Formed by the Tieton Dam, the lake stretches across an open landscape framed by forested foothills and rolling ridgelines. Anglers enjoy fishing for rainbow trout and kokanee, while boaters and paddlers appreciate the expansive waters and scenic surroundings. Campgrounds and day-use areas provide easy access for picnicking, relaxing, and enjoying panoramic views.

The lake’s high elevation creates cooler summer temperatures and a peaceful atmosphere that appeals to families, photographers, and nature lovers alike. Seasonal changes bring shifting colors and reflections across the water, making each visit unique. Rimrock Lake offers a balance of accessibility and natural beauty, serving as a refreshing stop or extended destination for travelers exploring the eastern end of the White Pass Scenic Byway.
