Regional Map of Park
Lassen Volcanic National Park offers over 150 miles of hiking trails for visitors of levels of ability. Discover the devastation of Lassen Peak's last eruption on the accessible trail at the Devastated Area, explore Lassen's largest hydrothermal area on the Bumpass Hell trail, or spend the day climbing Brokeoff Mountain and enjoy its spectacular panoramic views. Please note that winter conditions often persist late into the summer months, and many trails are not snow free until June or July. View current trail conditions below or call (530) 595-4480 for the most up-to-date information.

Ground in hydrothermal areas can look solid but may actually be a thin crust hiding pools of acidic boiling water or mud. Traveling off-trail in these areas may result in severe injury.
