Fodor's Expert Review Boiling Springs Lake Trail

This worthwhile 3-mile loop leads from the Warner Valley Trailhead to Boiling Springs Lake, which is surrounded by high bluffs topped with incense cedar, Douglas fir, and other conifers. Vents beneath the milky gray-green lake release bubbles into it, heating it to a temperature of 125°F. Most who come all the way to Warner Valley combine this hike with one of the others that it connects with, typically either Devils Kitchen or Terminal Geyser. Easy–Moderate.
