The Three T’s Trail hike is one of the more peaceful hikes in the Mt Baldy area. This loop hike starts at Icehouse Canyon, climbs to Icehouse Saddle, then hits Timber Mountain (elevation 8,303ft), Telegraph Peak (elevation 8,985ft), and Thunder Mountain (elevation 8,587ft), and then descends down to Baldy Notch, Manker Flats, and back to Icehouse Canyon. It’s a long hike, but a favorite for those avoiding crowds.
This is a long, tough hike. Don’t attempt it if you haven’t done long mountain hikes and if you don’t have a good level of fitness. Start very early to avoid the heat in summer. Likewise, if there’s snow and ice on the route, don’t attempt it unless you have winter hiking and mountaineering experience.
You need a parking pass for the Icehouse Canyon Trailhead lot. I use the affordable National Parks Pass, which gets me in every park, monument, and national forest. You can also use a (Southern California only) Adventure Pass, or buy a $5 day permit from the visitor’s center.
Gear for the Three T’s Trail
This is a backcountry hike and you should prepare accordingly. It’s also a hike best left for times when there’s no snow or ice.
Telegraph Peak is a great place for a lunch or snack break. You can also eat at the restaurant at Baldy Notch on the way down.
No company pays me to promote or push a product, all the gear you see here is gear I use and recommend. If you click an REI link and buy gear, I get a small commission that helps offset website expenses. There is no cost to you.
Three T’s Trail Maps
These directions are for a loop hike. It’s designed to let you take in the beauty of the Three Tee’s Trail and then you have a nice long descent back to your car. The descent includes a road with cars for a bit. If you want to avoid the more developed portions of the hike, simply hike to Telegraph Peak and return the way you came.
This thing does everything: maps, GPX tracks, compass, barometer, altitude, heart rate, blood oxygen, fitness tracking, sleep tracking, and the list goes on. I keep a GPX route on the watch so I can quickly glance down and make sure I’m in the right place.
I load a few types of offline maps onto my smartphone when I need to interact with the map in detail. I also use it before my hikes as a planning tool for all kinds of things, including finding free government land to camp on. The benefits are many, I highly recommend it.
Don’t be caught out if your batteries die. Take a topo map with you on the trail and learn how to read it. Some people also print my guides out for use on the hike. I’m a map geek and I love to pour over maps and guide books when planning my next adventure.
If you want to avoid the more populated trails, you can simply turn around here and retrace your steps back to the Icehouse Canyon Trailhead. The rest of the hike directions here follow a loop route back to the hike start.

If you see trash on the trail, please pick it up and carry it out. Be a good egg and practice no trace principles.
