Lassen National Park Attractions: Hikes, Lakes, Caves and Geothermal Areas

Lassen National Park is one of California’s most underutilized, due mainly to its location in Northern California, but it is also one of its most beautiful. This park has everything from subway caves and volcanic summits to geothermal areas and waterfalls. It is a must visit in California and here is a collection of the things you will see when you visit, based on entering from the southern entrance.

Visitor Center

Lassen 1

The visitor center is better than most national parks; it has a lot of park info, a gift shop and a decent cafe.

Lassen 2

The cafe has all the normal stuff like hamburgers, fruit, ice cream and sandwiches. It is a great place to have a meal after a day of hiking and it is good to have as there is no other food close.

Sulphur Works


Right up the road from the visitor center is a parking lot that leads to an easy to access geothermal area called Sulphur Works. This area is said to be the volcanic center of the ancient volcano, and from here you can walk to a bubbling mud pool with escaping sulfur mist that smells like rotten eggs. There are also some cool overlooks that show the color patterns that the gas has on the terrain.

Bumpass Hell


Much like the Sulphur Works, Bumpass Hell is an amazing geothermal area that requires 2.5 miles each way to get to it. This is one of the most strangely beautiful parts of the park, and a must visit if you can handle the hike. The area has massive mud boiling pots, sulfur steam vents and unique colored landscape with wooden plank walkways. Read my full post on it here.

Lake Helen


This lake is one of my favorite spots in the park. It is a simple turn off that has a beautiful vista of Mt Lassen with the pristine blue lake in front of it. I could spend a lot of time here, and I make it a stop on every trip to the park.

Mt Lassen Trailhead


Right after the lake, there is a parking lot for the trailhead to the summit of Mt Lassen. This is one of my favorite hikes in all of California but it is only open three weekends out of the year (open more now, this was from 2014) so if you want to hike it then make sure you research if it’s open. Check out my full post here.

Cold Boiling Lake

After you descend from the Lassen trailhead, there is a small turn off for King Creek. This is the parking lot for the trailhead to Cold Boiling Lake. This hike is relatively easy at around a mile each way, but at the end, you are dropped in a fantastic meadow that has mountains around it and a beautiful forest. The lake itself has small water runoffs around it where you can see the cold water boiling, or the sulfur bubbles escaping if you want to know what it actually is.

Kings Creek Falls

After the last turn out there is a stop for King Creek Falls a beautiful hike along a cascading river that ends at an incredible 40-foot waterfall. The hike is about 3 miles each way with 700 feet of elevation gain when coming back up from the falls, so make sure you are ready for it. It is an amazing view though and a great way to explore the backcountry areas of the park.

Subway Cave

Subway Cave 12

From here I haven’t stopped too much on the backside of the park, other than to exit the back and proceed slightly out of the park to a lava tube subway cave. While this is not really in the park, I felt it was good to mention since it is some close and so cool. From the parking lot, it is a short walk to the start of this amazing 1/3 of a mile lava tube.

As you can see from the above post, I love this park, it is incredible and has so much to offer. Get yourself up there and experience it for yourself. Feel free to leave a comment below.
