Lone Star Geyser

Lone Star Geyser, Yellowstone National Park, WY

Here’s a little-known fact about Lone Star Geyser: Hiking isn’t the only way to reach it. Bikes are also permitted on the flat, 2.5-mile path (a former road now closed to auto traffic). So if you happen to have a bike strapped to your car, you can accelerate your trip along the Firehole River to this wondrous geyser, which erupts every three hours and shoots a 40-foot fountain of water. That’s less dramatic than Old Faithful—but the relative lack of crowds makes this one of the most satisfying geyser experience in Yellowstone.
