Flaming Geyser State Park

The Flaming Geyser State Park is located on the Green River in southwestern King County, Washington, near the city of Black Diamond. The park was named for a flame which burned through a concrete basin, fueled by a methane gas pocket 1,000 feet (300 m) below the surface. When the pocket was discovered by prospective coal miners in the early 1900s, the test hole hit gas and saltwater, shooting water and flames 25 feet (10 m) into the air.

The same methane pocket seeps gas through a mud hole to create the "Bubbling Geyser" nearby. Both "geysers" can be found along a short hike, though as of 2016 the flaming geyser is no longer lit due to depletion of its methane source. Despite these unique features, the most popular park use is for summer tubing and rafting in the river.

Flaming Geyser also has a specially designated area for flying remote-controlled model airplanes.

Flaming Geyser State Park occupies a particular place in the imagination of American public lands. As a State Park in Washington, it represents a deliberate choice — by the people who advocated for its protection, and by the National Park Service rangers who maintain it — to keep this landscape available to anyone willing to make the trip. That accessibility is the quiet miracle of the park system.

The pages linked below break the visit down into the four practical questions every traveler asks: where can I hike, where can I sleep, what else is worth seeing while I'm in the area, and what should I know before I show up. Each one is written from the perspective of someone planning their first trip — assume nothing, explain what's worth explaining, and skip the marketing language. If you've been here before, treat these guides as a refresher and a way to discover the corners you missed last time.
