Mueller Tunnel, and up to the top of Mount Disappointment. Started below the clouds and finished above the clouds." — ken.chanaud • Jun 28, 2014

"Peak #2 of 5 on 11 mi RT. San Gabriel Peak trail to 2nd junction with Mt Disappointment Rd. Took Rd to the saddle between San Gabriel Peak and Mt Disappointment, then up to the ruins of the old Nike SAM installation and multiple antenna towers. Then back down to the saddle." — srphilip • Jan 8, 2012
