West Thumb Overlook Trail — 1.9 miles, 291 ft gain, Yellowstone

West Thumb Overlook Trail in Yellowstone National Park overlooking a steaming blue thermal pool with Yellowstone Lake beyond.

West Thumb Overlook Trail is a 1.7–2 mile loop with about 200–400 ft of gain. This moderate climb demands a steady pace, but the payoff is an open overlook with West Thumb Lake framed by the Absaroka range.
