Lassen Volcanic National Park gears up for Summer 2025: What to know about reservations, services, and closures
Lassen Volcanic National Park is actively preparing for its summer 2025 season, though significant snow currently impacts the main park highway and popular trails, with clearing operations underway.
As the snow begins its slow retreat from the higher elevations, Lassen Volcanic National Park is steadily preparing for its summer 2025 season. Visitors planning to explore the park's remarkable hydrothermal features, clear mountain lakes, and volcanic peaks should anticipate a mix of exciting opportunities and necessary precautions.
Here’s an update on what to expect regarding reservations, available services, and current road and trail conditions.
Current Park Status and Road Access
Spring snow clearing is a significant undertaking at Lassen. As of May 8th, 2025, the Lassen National Park Highway (Hwy 89) remains partially closed.
Vehicle access is currently blocked at Sulphur Works from the southwest entrance and at the Devastated Area from the northwest entrance. However, the road beyond these closures is open for pedestrian and bicycle use. Visitors choosing to walk or bike should exercise extreme caution, be aware of snow and ice, and remain alert for ongoing snow plowing operations. Park officials urge visitors to maintain a safe distance of at least 100 feet from all plowing equipment.
Historically, the full opening of the 30-mile Lassen National Park Highway, which traverses many of the park's main attractions, can occur anytime from late May to mid-July, depending on the winter's snowfall. Visitors should regularly check the park's official website for the most up-to-date road status before planning their trip.
Other park roads, including those leading to Juniper Lake, Butte Lake, and Warner Valley, also experience seasonal closures due to snow. Updates on their status will be provided as conditions allow.
Popular Trails and Attractions
Many of Lassen’s iconic trails are still under seasonal snow. Notably, the Bumpass Hell Trail is currently closed due to significant snow accumulation. This popular trail, leading to the park's largest hydrothermal area, typically remains closed until early July to ensure visitor safety from treacherous conditions near boiling mud pots and fumaroles.
While some lower elevation trails may be accessible, hikers should be prepared for lingering snow patches, wet and muddy conditions, and potential hazards from the 2021 Dixie Fire.
Summer attractions visitors can look forward to (once accessible) include:
- Sulphur Works: The park's most easily accessible hydrothermal area, often one of the first to be clear of snow near the southwest entrance.
- Manzanita Lake: Known for its stunning views of Lassen Peak, offering opportunities for kayaking, hiking, and photography. The Manzanita Lake Camper Store and Camping Cabins are scheduled to open for the season starting May 22, 2025.
- Lassen Peak: The park's namesake volcano. The trail to the summit typically holds snow well into the summer.
- Lake Helen: A picturesque high-elevation lake.
- Kings Creek Falls: A beautiful waterfall accessible via a moderate hike.
- Devastated Area: Offers an interpretive trail showcasing the impact of Lassen Peak's 1915 eruption.
Reservations and Camping
Lassen Volcanic National Park does not require a reservation for park entry, though an entrance fee is applicable.
However, reservations are highly recommended for camping. Most campgrounds in the park, including Manzanita Lake, Summit Lake, and Butte Lake, require reservations, which can be made through Recreation.gov. Limited first-come, first-served camping is available at Juniper Lake, Warner Valley, and the Southwest Walk-in campground. Given the park's popularity and limited cell service, securing reservations well in advance is strongly advised.
The Manzanita Lake Camping Cabins also require reservations and are set to open on May 22, 2025. Drakesbad Guest Ranch, located in the Warner Valley area, also operates on a reservation system.
Park Services
Visitor Centers: The Kohm Yah-mah-nee Visitor Center, located near the southwest entrance, is generally open year-round, though services might be limited in the early season. The Loomis Museum, near the Manzanita Lake entrance, typically opens for the summer season later in spring or early summer. Check the park website for current operating hours.
Food and Supplies: The Lassen Café and Gift store within the Kohm Yah-mah-nee Visitor Center offers food options. The Manzanita Lake Camper Store provides groceries, supplies, gifts, and gasoline from mid-May through mid-October.
Gasoline: Unleaded gasoline is available at the Manzanita Lake Camper Store during its operational season. There are no other gas stations within the park.
Water: Potable water is available at visitor centers and developed campgrounds.
Cell Service: Visitors should be aware that cell service is very limited and unreliable throughout the park. It's recommended to download any necessary maps or park information before arrival.
Dixie Fire Impacts and Safety
The lasting effects of the 2021 Dixie Fire continue to impact some areas of the park. While many areas have reopened, visitors must adhere to all closure signs. Hazards such as fallen trees, loose or falling rocks, undefined trails, and hidden stump holes exist in burned areas. Always stay on marked trails and be aware of your surroundings. Information on burned area safety is available on the park's website.
