Diamond Lake
A high mountain lake just outside the park's north entrance, mirroring the sharp peak of Mount Thielsen, with a resort, lakeside trails and water activities.
Diamond Lake lies within Umpqua National Forest, about 10 km north of the park's north entrance. The lake covers around 12 square km, and from its east shore you can see the sharp summit of Mount Thielsen, nicknamed “the Lightning Rod of the Cascades.” Around the lake are a resort, campgrounds and an 18 km bike path circling the shore. In summer you can rent boats and kayaks or fish for rainbow trout, and in winter it becomes a base for snowmobiling and cross-country skiing. Many people use it as an overnight base when entering Crater Lake from the north. Blue-green algae advisories are sometimes posted in summer, so check the notices before swimming.
