With so many famous hikes and excellent places to visit in California, the Trinity Alps is often overlooked. While the Yosemite and Mammoth Lake area hikes are top-notch, these trails have the potential to get crowded during the summer. Trinity Alps, a five-hour drive north of San Francisco, brings solitude, beautiful alpine lakes, and some of the toughest hiking and scrambling in California.
How to Get There
From Weaverville, California head up to Coffee Creek on Rt 3. Turn left on Coffee Creek Road. This road is OK for the first 5 miles. The next 13 miles is a poor conditioned dirt road. Big Flat Campground will be on your right hand side 18 miles in. The trailhead for the Old and New Caribou Trails begin here.
You can get a free backcountry permit from the Weaverville Ranger Station.
Day 1: 7.9 Miles, 2,526 feet gain, 4 hours 10 minutes
Day 2: 7.1 Miles, 2,536 feet gain, 3 hours 48 minutes
Difficulty: Very difficult
Old Caribou Trail – This is shorter than the New Caribou Trail, yet it is a very steep ascent directly over the mountain.
New Caribou Trail – The new trail goes around instead of over the mountain. A great option is take the new trail to the lakes, and take the old trail back to the trailhead/parking.
Caribou Scramble – Once you are in the Caribou Basin, the famous Caribou Scramble is an option for a side trip. This scramble up the Sawtooth ridge is extremely difficult and should only be attempted by advanced hikers.
Old Caribou Trail to Caribou Lakes
From the trailhead, it is best to start on the Old Caribou Trail. After a few miles these trails meet again. From this intersection, the Old Caribou will head directly up Caribou Mountain. Take the New Caribou trail from this point on. This trail will lead you to the Caribou Basin, with views of Sapphire Lake and Emerald Lake.
Where to Camp
Emerald Lake has great campsite spots, along the wooded side of the lake. We found a great spot with a fire pit and space for several tents. We set up closer to the trail, just on the bluff overlooking Emerald Lake.
The Caribou Scramble is a day hike from Emerald Lake. You can hike to the summit of the Sawtooth Ridge, which crosses the famous Caribou Scramble.
Return via Old Caribou Trail
After several switchbacks up from Emerald Lake, there is a 180 degree turn on the Old Caribou Trail and not going back around New Caribou Trail. Take this trail which ascends up to the summit of Caribou Mountains. Some of the best views are from this trail. From the summit, this is the most direct way back to the trailhead. The descent is very steep until you reach the juncture with the New Caribou Trail.
