When’s the Best Time to Visit Lassen National Park?
California isn’t lacking when it comes to scenic stops – and one of my favorites to stop by anytime I’m in the Shasta Cascade region is Lassen Volcanic National Park.
Lassen gives you the best of both worlds for outdoor exploring. In the summer, you can access most of the park and see the area in its full volcanic glory. But the winter brings a unique take on the region – with a beautiful California snowpack inviting you to snowshoe a volcano (the perfect experience for your next party icebreaker!)
I have been lucky enough to visit in both seasons. While I enjoyed both my visits, there are significant differences to what you can experience depending on what time of year you are there.
So, when’s the best time to visit Lassen National Park? Here’s a hint: anytime.
But for those who are looking for the best that the park has to offer, you’ll want to aim for a sweet spot in late summer/early autumn. Let’s explore why.
Visting Lassen in Winter
Visit for the… best outdoor snow activities.
Winter turns Lassen into a snow-lover’s dream. Nearly 30 feet of snow can fall in the area, making it perfect for a variety of outdoor adventures.
The Manzanita Lake and Southwest Areas are open during the winter months, but you’ll want to have tire chains and a packed emergency kit if you plan to venture too far in. But once you arrive, you can take a ranger-led snow hike, cross-country ski, and even snowshoe a volcano.
The winter season arrives with the first snowfall, which will determine when the roads close. Typically winter in Lassen is from November through March, but don’t be surprised if snow comes as early as October or even late September. Expect lows in the teens and twenties, with highs in the forties.
If you can brave the cold, it’s worth the adventure. The scenery is incredible.
Visiting Lassen in Spring
Visit for the… lowest number of visitors.
Spring is when the snow starts to melt, and you’ll find that a good portion of the park is still closed down due to inclement weather conditions. Some spots are still accessible – such as the northwest and southwest park entrances – but most winter activities will wind down with the melt.
Spring in Lassen typically lasts from March through May. Expect temperatures of lows in the mid-twenties with highs reaching the low fifties.
But if you are looking to get away and avoid the crowds, spring isn’t a bad time to visit!
Visiting Lassen in Summer
Visit for the… most popular Lassen National Park experience.
Summer is the busiest season for Lassen. The main roadway through the park is fully open (barring any wildfire shutdowns), and you can access pretty much all of the area. Campgrounds are open, lakes are cold but swimmable, and the wildflowers are in full bloom.
A typical Lassen summer is June through August with lows in the mid-forties reaching highs up to mid-seventies.
Bumpass Hell Trail opens in late July once the snowpack offers access, but you’ll be fighting the crowds who are traveling through. So explorer, beware if you’re looking for some isolation in the outdoors.
Visiting Lassen in Fall
Visit for the… perfect weather, activities, and total park access.
If I had to pick the perfect time to visit Lassen National Park, I’d have to say the turning of the seasons from summer into fall. There’s something about having full access to the park without the sometimes oppressive heat that comes with summer.
Early fall is the only time that you’ll be able to get to the trails at higher elevations, as late summer sees the final bit of snowmelt needed to get there. Oftentimes, this is the only time you will be able to access the iconic Bumpass Hell if road conditions delay its opening.
Plus, you’ll still have the wildflowers blooming along the way. And with a slight fall breeze, you’ll get a hint of the coming winter while still being able to break a sweat along the trail.
Fall in Lassen is a small window in September and October, although it can be easily cut short if snow comes early. Lows fluctuate in the thirties and twenties, while highs can still reach the seventies.
Final Thoughts
Whether you go in the winter or summer (or that sweet spot in early fall), Lassen is one of the hidden gems of the Shasta region. I’ve covered my adventures in Lassen in other blogs – including how to get the most out of your snowshoe hike through a volcano!
