The land around this park.

Explosive eruptions formed a huge caldera, later partly filled by lava. Underground heat warms water circulating through fractures; different plumbing produces hot springs, geysers, mudpots and steam vents.

Before you set out.

Use the official NPS information to confirm the route you intend to walk, current closures, weather, and any access or permit requirements. A listing here does not confirm that a trail is open today.

Distances refer to the route type shown above. For a point-to-point route, plan how you will return; a trail network may offer several possible walks.

Carry the maps and supplies appropriate for your trip. Follow posted signs and park guidance; this overview is not turn-by-turn navigation.
