TrailAvalanche Peak Trailhead 5N2
4.5-mile out-and-back; 2,100 ft gain. Relentless climb with a true summit payoff.

This short boardwalk trail in Yellowstone's Lower Geyser Basin serves up all four types of hydrothermal features—geysers, hot springs, mudpots, and fumaroles—in just 30-45 minutes. The verdict: Easy distance, but thermal hazards demand constant attention. Readers will see churning mudpots, erupting geysers, and steaming vents. Expect crowds mid-morning; the payoff is compact geothermal spectacle accessible to most fitness levels.
Easy
See all four major types of hydrothermal features in a compact boardwalk route
• Arrive by 7:30 AM to beat the mid-morning parking crunch • Fountain Paint Pot itself—the mudpot namesake—is the centerpiece; don't miss the far overlook near Twig Geyser • Visit in early evening for thinner crowds and better light for photos • Thermal steam intensity changes seasonally; observe behavior carefully
