The Triple T or Three Tee's Trail is a lengthy scenic loop that covers Timber, Telegraph and Thunder mountain. You have an option to do this as a 13-mile loop or a 16-mile out-and-back. 

It starts at Icehouse Canyon Trailhead. Make sure you come early in the summer months because the parking lot can easily become full. The trail starts along the creek, which is the only water source on the trail. The first part of the trail is shaded, but it opens shortly. The trail can be a bit vague with surrounding boulders, but it becomes more visible as you continue. 

After 2 miles you will arrive at the saddle, which is a perfect place to take a break before continuing on. From here the trail splits into different directions. Make sure you take the sharp left and follow the sign toward Timber Mountain, which is only 0.9 miles from the saddle. To get to Timber Mountain, you take the short side trail. You can follow your path back and continue on to Telegraph Peak. From Timber to Telegraph, it's about 3 miles of rolling hills to the junction toward Telegraph Hill. Make sure you take the side trip to the peak as the view from the summit is astounding. 

From Telegraph Peak, you can see Thunder Mountain and Baldy Lodge. You will drop down then climb back up to Thunder Peak where the ski patrol hut and the top of the lift is. From here, decide whether to go back the way you came or continue down toward Baldy road toward the parking lot. If you do decide to go down Baldy Road from the lodge below, you can take any fire road. Once you reach the parking lot, you will have to walk on the road for 1.5 miles back to your car unless you can get a ride from another hiker who's heading down. 

This trip feels somewhat like a choose-your-own-adventure because there there isn't a set itinerary. You can go as far as you want, turn around, or continue on as a loop. Either way, it will make for a fun day of long adventures.
