Lassen Volcanic National Park Trip Planner
Tell us how long you have, who's along, and the season. We'll group it by region so you drive less and see more.
Day 1 Manzanita Lake (northwest)
-
Manzanita Lake
A reflective lake at the northwest entrance that mirrors Lassen Peak on a still morning — an easy shoreline loop, a swimming and paddling spot, and the park's other year-round base. Reachable when the high road is closed.
-
Loomis Museum
A small stone museum at Manzanita Lake built around B.F. Loomis's photographs of the 1914–1915 eruptions — some of the first close images ever made of an erupting Cascade volcano. Open in the summer season.
Day 2 Park Highway high country
≈50 min drive from Manzanita Lake (northwest)
-
Bumpass Hell
The park's largest hydrothermal basin — a boardwalk winds through acres of boiling springs, fumaroles, and mudpots reached by a moderate trail off the high road. Snow buries the trail into July.
-
Lake Helen
A deep, cold snowmelt lake at about 8,200 feet on the high road, ice-blue and often ringed by snow into midsummer, with Lassen Peak above it — a roadside stop for the view.
-
Devastated Area
A short paved interpretive loop through the blast zone of the 1915 eruption, where the mountain sent a mudflow and pyroclastic flow down this slope. Signs explain how the forest is coming back.
Day 3 Southwest Entrance & Sulphur Works
≈50 min drive from Park Highway high country
-
Kohm Yah-mah-nee Visitor Center
The park's year-round hub just inside the southwest entrance, its Mountain Maidu name meaning 'snow mountain.' Exhibits, a ranger desk, and food; in winter it's the base for sledding and snowshoeing when the high road is closed.
-
Sulphur Works
A roadside hydrothermal area a mile inside the southwest entrance — boiling mudpots and steaming ground right beside the highway, the easiest look at Lassen's volcanic plumbing. Stay on the boardwalk; the crust is thin.
If you have more time
Lassen Peak Trail
A steep switchbacking climb to the 10,457-foot summit of the volcano that erupted in 1914–1917, with views across the Cascades and, on a clear day, Mount Shasta. Loose rock and thin air; carry water and sun protection.
Cinder Cone & the Painted Dunes
A steep climb up loose ash to the rim of a symmetrical cinder cone, with the multicolored Painted Dunes and the Fantastic Lava Beds spread below. Reached from Butte Lake in the park's remote northeast on a gravel road.
