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.
I try a lot of hiking boots and shoes, and there are some great options out there, but the La Sportiva Spire is the best combination of comfort, protection, low-weight, and durability. They are waterproof, and the high cuff keeps debris out without the need for a gaiter. Time tested over thousands of miles. Use them with a two-layer sock system to end blisters for good. Reviews & Lowest Prices: Women – Men
On a medium or longer hike I recommend a pack like the Osprey Talon 33 (men) or Osprey Sirrus 36 (women) which is a little bit larger. These packs are on the upper end of the (35L) daypack range, but they only weigh a small fraction more than a pack with less capacity. Having the extra space gives you more flexibility and means you don’t have to jam things in there. I use the space for things like extra layers in the winter, extra water on desert hikes, and even a tent & sleeping bag on overnights.
If you’re not familiar with the Garmin InReach technology, it allows you to send and receive text messages where you don’t have cell phone signals. You can also get weather reports and trigger an SOS to emergency responders. Even if you don’t have an emergency, sending a quick message telling a loved one that you’re okay or are running late is well worth the cost. The Mini fits in your palm and weighs next to nothing.

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.
I’m a big fan of GPS watches to follow my GPX track (which I also use as a sleep, wellness, and fitness tracker) and my current watch is the Fenix 6 Pro Solar (full review here). I load my GPX tracks onto the watch to make sure I’m in the right place, and if not, the onboard topo maps allow me to navigate on the fly. It’s pricey but it has a great battery, accurate GPS, and tons of functionality. If you want something similar without the maps and big price tag, check out the Garmin Instinct which is a great buy and does a lot of the same things.
