While most people are preoccupied with what’s happening above ground in the Mount Shasta area, very few people think to venture underneath it. With towering mountains, epic hikes, cascading waterfalls, and incredible views, this oversight could be forgiven.
However, if you are looking for a smaller hike that delves into a darker side of the mountain, why not try Pluto’s Cave?
Pluto’s cave is a stunning collapsed lave tube, with Mount Shasta as a backdrop. After a very short hike through the desert, you can actually venture inside the cave and experience this slice of natural history.
This lesser-known cave lies on the north side of Mount Shasta, and if you are preparing to travel a long way into the cave, it is not a hike for those scared of the dark. There are a few cave-ins along the first stretch of the cave, which lets a little light in, but after that, you can journey for over a mile in the dark, and with no exit, you will have to be prepared to turn around and make your way back.
Exploring Pluto’s Cave
Pluto’s Cave was created due to a collapsed lava tube. It is roughly 190,000 years old—Old, even for a lava tube! One of the reasons for its long existence could be down to its location in a semi-arid environment, which means limited erosion and longer life. It has been named after Pluto, the Greek god of the underworld, which we think is quite fitting.
Here’s everything you need to know about exploring this magnificent wonder, which is one of our favorite things to do Mount Shasta!
How to Get to Pluto’s Cave
Although seemingly in the middle of nowhere, Pluto’s Cave is just a 30-minute drive from Mount Shasta Town, making it an easy half-day trip. It’s a nice drive, as you will have views of Mount Shasta along the route.
Start your drive from downtown Weed and head north on Highway 97. After 12 miles, turn left to County Road A12 for just over 3 miles. There is a turning left again, although it is hard to spot, and proceed to the trailhead along a dirt road; keep an eye out for the tiny sign for Pluto’s Cave. This point will take you there.
Pluto’s Cave Trail
The trail isn’t really a trail, but it does give you a nice opportunity to venture the 1200 feet into the accessible part of Pluto’s Cave. Start heading west from the trailhead, cutting through a high desert environment.
Although there is not much to see in your immediate environment, the Klamath Mountains stand proud in the distance, and towering Mount Shasta sits to the south. At this part of the hike, you will walk along a dusty wide path surrounded by a range of desert shrubs. After about a quarter of a mile, you will hit Pluto’s Cave.
You may only notice the cave due to portions collapsing, exposing the open channel and inviting you inside. As soon as you reach the end of the trail above ground, trail markers indicate you are to descend into the rocky mouth. It is now time to delve into the darkness.
The cave, at this point, is only accessible for about 70 to 80 feet, but you are not done yet. Climb back out of the cave, continue following the path north, and pass under a large archway.
Getting Further into the Cave
You will know that you have arrived, as the entrance to the cave is large and very, very dark. This is where your headlamp comes in. Even if the temperature is boiling outside, the temperature inside the cave stays at around the high 40s.
Once inside the cave, it is pitch black. There is a rough trail to follow, but there is nowhere else to go but forward. Follow the rocky ground, and soon you will find yourself on the sandy floor of Pluto’s Cave. This is where the most famous section of the trail can be found. A small section of the cave’s roof has caved in, allowing a beam of light to puncture the darkness and light up the cave’s floor.
You can continue on past this point for a while with another small caved-in section. After this, you can descend into the darkness of Pluto’s Cave with no further openings. The cave continues for about another mile, but it will be in pitch blackness, so if you are up for it, expect a very dark and rocky journey.
Once you reach the point where you can’t continue anymore, you will have to turn back and make your way back the way you came to get back to the parking lot.
TIP: You might want to use Maps.Me for this trail, this is what I used and it helped us a lot. We found people in the parking lot who got lost and never found the cave! So this spot is not as obvious as you’d think.
Tips For Visiting Pluto’s Cave
- Make sure you wear proper footwear, not just sandals or flip-flops, as the terrain is rocky and uneven. This can be particularly hazardous in the dark, so you need shoes with a strong grip and ankle support.
- Bring layers, such as a jacket or a sweatshirt, even if it is hot outside. Inside the cave, there is a notable temperature drop, and even in the summer, it can be chilly once you are underground.
- Bring a headlamp with you. This is a must, as there the no lights within the tunnel, so the trail will only be as light as you make it. You are entirely underground at this point, and the darkness is intense. If you don’t have one, you can still wander around the cave openings safely since there’s plenty of light there.
- As you walk towards the caves, keep an eye out for snakes. You will unlikely see them, but they have been spotted on the trail, so this is something to be aware of.
- Leave no trace. Like all trails in the great outdoors, don’t leave any sign that you have been there. Unfortunately, some people have taken it upon themselves to graffiti in the cave and use it as a bathroom too, so don’t be one of those people.
- The caves have susceptible ecosystems, so don’t bring any food or drink inside the cave. Smoking, pets, and fires are also not permitted.
