Lassen Volcanic National Park is a hidden gem among the many national parks in the United States. It is home to various types of volcanoes, making it a unique destination for nature enthusiasts and adventure seekers. The best time to visit this park depends on what you are looking for and what activities you want to do. Let’s look at what each season offers and why July is the ideal month for your adventure.

Spring (April – June)

Experience: Spring in Lassen National Park is a time of transition. Snow still blankets much of the park, especially at higher elevations, but the lower areas begin to thaw, bringing wildflowers and rushing waterfalls. Roads and trails gradually open up, but many remain closed due to snow.

Best Activities:

• Snowshoeing and cross-country skiing: Early spring is perfect for winter sports enthusiasts. The park’s snow-covered landscapes offer a serene experience.
• Bumpass Hell Trail: Typically accessible by late June, this trail leads to the park’s largest hydrothermal area, featuring boiling springs, mud pots, and fumaroles.

Our June Experience at Lassen Volcanic National Park

We were excited about our early June visit to Lassen Volcanic National Park. Our expectations included seeing geothermal features similar to what we witnessed in Yellowstone National Park. However, a few days before our planned visit, we checked the National Park website and learned we would have to change our plans. The park’s southern entrance was closed as four feet of snow still covered much of the area, including the popular geothermal features section. As a result, we shifted our plans to focus on the park’s north side. Even though the road inside the park was not fully open, we found enough to see and do for several days.

What’s Not Available:

• Highway 89, the road through the park, is often closed until late May or early June due to snow. This limits access to many areas and trails.

Summer (July – September)

Experience: Summer season is the most popular time to visit Lassen Volcanic National Park.  If you are interested in exploring the lower elevations of Lassen Volcanic National Park, plan your visit during the summer months. This is when most of the snow has melted.  The southwest entrance is most likely open by late June, providing access to trails and hot springs. By July, the park is fully accessible, with all roads, trails, and facilities open. The warm weather makes it the perfect time for hiking, camping, and exploring the park’s geothermal wonders.  Additionally, this is the peak season for camping at Manzanita Lake Campground, a popular spot for visitors to stay and enjoy the stunning views of the surrounding landscape. 

Best Activities:

• Lassen Peak Trail: This is the best time to hike to the summit of Lassen Peak. The 5-mile round trip offers panoramic views and a close-up look at the volcanic terrain.
• Kings Creek Falls: A popular hike in July, this trail leads to a stunning waterfall surrounded by lush greenery.
• Manzanita Lake: Ideal for kayaking, canoeing, and photography, especially with the reflection of Lassen Peak on the lake’s surface.
• Cinder Cone: Explore this fascinating volcanic feature, which is most accessible in the summer.

What’s Not Available:

• Summer brings the risk of wildfires, which may lead to air quality issues and potential area closures.

Fall (October – November)

Experience: Fall is a quieter time at Lassen Volcanic National Park. The crowds thin out, and the autumn colors start to appear. The temperatures cool down, making it comfortable for hiking and exploring.  Visiting Lassen Volcanic National Park during the fall shoulder seasons is recommended for those seeking a more challenging adventure. During this time, you can still access some of the higher elevations and witness the spectacular scenery while avoiding the crowds that come with peak season. 

Best Activities:

• Autumn foliage hikes: Trails like those in the Manzanita Lake area and Summit Lake Loop offer beautiful fall colors.
• Hydrothermal areas: With fewer visitors, you can enjoy places like Sulphur Works and Bumpass Hell in relative solitude.

What’s Not Available:

• By late October, snowfall can start to close roads and trails, limiting access to higher elevations.

Winter (December – March)

Experience: The winter season transforms Lassen Volcanic National Park into a snowy wonderland. The park is a destination for winter sports, with activities like snowshoeing and backcountry skiing. Winter presents the park in its most quiet and peaceful state. The main park highway is closed during this time, but you can still access various areas through snowshoeing or cross-country skiing. 

Best Activities:

• Snowshoeing: Explore the park’s snow-covered landscapes on snowshoes. Popular routes include the Sulphur Works and Manzanita Lake areas.
• Snow camping: For the adventurous, winter camping offers a unique experience in the park’s quiet and serene environment.

What’s Not Available:

Risks When Visiting Lassen Volcanic National Park

Lassen Volcanic National Park’s dynamic environment presents certain risks that visitors should be aware of:

• Wildfires: Summer and early fall are wildfire seasons in Northern California. Wildfires can lead to air quality issues, road closures, and evacuations. Always check for fire alerts before your visit.
• Snow and Road Closures: From late fall through spring, heavy snowfall can close roads, including the main park road, Highway 89. Visitors should be prepared for harsh winter conditions during the winter months and check the park’s website for current road status.
• Volcanic Activity: While Lassen Peak last erupted in 1917, the park is still an active volcano area. Visitors should stay on designated trails in hydrothermal areas and know the potential for sudden geothermal activity.

If you’re planning your first visit to Lassen Volcanic National Park, it’s essential to be prepared for the high altitude. The park’s elevation ranges from 5,000 to over 10,000 feet, which can impact your body. Bring plenty of water and take breaks as needed to acclimate.

It’s always a good practice to check the park’s website for current conditions before you visit.
