    Tips

    June 21, 2026

    This beautiful lake sits at the foot of Mount Alderson’s dramatic cliffs, with noticeably turquoise water and surrounded by subalpine forest and rugged peaks. There is a backcountry campground and a pit toilet, and the lake feels genuinely remote, even though it sits along one of the park’s classic hiking corridors. It’s a natural place to rest during or after a long day of hiking, and is peaceful, open, and well worth the climb. You can also refill your water bottle here, just make sure to treat it before drinking.
