Sprague Lake is a scenic lake in Rocky Mountain National Park (RMNP), located on the south side of Glacier Creek, about two miles south of the Hollowell turnoff. The .9 mile walk around the lake features boardwalks and bridges with views of Flattop Mountain and Hallet Peak. The area is named after Abner Sprague, who started a homestead there in 1874. The area became part of Rocky Mountain National Park in 1915.
