Subway Cave – A Winter Adventure

Twenty thousand years ago and just 15 miles north of Lassen Volcanic National Park, the ground broke apart and huge volumes of volcanic rock poured forth to create the enormous expanse that is the Hat Creek Lava Flow.

Exposed to the air, the top of the lava flow began to cool and solidify, while molten rock below continued to flow – insulated by the now solid roof and creating lava tubes which carried the red-hot rock miles from its source.

Subway Cave is a section of lava tube less than a third of a mile long, located between two areas of ceiling cave-ins. Substantial concrete steps have been constructed at both ends of the cave, providing easy access for all would-be spelunkers.

My daughter going into the darkness of the cave for the first time, a little scary, and very exciting.

We had a big adventure visiting the Subway Cave last Saturday. I had seen it during summer, along with tons of other people. It’s a popular place during the summer months. (It’s easy accessible, and near a campground.) It’s definitely more of an adventure during winter. We didn’t see any other people, and no other vehicles at the parking lot. It’s pitch dark down there, so flash lights is a most if you want to go yourself.

Since we didn’t see any vehicles at the side of the road, or at the parking lot, it was safe to assume that we weren’t going to run into anyone. My dog enjoyed the adventure tremendously!

Light at the end of the tunnel – Stairs leading up towards the exit. You can turn around and go back the same way you came, if you want, but the views outside are gorgeous. There’s a nice trail making a loop around the cave, that will take you back to the parking lot. ย

Itโ€™s all about experiences, and the healing power of nature. Life is about choosing happiness. I entered the magic world of photography when I was five years old. My gypsy soul have taken me to many different countries, and definitely taught me to be more humble. I believe that you are what you eat, body and soul. I enjoy growing my own food, and spending time outdoors. Above everything else is my daughter. A Sagittarius loves to travel, have an open mind and, and a philosophical view. It motivates them to wander around the world in search of the meaning of life. Sagittarius is extrovert, optimistic and enthusiastic, and likes changes. A lot of that perfectly describes me. The fact that my ancestors, on both parents sides, were vikings, doesnโ€™t exactly lessen my desire to explore. Maybe a slightly more mindful exploring, compared to the average viking. My blog, and my art prints is a results of my (inner and outer) explorations. Love, Maria

    1. Definitely worth a visit, any season. It’s close to both Lassen Volcanic National Park, and Burney Falls, both magical places, where you can rent a simple cottage if you want to stay the night.


  1. Thanks for this one. Something I’d genuinely like to see. This is a belated thank you for following Under Western Skies … I’m finally catching up. After 24 years in California, I made it to the northern part of the state for the first time — Eureka, Redwoods and that area — and I’m eager to see a lot more. Happy writing.

    1. My pleasure, I’m so happy you enjoyed the post. Subway Cave is a special place, and it’s close to Burney Falls (amazing!!) Potem Falls (my daughter calls this waterfall the home of the fairies..I understand why..) and Lassen Volcanic National Park – lots of interesting places to visit if you’re in the area ๐Ÿ™‚ I love all the western states, and consider them my home now. I’m originally from Europe. Happy Writing!


  2. Wow, this is so cool! Lassen is fairly close, it would be amazing to see this. I’ve been to Lassen twice but never really stopped long enough to explore. Thanks for the great idea and amazing photos! We did get to walk through one of the Kilauea lava tubes in Hawaii a few weeks ago.
