1 Best Sight in Mineral, The Far North

Sulphur Works Thermal Area

Proof of Lassen Peak's volatility becomes evident shortly after you enter the park at the southwest entrance. Sidewalks skirt boiling springs and sulfur-emitting steam vents. This area is usually the last site to close in winter, but even when the road is closed, you can access the area via a 2-mile round-trip hike through the snow.
