Permits:  A free permit is required to camp in the park backcountry (outside of Lassen’s developed campgrounds). You fill out your permit at the self-registration stations within the park and must include details such as your party size, entry and exit trailheads, approximate campsite location for each night, emergency contact information, and vehicle make, model, and license number.

Click here to read more about Logistics

Logistics: To access the Kings Creek Trailhead, you will need to drive along Highway 89. This road is closed for the winter and typically opens sometime between late May and July (deepening on winter snow levels). Be sure that the road is open when you plan to take your trip. If you would like to camp the night before your trip, Lassen Volcanic National Park has several developed campground you can stay at. Some sites are available on a first-come, first-served basis and some can be reserved on recreation.gov. Reservations are advised during busy summer weekends. For this specific itinerary, you park your car and start the hike at the Kings Creek Picnic Area Trailhead.

Trail Conditions and Difficulty: This itinerary within Lassen Volcanic National Park is of moderate difficulty. On average you will hike ~10 miles a day, but there is no particular day with extreme elevation gain. Also, on day 2 you do not need to pack up your camp and can just day hike to the Cinder Cone and back. Overall the trail is well marked. If hiking early in the season you may encounter snow on the mountain passes, so it is wise to check snow levels before setting off on your hike.

Supplies: There are active black bears in the Lassen Volcanic National Park, so you need to bring a bear canister to store food and scented items. Bear spray is not allowed so leave that at home.

You likely will want bug spray because the mosquitoes can be out in force in certain areas of the trek. I prefer a picaridin based spray because it does not damage plastics and synthetic fibers like high concentration DEET sprays can. I also like to pre-treat my clothes and tent with permethrin spray repellent. The permethrin treatment stays on your clothes for up to 7 washes, so it helps reduce the amount of spray you need to put on your skin.

Eventually you pass by Swan and Twin Lakes and finally reach Rainbow Lake shortly after the 10 mile mark. There are several nice campsites along the shore of Rainbow Lake.

Day 3 takes you back across Highway 89 to the Cliff Lake area. Along the way you pass several lakes including Twin Lakes, Echo Lake and Summit Lake. The trail moves in and out of the forest. After Summit Lake, you cross the highway and begin a 2 mile climb up to the meadow that sits to the east of Cliff Lake (the campsite for this night). Note that you are not allowed to camp within 0.25 miles of Cliff Lake, so make sure you stay far enough east of the lake to be within the rules. It is best to utilize the stream for water so that you do not need to hike back and forth to the lake.

On the final day of this itinerary, you begin by climbing west past Cliff Lake and Shadow Lake before reaching Highway 89 again. From there you hike along the road descending for 2.5 miles until you end up back at your car in the Kings Creek Picnic Area. Leave your heavy items in your car and then set off for a day hike to the Bumpass Hell hydrothermal area. It is roughly 3 miles to hike to the west end of Bumpass Hell and then 3 miles to retrace your steps back to your car.

    1. Hi Kim – So far, all indications I can find point to Lassen Nation Park being open for backpacking and backcountry camping this year. Let’s hope it stays the case, but there is currently no mention of camping closures on the park website.
