Hiked this trail July 2-4, 2020. Started at Swift Creek Trailhead, did counter-clockwise loop through Bear Basin, around Seven Up peak, and back via Granite Lake. One night spent near Seven Up peak. Trailhead: Swift Creek. Pretty easy to get to and can be done in a regular sedan. Slowly..but you’ll get there, only a few miles of dirt / gravel road. Trail conditions: Open highway, easy to follow. Some slightly overgrown spots coming back from Granite lake, but nothing major. Water: Always bring plenty of water! Creeks were flowing plentiful the whole way, except when you get near Seven Up turnaround theres not much water up there. Bug Factor: 1 out of 10. It was very pleasant, saw maybe 2 mosquitos the whole time. Dog Friendly: Yes. Crowds: Hiking back from Seven Up peak, passing Granite Lake we saw lots of campers and day hikers. The other side however (Bear Basin), there were very few people. Difficulty & Recommendation. Moderate difficulty - due to going counter clockwise though. Highly recommend counter clockwise. This was an amazing hike! Trinity Alps has so much to offer and this loop did not dissapoint. Views, meadows, mountains, waterfalls, wilderness and more.

Hi All - I just hiked the Granite Lake loop and want to give a quick update on trail and snow conditions. Weather was amazing! I couldn't have asked for better temperatures. Because of this, there were a lot of people on the trail. We hiked up to Granite Lake from the Swift Creek Trailhead. By ~1pm, most of the popular tent spots were full. We ended up sharing a site with another couple, which worked out perfectly since there were two fire pits in the area. Nights were cold but not unbearable if you have proper gear/clothing. 2nd day we hiked up to the saddle just below Seven Up peak. There was snow starting around ~6600ft with more snow in the Bear Creek Basin but not too much that you can't hike through.

Went over Memorial Day weekend and did the loop clockwise, which I'm glad we did (despite the crowds at Granite Lake). There was a large snow field coming down from Seven Up peak and into Bear Basin. Definitely got soaked sliding down, but the weather was warm and we dried pretty quickly. There is also a lot of water in the Bear Basin valley, and a few places where the trail is a bit washed out and finding it can be a little tricky the farther up the basin you go. Would recommend doing the full loop clockwise until there is more snow melt, and some gps and maps will help.

Highly recommend as a 2-3 day backpacking trip. We did it counter clock-wise, like the other reviewers, and really enjoyed this route.

Great route, plenty of wildlife including bears, be sure to follow sound practices when preparing and storing food at campsites. Did the route counter-clockwise and the climb out of Bear Basin was stunning with nice views of Mount Shasta a welcome bonus. Could easily be done as a two-day trip but three days allows plenty of time for taking in views. Granite Lake is also stunning but can be a little crowded.

Stellar loop. Hiked clockwise and enjoyed hiking past Granite Lake up to the apex of the hike. In early November, the winds were super strong once we rounded the ridge above the lake and started heading down. Moderately strenuous but a manageable day hike. On the top of the ridge, there are a few different trail options and none are very well marked. Took us a moment to find the more horizontal trail that loops back toward Swift Creek. Our loop measured about 15-16 miles.

There are some great sites along granite lake! Went in September though and the lake was very cold for swimming. We also left our stuff at our camp at granite lake and hiked the four lakes loop, which even as just a day hike with a lighter pack was pretty exhausting, but well worth it. You’ve gotta hike up the bowl of granite lake too, there’s some killer views up there and it doesn’t take long at all. We also saw very few other people along the route. Literally no one the first day. Definitely seems like a good way to go if you’re looking for less crowds as opposed to some of the other trails in the alps.

Follow a bumpy gravel road 6 miles to the trail head but totally approachable in a car. Did it on 5/27 which would be just barley outside the recommended season after a snowy season. We made it about 9 or 10 miles in going counter clockwise close to the north side of seven up peak with mountains surrounding giant meadows. This early we encountered several (4-5) river /creek crossings ranging from a 1.5 to 3 feet. after 6 miles, snow drifts covered more and more of the landscape interrupted by big lush green meadows, making the trail difficult to impossible to trace but we followed the Bear creek occasionally finding stone made pathways and lightly visible trails. We are for sure going to try this again when more snow has melted. It is totally worth it even early in the season if you like an adventure but would totally recommend past June depending on the season.

We have done this loop counterclockwise, and didn't regret it one bit as it has allowed us to completely avoid the crowds even though it was a long weekend. A word of caution: even though this trail description says the loop is 14.2 miles, in reality it's closer to 17-18. On the first day we walked 7.5 miles to Bear Basin and camped on an established camping site. The closest human soul was an entire 1 mile away, and we got an amazing experience of being alone in the wilderness. On the second day it took us another 5 miles to reach the Seven Up Pass. The Seven Up Pass was the most beautiful part of the hike. Wherever you are hiking from, make sure you traverse it! We were originally thinking to connect to the Four Lakes Loop from there, however, that trail involved going down into the Black Deer Valley and coming up on the other side just as much as we have just done out of the Bear Valley, and we didn't feel up to it. So we had an amazing lunch in an incredible tucked in spot at Seven up Pass and headed down to the Granite Lake. Granite Lake was a zoo - we counted 10 tents visible just from the trail! It really felt like there needed to be an established bathroom there at this point, it was so overcrowded. So we headed down to the car. The second day for us was 11 miles, which is a bit of a stretch with backpacks.

First to Review

Moderate hike to the lake, 5 miles in & passing some cool waterfalls along the way & good views of what's ahead when you emerge out of the forest & into a meadow. Then it gets steep to the gap, where you can see down into the Deer Creek basin, Round Lake, & across to Siligo Peak; & Luella Lake, tucked into a shelf. If you have time, you can just traverse the trail over to Bear Basin & go out that way, re-connecting with the Swift Creek Trail, for a total of 17 or 18 miles.
