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.
(This post is based on chapter 56 of my book 100 Classic Hikes: Northern California, fourth edition.)

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.

Wish I’d known you when I lived in northern California… I think I’ll gift my daughter your book come Christmas.
Very nice, John! Looks like one I keep missing, but not for long!
Also try to get to Little Bear Lake Tom. I prefer it to Big Bear.
John,
Had to write and say our Boy Scout Troop just completed a 50 mile hike (54.2 exactly) through the Trinity Alps, specifically Deer Creek, Swift Creek and Union Creek drainages. Thanks to an article in Backpacker Magazine from May 1999 and your trip description to Emerald and Sapphire Lakes from 2010, we spent 7 nights and 8 days at Big Flat, Snowslide Lake, Caribou Lake, Emerald Lake, Deer Creek Camp, Mumford Meadows and Union Lake. Caribou Scramble (Suicide Ridge) was something else. Elevation gain/loss was also intense but we all had a great time deep in the mountains, swimming and fishing the lakes, implementing Leave No Trace and taking in all the grandeur. Truly a trip of a lifetime. We hope to get back up there next year sometime. Thanks for the inspiration. And on a final note, I picked up a copy of your book, “100 Classic Hikes of Nor Cal” and look forward to reading it….many of the hikes you list I have previously have completed.
Hi Matt,
Would please give me more details of your trip. I’m an ASM with Troop 259 and would like to take my scouts to Trinity.
Thanks!
I can provide as many details as you like. I can also scan and send some things. Just as my note to John states, we started at Big Flat, camped at Snowslide, Caribou and Emerald Lake (yes, up and over Caribou Scramble (aka suicide ridge) then headed east and looped back out of Union Lake.
Rather than me listed a bunch of items, let me know specifically what your questions are and I’ll answer them.
Matt
Matt, thanks for writing. I’m so glad that you and your scout troop had such a good time in the Trinity Alps. That’s a major excursion y’all completed!
John, thank you for sharing the post. I live in nor cal and am about 3-1/2 hours from trinity (chico/oroville). I have not had the chance to hike in that area yet as age (more being out of shape:) is getting the best of my lady and I but I have to say, after looking at those pictures I have to get up there. I always knew there was a reason I came to cali and that looks like it. Absolutely beautiful.
Hi John,
I live in Humboldt County and love to backpack in the Trinity Alps. I’m new to the game but everyone was new once. Just finished a three-day trip to Tangle Blue with a day trip up past the Marshy Lakes and up to the PCT. Crazy good time.
I am wondering if you have any information on how to get to Log lake north of Big Bear lake. I have looked all over and can’t seem to find any information. My girlfriend thinks I’m nuts for wanting to go there so badly but nuts or not, I do.
Any help would be great.

Thanks,
Kevin Johnson
I’ve read that people have done it by leaving the Big Bear Lake trail a half-mile or so below the lake and hiking to a saddle just above Log Lake. There’s a lot of brush on that slope. Good luck with it!
John,
I know that you are an avid backpacker so I hope that this question is not too far fetched. My wife and I do a lot of hiking, mostly day hikes, 8miles to 14 miles. Can you recommend a good spot to set up camp where one can access a number of good day hikes? I plan to purchase your book of hikes in the Mt. Shasta and Mt Lassen area. Have been to the top of both of those mountains. Are there good day hikes on, around Mt Shasta? I will appreciate your reply. Thanks
Richard
Richard, there are a dozen or more great day hikes in the Mount Shasta area. Most are on the mountain itself or in the Trinity Divide mountains to the immediate west, including Mount Eddy. Not in my book is the Lake Siskiyou Trail, which encircles the entire lake and can be accessed from many points.
John
Do you know of any great Trinity Alps lake hikes for an overnight trip that are a little closer to Arcata?
Yes the Canyon Creek Lakes. See this post:
https://northerncaliforniahikingtrails.com/blog/2014/06/26/canyon-creek-lakes-trinity-alps-boulder-creek/
Can you have a campfire at bear lake?
There is relatively little wood around the lake, so it is best that you don’t have a fire. It’s important for the ecosystem that whatever little wood remains is allowed to decompose naturally.
Hi John,
Can you recommend a 50 mile or so hike in Trinity?
Thanks!
Ike, it’s too difficult to recommend a 50 miler in the Trinity Alps. There’s no obvious one long trail. It’s possible to do, but I’d have to know a lot of info about you, your companions, your fitness level, your experience as hikers, how much time you have, how well you can find routes, etc.
Hi John,
I too am looking for a 50 miler (and will consider what the scouts did a few years ago. I am very fit, good at route finding and open to most any challenge that doesn’t involve ropes. I will be going solo, so nothing too risky. I regularly run ultras in the mountains (30+ miles in a day with 5K+ elevation). One thought is to go in, set up base camp and then do some long day runs from a camp or two so I can see more ground.
I plan to go end of July and thinking mosquitoes will not be an issue, but hate to get caught with out bug netting in shelter, but leaving that behind will save me 2 lbs. Thoughts?
Any advice is appreciated.
Cheers,
Chris
Chris, consider doing the Four Lakes Loop from the Stoney Ridge trail. Once there you’d have several options for day runs.
Thanks John 🙂
I did this hike last weekend for my backpacking trip John, absolutely beautiful!!!
I’m glad you liked it, Janette. Did you get to Little Bear?
Made it up to Big Bear this weekend. Temps were hot, bugs were plentiful, and surprisingly not too many people. Lot’s of great birds out, and made a trip over to Wee and Little Bear Lakes as well.
Good for you, Jason! Any ice on Little Bear? Someone else told me it still had some ice as of a week ago or so.
I plan to get to Big Bear later this summer.
Hiked to Big Bear Lake yesterday with 3 girlfriends. We’re in our 50s-60s, In good hiking shape. Suggest bringing water shoes for creek crossings and plenty of water or a filtration kit, it’s getting pretty warm up there. Gorgeous views abound. Watched an eagle having her/his lunch from our lunch spot.
Sounds like you had a great time. Big Bear Lake is one of my favorite hikes in the Trinity Alps.
And you’re definitely right about water: bring plenty or bring a filter.
