You can descend the staircase and look back at the cave entrance, lined with moss.\nFor Lord of the Rings nerds, it will feel like you're going into the Mines of Moria. Make sure to bring flashlights or even headlamps with you to make the most out of the hike.\nView this post on Instagram Spelunking under igneous rock 🌋 . . #apecaves #mtsthelens #washington #spelunking #taschenlampe #lightsout #cavemen A post shared by J.R.

You'll have to climb over boulder piles and scramble up a lava fall that's eight-feet-tall! Definitely bring sturdy hiking shoes, extra flashlights, and warm clothes with you on this hike.\nView this post on Instagram #apecaves A post shared by Denis Samoilov (@d.samoylov) on Jul 28, 2019 at 2:22am PDT\nYou're not allowed to touch the cave walls because the slime that lives on the walls is actually important to the ecosystem inside the cave, so you don't want to disturb their food source. Plus, you're not allowed to collect rocks or take anything home with you. So be aware of these notes if you decide to take on this spooky volcanic hike this fall.\nApe Caves\nPrice: Free!\nAddress: Ape Cave, Washington 98616, USA\nWhy You Need To Go: Explore eerie volcanic caves just over the border from Vancouver and spook yourself on this amazing hike!\nWebsite\n\n\n\n\nWe strongly advise that before you go swimming or visit any location, you check the most recent updates on potential hazards, security, water quality, and closures.
