A dirt road leads to a ranger station, parking and horseback or hiking trails. The trail to Bluebird Lake and Ouzel Lake follows the North St. Vrain Creek (which is a tributary of the South Platte River) [1] passing Calypso Cascades and Ouzel Falls along the way, leading to Ouzel Lake and Bluebird Lake. Both Ouzel Falls and Ouzel Lake are named after a North American species of bird, Cinclus mexicanus , also known as a dipper. [2] Other trails lead to Thunder Lake, Finch Lake, and Pear Lake.
