Hours: 5 hours ( 9.2 miles out and back with 3100 feet elevation gain)
Difficulty: Medium-Difficult
Pet-Friendly: Dogs are allowed on leash. Will be difficult for your friend. There are many rocks and tiny stones on the trail. Some steep ascent.
Parking:Â Parking lot in Ice Hourse Canyon trail and street parking.
It start from the ice house canyon trailhead, and parking is pretty challenging if you come late. I was there about 7:00 am, the parking lot is already full and I park on the street. You need Adventure Pass to park in this area. The trail has many rock formation and stones are scattered every trail. It is not too steep, but there is gradual ascent and the last 1/4 mile was the steepest. I think this is similar the peak in the range, like Mt. Baldy. Continue to ice house canyon trail to Cucamonga Wilderness and ice house saddle. About 3 and half miles from the start, you will arrive the sign of Three Tee’s Trail. From there, you can reach three peaks in a row, Timber(8,303 ft.), Telegraph(8,985 ft.), and Thunder(8,587 ft.). 1/4 mile before the Timber peak, there is another sign that direct Timber peak. It gets steep here. The view from Timber Peak was great, and you will enjoy similar peak around you. The water following at the beginning was so much enjoyable and relaxed sound.
