Cascade Lake Trailhead - Yellowstone National Park
The parking lot has 22 slots and a lane for 2 RV’s or trailers. This 2.2-mile (4.4-mile round trip) trail leads you through open meadows, pockets of forest, over a small stream, and through a wet marshy area before opening to a beautiful pristine blue lake that is rich with native cutthroat and grayling. See Fly Fishing Cascade Lake in the intro section for details. There are a few backcountry campsites just northeast of the lake.
Observation Peak Trail: When the Cascade Lake Trail reaches the north end of Cascade Lake a marker identifies the start of the Observation Peak Trail which immediately begins to climb 1,400 feet over roughly 3 miles through whitebark pine forest. As you make your climb look back to see Cascade, Grebe, and Wolf Lakes to the south and southwest.
