Hiking/backpacking to Big Bear Lake and Little Bear Lake in the Trinity Alps is one of my favorite far northern California excursions. Trailhead access is easy, and I quickly get into beautiful sub-alpine granite wilderness. Note that the trail itself is relatively steep — you need to be in decent shape.

Granite-ringed Big Bear Lake makes an excellent day hike or overnight backpacking trip: A variety of plants line the trail on the way up, you’ll love the lake’s clear waters and steep glacial cirque, and it’s easily accessible from Highway 3. An added bonus: you can hike cross-country to stunning Little Bear Lake.
Trinity Alps Wilderness Permit and California Campfire Permit
If you are staying overnight, you’ll need a wilderness permit. Get one 24/7 at the Weaverville Ranger Station, Scott River Ranger Station, Big Bar Ranger Station, or the Coffee Creek Fire Station. If you plan to have a campfire, you’ll need a California Campfire Permit.
Trailhead Driving Directions
Take Bear Creek Road from CA Highway 3 on the west side, 18.6 miles north of Trinity Center, 10.5 miles north of Coffee Creek Road, 13.7 miles south of Callahan, and 6.8 miles south of Scott Mountain Summit. Go 1.6 miles to the small trailhead.
Hiking to Big Bear Lake
The trail begins beside the sign at the parking lot. Drop down 200 yards, approach the Trinity River, and then rock hop across Bear Creek. After the crossing, the trail begins the long westerly climb to Big Bear Lake in a forest of incense cedar, Douglas fir, and ponderosa pine and travels close to Bear Creek for the first mile. At 1.0 mile you’ll reach a footbridge and cross to the north side of the creek. The trail then switchbacks steeply up a ridge between Bear Creek and a smaller stream. Manzanita and huckleberry oak, two common chaparral shrubs, line and occasionally intrude onto the path, while numerous black oak and an occasional stand of knobcone pine provide some shade.
Approach the creek again at 2.1 miles and begin alternating between a mixed white fir and western white pine forest and lush open patches with numerous ferns. The first open views of the glacial granite cirques harboring Big Bear Lake, your destination, and cousins Little Bear Lake and Wee Bear Lake, appear at 3.1 miles.
From here, the occasionally steep route passes through numerous moist areas inhabited by mountain alder, fern, and some western azalea. At 4.6 miles the trail crosses granite outcrops, where rock ducks (cairns) guide you. Be sure to look back for an exquisite eastward view of Mount Shasta.
At 5 miles you finally reach Big Bear Lake, where steep granite walls tower over 1,000 feet on the south, west, and north sides. You’ll find good deep spots for swimming by walking to the steep granite on the east shore. Several adequate campsites, most shaded by mountain hemlock, western white pine, and Shasta red fir, sit above the lake near the outlet and near the east shore.
Cross-Country Hike to Little Bear Lake
If you have decent cross-country hiking and route-finding skills, you’ll want to make the trek to Little Bear Lake. Head a few hundred feet down the trail from Big Bear Lake to where Bear Creek tumbles down open granite and is easy to cross. Look southeast across the creek at the ridge just on the creek’s other side. Pick the easiest route to get on that ridge. From there, you need to angle east by southeast up about 400 vertical feet and over about .8 mile. Let your eyes and instinct help you find the way, and also look for a few rock ducks. Get the Trinity Alps Wilderness topographic map or the USGS Tangle Blue Lake topographic map to help guide you.
Little Bear Lake has good campsites on the east side, and you’ll love the granite glacial cirque and the easy access to the clear and deep waters. (Also see my Little Bear Lake video.) Small and shallow Wee Bear Lake is a couple hundred yards downstream via a faint path.
