Lassen Volcanic National Park

Lassen Volcanic National Park in Northern California is a land of hydrothermal marvels like fumaroles, mud pots, and hot springs. Home to Lassen Peak, one of the largest plug dome volcanoes in the world, and the scenic beauty of the surrounding forests and clear mountain lakes, this park offers a fascinating glimpse into our planet's geologic power. Whether you're exploring its rugged terrain or learning about its role in the Cascade Volcanic Arc, Lassen Volcanic National Park provides a unique and compelling outdoor experience.

Geothermal Features

Bumpass Hell

One key destination for those interested in the park's geothermal activity is Bumpass Hell, where visitors can walk along boardwalks to explore an area dense with boiling springs and fumaroles. Named after an early settler who severely burned his leg here, Bumpass Hell showcases the park's volcanic nature vividly. Be sure to stay on the path, as the ground can be dangerously unstable and hot.

Sulphur Works

Another readily accessible hydrothermal site is the Sulphur Works, located near the main park road. This area features strong-smelling steam vents and mud pots, with the odor revealing the presence of volcanic gases just below the surface.

Hiking and Outdoor Activities

Lassen Peak Trail

For hiking enthusiasts, the Lassen Peak Trail rewards visitors with panoramic views from the summit of one of the park's most prominent volcanoes. This strenuous hike is best attempted in the summer months when the trail is mostly free of snow.

Manzanita Lake Loop

Less challenging but equally rewarding, the Manzanita Lake Loop is a leisurely trail suitable for all ages that offers stunning views of Lassen Peak and opportunities for photography, especially around sunrise or sunset.

Wildlife and Nature

The park's diverse ecosystems support various wildlife species such as black bears, mountain lions, deer, and a myriad of bird species. While hiking or camping, keep your distance from wildlife and store food properly to avoid attracting bears.

Visitor Facilities and Accessibility

The park operates a number of visitor centers, including Kohm Yah-mah-nee Visitor Center, providing educational displays on the area's natural history and information on current conditions. Most key attractions in Lassen Volcanic National Park are connected by a 30-mile highway that opens seasonally once snow is cleared.

Seasonal Weather and Best Times to Visit

The best time to visit the park is from late June to October when most snow has melted, and roads and trails are open. Winter brings heavy snowfall, transforming the park into a destination for snowshoeing and cross-country skiing, but also limiting accessibility.

Safety and Conservation

Due to its volcanic nature, safety is paramount. Visitors should heed warnings and closures, especially around geothermal areas. Remember to practice Leave No Trace principles to help preserve the park's pristine environment.

Educational Programs and Tours

Ranger-led programs offer insights into Lassen Volcanic National Park's unique features. These educational walks and talks often cover topics like the region's geology, ecology, and the impact of the 1915 eruption that reshaped much of the landscape.

Scenic Drives and Viewpoints

For those preferring to explore by car, the Lassen Volcanic National Park Highway offers numerous pullouts with interpretive signs and impressive vistas. Don't miss the Kings Creek Falls overlook or the Devastated Area interpretive trail which tell the story of past volcanic activity and its effects on the landscape.

The 1915 Eruption's Impact

Evidence of the 1915 eruption is visible throughout the park. The aforementioned Devastated Area shows how this event changed the topography, with regrowth still in progress a century later.

Camping and Backcountry Permits

The park offers a range of camping options from developed campgrounds like Manzanita Lake Campground to backcountry sites for those seeking solitude. Permits are required for overnight backcountry stays to ensure visitor safety and minimal impact on the environment.
