This place is amazing!
You are surrounded by peaks in every direction and can easily access multiple different points of interest depending on the adventure you want.
There are spread out campsites that you can pop your tent at and it was not crowded when I was there. Because you are at higher elevation it does get rather cold at night so keep that in mind and check the weather since it can change rather quickly.
Wonderful backcountry camping accessed by a mostly uphill 2 mile hike. You are surrounded by the peaks of South Sister and Broken Top and are welcomed each morning and night with the gorgeous sunsets and sunrises. These camping sites make for a perfect spot to catch some rest before making the hike up to the summit of South Sister. The lake sits below the Lewis glacier and, like many alpine lakes, the lake stays frozen for several months out of the year and the trail can be packed with snow as late as August.
Campsites are located above the lake on two sides and are under tree cover for those rainy nights. To reach the sites you will need to take a right at 1.5 miles in on the trail. There is no potable water nearby. Pack in and out all waste and everything you will need for the night. Make sure to bring bug spray as the mosquitoes love that chilly lake.
Hiked up on Friday night and got the last spot. No amenities, and a 2 mile straight uphill hike to get here. Theres a map of the campsites, but they are hard to find. None are near te lake so fill upwater in bulk! Stunning sunsets and sunrises. Made for a nice striking point to the summit. Gets busy. Have bug spray handy!
