Visitor Centers

There is a visitor center just inside the northwest entrance at the Loomis Museum. The Loomis Museum (daily late June to late Sept) has interpretive exhibits, videos, and leaflets. Ranger-led walks are offered late June to early September.

Just inside the southwest entrance, the terrific new Kohm Yah-mah-nee Visitor Center features interpretive exhibits, a bookstore, and a cafe. Named for the Mountain Maidu people's moniker for "Snow Mountain," Kohm Yah-mah-nee is open daily year-round.

The park headquarters, on Calif. 36 in Mineral, southwest of the park, offers information and publications Monday to Friday (except holidays) year-round. There are ranger stations at Summit Lake and in the more isolated reaches of the park at Warner Valley, Juniper Lake, and Butte Lake.

Fees & Permits

Entry to the park for up to a week costs $10 per vehicle or $5 per person on foot, horse, or bicycle. Camping fees range from $10 to $18. Anyone spending the night in the backcountry must obtain a free wilderness permit.

Special Regulations & Warnings

Because of the dangers posed by the park's thermal features (specifically the boiling, acidic water), always remain on trails in active areas and heed warning signs. Fires are allowed in campgrounds only. Warm clothing is needed year-round.
