What to Expect

Starting from the Warner Valley trailhead, this three-mile round trip follows a mostly flat path through a landscape still bearing the scars of the 2021 Dixie Fire — standing snags, blackened trunks, and the first stubborn wildflowers pushing through ash-enriched soil. The lack of tree canopy means you're fully sun-exposed for nearly the entire hike, which makes it feel longer than it is on a hot day. But the payoff is worth every bead of sweat: Boiling Springs Lake is a surreal, steaming cauldron of milky turquoise water ringed by bubbling mud pots and hissing fumaroles. The sulfur smell hits you before the lake does. The trail surface is generally well-maintained dirt and boardwalk near the thermal features, making it manageable for kids who can handle a moderate distance. This one's perfect for families who want to show their children that Yellowstone isn't the only place where the earth tries to cook itself.

Safety Advisory

Thermal ground near the lake is genuinely dangerous — stay on boardwalks and marked trails at all times. The crust around geothermal features can be paper-thin, and the water beneath is hot enough to cause severe burns.

With the post-Dixie Fire canopy gone, there is zero shade on this trail. Heat exhaustion is a real risk in summer — carry more water than you think you need and wear sun protection.

Pro Tips

Trail Tip

Start early morning — by midday the exposed trail becomes a sun trap, and the thermal features photograph better in low-angle light when the steam really billows against a darker sky.

Trail Tip

The Warner Valley trailhead is at the end of a rough, unpaved road that adds thirty-plus minutes to your drive; don't rely on GPS arrival times, and make sure your vehicle can handle washboard gravel.

Trail Tip

Linger at the mud pots on the lake's southeast shore — they're easy to miss if you beeline for the main overlook, but the gurgling, popping mud is the most mesmerizing feature on the entire trail.
