Permits:  Permits are required year-round for overnight camping in Desolation Wilderness. During the summer (Friday before Memorial Day to Sept. 30), there is a permit quota for each different zone in the wilderness. Desolation Wilderness is split into 45 zones and the quota for each zone varies from 2 permits to 40 permits.  More info about the permits and zones can be found on the Forest Service website. Your permit only specifies your night of entry into the wilderness and the zone you will camp in on the first night. After your first night, you are allowed to hike and camp anywhere within Desolation Wilderness.

70% of the permit quota for each zone is available for advanced reservation on for a $10 reservation fee. The remaining 30% of permits are available on a first-come, first-serve basis on the day of entry. The day of permits are claimed and picked up at one of the nearby ranger stations.

Logistics: We planned this trip at the last minute. I was able to book a permit on Thursday night and then we drove to the Twin Lakes trailhead Friday afternoon after work. Since the hike from Twin Lakes trailhead to Island Lake was only 4 miles, we decided to go ahead and hike in on Friday evening rather than camping at the trailhead.

If you need to camp at the trailhead, there is Wright’s Lake Campground very close. This campground requires reservations in the summer though and can fill up quickly. Other options include many of the first-come, first-serve forest service campsites in El Dorado National Forest.

There is a parking lot near the Twin Lakes trailhead, where can leave your car during your hike. There is no fee for parking so long as you have an overnight camping permit and there is a restroom near the parking lot. For water, we did not see a tap at the parking lot, but there is a potable water tap at the nearby Wright’s Lake Campground.

Trail Conditions and Difficulty: This trail has several small creek and river crossings but it is unlikely that the water level would be too high to cross. We never had to take our shoes off and were able to rock hop across all crossings.

The biggest issue with this trail is that it is poorly marked in several areas. A mile or so into the trail, you are largely just walking on granite and there is no worn path to follow. There are strategically places rock cairns, which help with navigation, but it can be a bit tricky in places. Luckily the trail follows along creeks most of the time so you can be certain you are going the correct direction if you follow the creek. That said, you should have a map or have the route downloaded on your phone to help with navigation.

The trail is only ~3-4 miles long and thus is not very difficult. There is a bit of elevation gain, but overall this is a fairly easy trek. If you wish to hike up to the Crystal Range or Mount Price, you should be comfortable with scrambling and route finding. There is no maintained trail up the ridge and you must hike off-trail.

We wanted a relaxing and easy trip, so we completed our trek over 3 days. We camped at Island Lake two consecutive nights and just did a day hike on the 2nd day. The Twin Lakes area is a bit isolated by the Crystal Range Mountains, so there is not a super easy long loop from the Twin Lakes trailhead. We hiked to a small notch/pass just north of Mount Price. From this pass, it looked like it was possible to hike down to Lake Aloha (note that we did not actually hike down to Lake Aloha). If you are an experienced backpacker you could likely hike to Lake Aloha on day 2 and then head north and form a loop returning via the area by Rockbound Pass. Or, you could just do a short relaxing trip like that show below!



Supplies: There are black bears in the area, so you will want either a bear canister or a dry bag and rope for hanging your food. Doing so will also protect your food from the marmots and chipmunks that seem to search campsites for food.

You likely will want bug spray because the mosquitoes can be out in force in certain areas of the trek. I prefer a picaridin based spray because it does not damage plastics and synthetic fibers like high concentration DEET sprays do. I also like to pre-treat my clothes and tent with permethrin spray repellent. The permethrin treatment stays on your clothes for up to 7 washes, so it helps reduce the amount of spray you need to put on your skin.

The other essential item for this trek is an inflatable sleeping pad. Most of the campsites are on pretty hard granite or gravel surfaces, so a good mat makes all the difference. If you plan to hike up to the top of the Crystal Ridge behind Island Lake to get a view of Lake Aloha, you will want trekking poles and possibly microspikes/crampons. There were several sections on this ridge where we hiked across snow and the extra traction from crampons would have been nice. The trekking poles are helpful because you can use them for stability in place of an ice ax (unnecessary for this hike unless you are hiking down the backside of the ridge all the way down to Lake Aloha).

On the first day, we arrived at the Twin Lakes trailhead at 5:30pm. We began hiking at about 6:00pm and arrived at camp at ~7:45pm. We found a great secluded campsite (here), quickly set up camp, and then watched the sun set while cooking dinner. It can be a bit tricky to find campsites in the area. Most people seemed to look on the south side of the lake (opposite of where we went). It’s possible there were more sites on that side, but we really liked the site we found. Being on the north side of the lake lets you see the sunset over the lake and gives some fantastic views.

The Twin Lakes Trailhead is a short walk from the parking lot. To start the hike, head down the road and you eventually will find an information stand at the trailhead. There is not great signage at the beginning of the trail, but head towards Twin Lakes any time you see it on a sign.

Soon after hiking from the Trailhead at Wright’s Lake, the trail begins to meander through some trees. This area of the trail had some mosquitoes since there were meadows and streams nearby.  (pictured: Kelty women’s 50L backpack)
Shortly after the trailhead, you cross a bridge over the inlet to Wrights Lake.
The trail passes a small meadow and then goes through the forest.
Eventually you will reach a trail junction. Follow the sign towards Twin Lakes. At this point the trail transitions from a forest to granite. The trail is more difficult to follow on the granite, so keep your eyes out for rock cairns and other trail markings.

The trail then briefly passes back through the forest as it climbs.

Along the trail you pass several small waterfalls and pools of water.

When you approach Twin Lakes, there are several small lakes and pools of water formed by the stream at the outlet of the lakes.

This portion of the hike is really beautiful. Both Island Lakes and Twin Lakes would make nice campsites, but we figured there would be fewer people at Island Lake. (pictured: Carbon fiber trekking pole)

Day 2: 4.25 miles; +/- 1,700 feet; round trip Island Lake to Mount Price notch lookout

On our second day, we kept our camp at Island Lake and just set off on a day hike. The goal was to scramble up to the top of the Crystal Range mountain ridge near Mount Price. From the ridge we hoped to get a view of Lake Aloha. This part of the hike was all off-trail hiking, so I only recommend it if you are comfortable route finding and doing some basic scrambling.

We did not summit Mount Price, but instead went to a small notch/pass just north of the summit. From this notch, we found a great view of the Lake Aloha area. I would highly recommend this day hike as the views are great. Lake Aloha is beautiful and the views of Island and Twin Lakes are great as well. If you wanted to do a longer day hike, it appeared possible to hike down all the way to Lake Aloha. Again, this would be off-trail hiking so stay within your skill level. There was fair amount of snow on the north side of the pass (the side going down to Lake Aloha), so crampons and an ice ax would not be the worst idea.

There were lots of friendly marmots near our campsite.

There were a ton of small wildflowers on the ridge, which made the hike really beautiful.

We then hiked up a bit behind our campsite to get a nice view of Island Lake and the Crystal Range. From here we watched the sun set.
A great thing about this area is that the sunsets are amazing. First the lake gets shaded and the Crystal Range stays lit up by the sun.
Then everything gets shaded and shortly after the range begins to turn pink.
Shortly after, the Crystal Range lights up bright pink and the reflections on Island Lake are really beautiful. This process is awesome because it’s like you get two sunsets.

On the last day of our trip, we followed the Twin Lakes trail back to the trailhead. When we reached the trailhead, we rinsed off at Wright’s Lake and relaxed for a bit. When we were ready, we then headed back to our car and went home.

Even though the trail back is not as beautiful as the lakes, there are still some nice views.

    1. I can only speak about the situation in the Twin Lakes zone. There were definitely mosquitoes at the Twin Lakes Trailhead and during the first mile of the hike. They were not crazy bad, but they found you if you stopped hiking. Once we got out of the forest and onto the higher elevation areas, there was a breeze most of the time that kept the bugs away. At our camp on Island Lake, we didn’t even use repellent; the wind was enough to protect us. I’m not sure if it’s the same in other zones of the park though!


    1. All the maps are made at! The elevation data is from Strava data for those particular hikes. You can get elevation data from caltopo too though.


  1. GREAT WRTIE UP. Thank you. Heading up there 9/7-9 thanks for the detailed log. Doesn’t seem like there is a lot of trees (thinking for hammocking).


    1. Yes, there were not too many trees around the lakes. There were some trees near our campsite on Island Lake that seemed suitable for a hammock. Assuming you have a large group of people wanting to hang hammocks, you probably will need to look around for a while or decide to spread out a bit. There are not many areas with several large trees close together. You may be able to scope things out on Google Earth ahead of time and get an idea of what parts of the lake have the most trees though…


    1. We saw a lot of trout jumping at bugs in Twin Lakes as we hiked by. I do not recall seeing much fish action, if any, at Island Lake. I don’t remember much about Boomerang Lake either. If you plan to fish, I would target Twin Lakes first!


  2. Enjoyed this account of your trip! Especially the great photos! fyi, Island Lake has been gill-netted to remove the fish, in the interest of the Sierra Nevada Yellow-Legged Frog….


  3. Do you know of any longer loop hikes leaving from the Twin Lakes TH? I’d like to hit up Twin Lakes as part of a longer trek in desolation.


    1. Hi Jim – there is not a great loop from this trail so you must do a little back tracking. One option would be to head out to Lake Schmidell using the trail that sits west of Rockbound Pass. Then you could return via the Rockbound Valley and Rockbound Pass.

      Another option would be to hike out to Gertrude Lake. From there, you can hike off trail to Tyler Lake and then over the saddle near Little Pyramid Peak and down to Island Lake and Twin Lakes. From there, you can hike back to the trail head. I haven’t hiked this off trail section myself, but there are some reports online saying it is very doable.

      It is also possible you could combine the two itineraries above to make a bigger loop: Trailhead -> Lake Scmhmidell -> Gertrude Lake -> Island Lake -> trailhead.


    1. Hi Brett – The hike over the Crystal Range between Island Lake and Lake Aloha would be a challenge for most backpackers. There is no trail and you would likely be on snow for a significant portion of the hike. We hiked from Island Lake up to a small pass or notch near the Mount Price Summit. From there, it seemed possible to navigate down to Lake Aloha, but we did not do so ourselves.

      The best I can say is that the hike is likely possible, but you would want to bring crampons and an ice ax. You also likely want to have experience with off-trail hiking, especially on snow in steep sections.

      If you are able to get from Island Lake to Lake Aloha, there is potential to make a fun loop that incorporates those lakes, Clyde Lake, Lake Doris, Rockbound Pass, and Maud Lake!


  4. I am consider to go to the same area in early July. Would like to see wildflowers and avoid camping on snow(passing is fine), what time of the year did you go?


  5. Hi there! I am planning an overnight to Island Lake and want to summit Mt. Price (or at least the overlook that you made it to).

    Is there a way to send me the trail details or map of the path you made to the top?
