Although it is known and named as a geyser, the Terminal Geyser is more like a steam vent than a true geyser. That does not make it less impressive. To get here, you have to follow a narrow, sometimes not that obvious trail. You can even climb down all the way to the steam that reveals a certain smell like rotten eggs. Always be careful around hydrothermal areas!

"This moderately difficult section of the PCT takes one through one floriferous rock garden after another, interspersed now and again by shady, cool pine-fir forest. Every color of the rainbow was represented in these rock gardens, some of which were perched on hillsides, others on open ridgelines with expansive views." https://shasta-cnps.org/humboldt-summit-to-little-cub-spring-july-10-2022/

"For your safety, stay on established trails and boardwalks. Ground in hydrothermal areas can look solid but may actually be a thin crust hiding pools of acidic boiling water or mud. Traveling off-trail in these areas may result in severe injury. Read more about exploring the park hydrothermal areas." https://www.nps.gov/lavo/planyourvisit/hiking_terminal_geyser.htm

Spectacular views of Long Lake and the entire Lakes Basin area can be had throughout this entire section of trail. The western section of trail is higher up from the lake and offers spectacular views of the surrounding area. As you get closer to the lake be sure to check out the crystal clear water and soak your feet after a long day of hiking.

Take the loop or hike at least along the east side of the pond. Here are the most existing geothermal activities like bubbling mudholes and steaming soil. The mudholes are not visible from the west shore.

There is lots of space for tents around Boundary Spring - however this is a very badly burned area with lots of dead trees that will fall itself or you might be hit by falling branches. My advice to reduce the risk: Get your water from the spring, hike on into Lassen National Park for ~ 0.2 miles, turn left onto the Willow Lake Trail, follow the faint trail for another ~ 0.3 miles to the trailhead. There is room at the dead end and you will be outside the park boundary again.

Lookout Spring is a reliable water source close to Lookout Rock. The water flows out of a pipe and is ice cold. Enjoy!

Rattlesnake Spring is a pretty reliable water source with clear, cold water. There was no rattlesnake present when I filled my water bottles though.
