Waypoints (0)

Starting at Long Canyon Trailhead in the Trinity Alps Wilderness area. This tour of four stunning alpine lakes with a considerable amount of elevation gain in between. Passing through beautiful meadows surrounded by multi-colored granite peaks, this is a must-do hike if you’re in the area. Make sure to grab a wilderness permit before heading out to hike. Find more information at the park page by visiting https://www.fs.usda.gov/recarea/stnf/recarea/?recid=6521 The first couple miles are in the shaded pines but you’ll do a lot of climbing. There is a cold creek to get water at exactly 3 miles. The next few miles out of the pines are completely exposed until Bee Tree which is a great place to aim for a sit-down. From the Bee Tree, take the trail up and to the right at Deer Creek Pass. This is where you can decide if you want to head clockwise or counterclockwise on the loop. There are quite a few camping around summit lake but we were the only ones at Diamond. Users say to be sure to take the trail up to Siligo Peak before you hit summit lake- definitely worth it! The four lakes are a sight to behold and definitely a long full trip on well-maintained trails.

Started as the sun came up and made it to Diamond a little after 3. Not an easy hike and gets somewhat more difficult as you progress. Beautiful views and pretty secluded when we went. Had the lake all to ourselves first night and only one other person the second.

Absolutely fantastic 3D/2N lollipop loop up Long Canyon and around Siligo Peak via several spectacular alpine lakes.

Started at Long Canyon trailhead 9am Saturday morning and made it to Diamond lake at 3pm (7.1 miles) The first 3 1/2 miles are in the shaded pines but you’ll do a lot of climbing. There is a cold creek to get water at exactly 3 miles—may not really need to yet but I’d suggest filling up there because the next 2 miles out of the pines are completely exposed until Bee Tree which is a great place to aim for a sit down. From Bee tree take the trail up and to the right (we goofed and went left-down and it goes nowhere) at deer creek pass you gotta decide if you want to to head clockwise or counterclockwise. We pushed up towards summit and into Diamond lake and it was worth it, but if you have the steam and are only doing a short weekend, Ranger Jothom likes to get the hard part out of the way counterclockwise. There are quite a few camping around summit lake but we were the only ones at Diamond. 2nd day we did the loop clockwise from Diamond and you bet you’re buns we jumped into each lake! Luella is stunning and there were thousands of baby toads it was like a trippy flashback. You can climb the red rocks on the way out towards Deer for a stunning few and be sure to take the trail up to Siligo Peak before you hit summit lake (definitely worth it)

HikingGreat!

Incredible loop hike with amazing diversity in views. We did a 3D 2N trip and decided to stay at Deer lake both days. It was great to have the lake for ourselves before the weekend crowd set-in when we were leaving. Summit lake seemed to be the most popular to camp in. The hike in from Long Canyon is no joke, please be prepared for a consistent uphill slog (~6 miles) till Bee Tree Gap. Collected about a pound of trash from campsites and the trail while coming back. Please Leave No Trace folks and let's work together to protect our alpine heavens. Looking forward to coming back and exploring more of this amazing backcountry once the fire season is over.

Amazing 4 day trip last week! We camped at Summit for the duration and hiked the loop and Siligo Peak as day trips. The hike up is no joke - come prepared with as light a pack as possible. We went during the week after hearing weekends were crazy crowded, and still saw about a dozen people camping each night at Summit Lake. People were very respectful and quiet though, and almost everyone was wearing masks as we passed each other on the trail. Would definitely do this again.

My recording stopped on day one (operator error). On day 2, we continued up to Summit Lake. It was mid-week, but there were still four groups camping. On Day three, we hiked the loops to seek Diamond Lake, Lake Luella, and Deer Lake. Great hike with lots of ups and downs. My recording was on pause between Diamond Lake and Lake Luella (more operator error). We returned to Summit Lake for night three. On day four we hiked out. Easy going down hill. It was a Friday and I was amazing at the number of group hiking in. We passed at least 12 groups going in and only saw two heading out. Overall, the hike in on day one was extremely hard for our family of four (excluding my 16 year old who never gets tired). Days 2-4 were great. You should be in great shape if you want to do this loop in a day and I'd make sure to start early in the morning. Much easier to take a few days. Enjoy the mountains.

Day 1 of a four day hike. Days 2-4 on recorded and posted separately. We were a family of four. My wife wanted to do this hike to celebrate her 50th birthday (I married well). We got a late start around noon and it was warm. The hike in in very hard as others have posted. Essentially it is a straight climb. Most of it is in tree cover, but the last mile or so is exposed. I marked a good spot to grab water and take a break mid-hike. Our goal was Deer Lake, but we ended up camping short of Bee Tree Gap. Turned out to be a great decision. It is a really nice camp site with water and stunning views of Gibson Peak. I'd recommend this spot for those starting late or wanting to take it a bit easier on Day One. My recordings are posted separately for Days 2-4. Enjoy the Mountains.

Awesome trip! We left on Saturday afternoon and went for one night. You can get a free permit at the Weaverville Ranger Station on your way in. The trail up to the lakes is a tall climb. It seemed like a lot of people went up to deer lake and stopped there. This is a great area to stop if you want to do a day trip around the loop but I encourage anyone to backpack the loop! We passed deer lake at sunset and made our way to diamond lake. It was very busy everywhere on the weekend. Maybe 40 people at deer and summit lakes. We also had a gps tracker separate to alltrails that clocked the hike as a bit longer than stated. Maybe 20.5ish miles? Note: there is a side trail before you get to the junction that will take you down to a meadow in the valley behind the peak of summit lake. We ACCIDENTALLY took this and had a 2 mile addition to the trip. Watch yo’ map!

HikingGreat!

Did this hike over the weekend and it was spectacular! I had seen the photos but I didn't realize how breathtaking it would be. You start in the forest which is pretty nice but as you climb (and man, do you climb) the views open up and you learn how the Trinity Alps earned its name. Flowing streams, imposing granite peaks, incredible rockslides and overhead wildflowers had me singing "the hills are alive" for sure. We stayed one night at Summit Lake. With heavy packs, this hike was very hard. We started at about 1pm Saturday and finished at 4pm Sunday. It would be a challenge to do this in a single day, and it would be relaxing to stay two nights at one of the lakes and day-hike during the day. Summit Lake was crowded but there was enough space. Definitely a bummer to see a lot of TP and poorly buried waste. Might be more peaceful to camp at Deer Lake. We brought our dog (red heeler) and he did well, but it was pretty hot on Long Canyon. We saw another group with a larger, fluffier dog who was overheated. Be careful and know your dog's fitness and tolerance for heat. Getting stuck in the backcountry with a sick dog is bad news. Anyway, do this hike! Don't forget to get your free wilderness permit from the Weaverville Ranger Station.

This trail is no joke with all incline being at the first 8 miles...but it is SO worth it. Best trip I’ve done so far in my life. Each lake is beautiful and crystal clear and perfect to swim in, with a stunning view of striking mountains for each. There were a ton of people out this weekend, some said 40 at one lake one night for camping. One major bummer was that there was a ton of toilet paper out in the rocks of summit lake. Please pack everything out people, no one is going to come pick it up :(

Lots of wildflowers throughout the trail right now. Each lake is gorgeous and perfect for afternoon dips. Did this as a day hike and it was perfect—we had plenty of time for snacks and photos—though I was very sad to leave each lake. Please respect nature and others on the trail. No one comes all this way to run into your toilet paper and hear your shitty taste in music.

An exceptional trail. We approached via Long Canyon and spent 2 nights at Deer Creek Lake. The trail has a lot to offer- lots of wildflowers, marshy meadows, incredible views, and of course the gorgeous alpine lakes for swimming. Luella seems to be the best for a swim. Camping at the lakes can get crowded during the weekends; grab a spot early. But the trail itself wasn't crowded. Don't forget to hit the summit of Siligo peak, a worthwhile short detour.

Have been wanting to do this hike for years and finally got to it this past weekend! Wonderful weekend. We came in the Stony Ridge trail, which I'd highly recommend, lots of diverse terrain and beautiful scenery. We stayed at Summit Lake, which was really nice. We came in Friday afternoon and most of the lakeside spots were taken, but we walked a little back and took a spot on the ridge that made for a killer sunset. Seemed to thin out saturday and we then took a lakeside spot. Other reviews had me really worried about mosquitos, but didn't have any issues (and they normally attack me relentlessly). The loop itself was gorgeous, the lakes were so refreshing (you're damn right I swam in all four!). Back to camp for another gorgeous sunset. Highly recommend

did this as a 2d/1n with my 4.5 month old mini aussie on june 19/20. first day we hiked to summit lake - only a few areas we had to walk across a very small bit of snow. hike up was hard and steep. we started early so made it up before it was too hot. we camped at summit lake (7,400ft) - it got cold at night, upper 40s. second day we climbed siligo peak which is a must! diamond lake had a commanding view and i would definitely camp there next time. it did get really hot in the afternoon so make sure to start hiking early

Absolutely beautiful! This trail isn’t for beginners lol... it was intense! Bring lots of water and sunscreen! Some sections were a bit muddy and overgrown but nothing too bad! We did do this as a day hike which I would advise against it’s possible but we it’s so beautiful you will want to stay longer!
