Thumb Geyser
Saves: 51
Check-ins: 11
The backdrop of the Yellowstone Lake makes this geyser a particularly unique anomaly. To get there find the trailhead on the west side of Yellowstone Lake near the Grant Village Visitor Center. The trail loop is about two-thirds of a mile and is pretty easy to walk. It is also wheelchair friendly. You might also spot some elk and bison. As always, stay far away from the bison for safety.
