Whether you’re looking for an underrated national park to visit in Northern California or things to do outside in Northern California, you won’t be disappointed with Lassen Volcanic National Park. There are so many people who know and love the park that it is hard to call it underrated, but if you compare it to the much more popular parks in the state, like Yosemite and Death Valley, you'd be amazed at the relative lack of crowds. However, don’t assume that crowds are an indicator of a park’s worthiness because, even though Lassen Volcanic National Park is crowd-free, it’s easily one of the best parks in Northern California.

The park is home to active volcanoes and hot springs that are available to see year-round. With more than 150 miles of trails, it's great for avid hikers.

The most iconic landmark of the park is Lassen Peak, the largest plug dome volcano in the world and the southern-most volcano in the Cascade Range.

The peak and surrounding mountains are visible from miles and miles away. Pictured here is Lassen from Lake Alamanor.

Brokeoff Mountain, which was once known as Mt. Tehama before the volcano erupted, sits just to west of Mt. Shasta. At one point in time, it was 1,000 feet higher than Mt. Shasta.

The park is one of the few places in the world where all types of volcano (plug dome, shield, cinder cone, and strato) can be found.

Chaos Crags are another interesting and prominent landmark in the park.

The painted dunes are desolate but beautiful. They're also among the many unique vistas to take in at Lassen Volcanic National Park.

The Caldera Rim of Cinder Cone is another remarkable landmark. Cinder Cone and the Fantastic Lava Beds are about 10 miles northeast of Lassen Peak. This is the site of a cinder cone volcano and associated lava flow field that last erupted about 1650. It created a series of basaltic andesite to andesite lava flows, which have come to be known as the Fantastic Lava Beds.

Sulphur Works is a geothermal area between Lassen Peak and Brokeoff Mountain. It's thought to mark an area near the center of Tehama's now-gone cone.

There are many hot springs and geysers within Sulphur works to check out, including this one called the Mudpot.

Be sure to stay on the path and boardwalks, like this one at Bumpass Hell. The temperatures of these waters are scalding and potentially life threatening.

Lake Helen is just another of the incredible vista points, and a great place to snowshoe or Nordic ski in the winter. The snow melt is just breathtaking.

In addition to the unique volcanic landscape of this park, there's breathtaking alpine beauty.

It's located at the southern end of the Cascade Mountain range and is sure to take your breath away.

Snow enthusiasts and skiers are sure to love a visit here. This is Lassen peak up-close-and-personal in the winter.

The Sulphur works are also striking in the snow!
