About Long Valley Caldera

Long Valley Caldera in eastern California offers a striking blend of natural wonders and soothing hot springs. This vast volcanic basin, formed by a massive eruption 760,000 years ago, hosts seven distinct hot spring pools where you can soak amid rugged geological beauty. The warm mineral waters provide a rare combination of volcanic history and aquatic relaxation.

Getting There

Access to the Long Valley Caldera hot springs involves a short walk ranging from 2 to 15 minutes from limited nearby parking. The paths are generally manageable but expect a bit of uneven terrain typical of volcanic landscapes. The springs are free to use, making them an inviting spot for those exploring hot springs in California.

What to Expect

The seven pools vary in temperature and size, with some offering intimate spaces and others more open. Water is warm and mineral-rich, set against the dramatic backdrop of the caldera’s rocky ridges. Facilities are minimal, so the atmosphere is natural and tranquil, though the area can attract crowds during peak seasons.

Tips for Visitors

Plan your visit during the early morning or later evening to avoid busier periods and enjoy a quieter soak. Bring sturdy shoes for the short walk and plenty of water, as facilities are basic. Keep in mind parking is limited and the springs have no entry fee, so arrive prepared to share the space with other visitors enjoying these unique California swimming holes.
