AdventureUnderground

Get ready for an underground adventure and head down into an abandoned Victorian slate mine to find the remote, off-grid Deep Sleep camp. Located 420 meters beneath the mountains of Snowdonia, it's the deepest underground sleep experience in the world!

During your one-hour descent through ancient stairways, decaying bridges, and scrambles, your instructor will share fascinating historical facts about the area. When you'll arrive at the big steel door you'll know you have arrived at the Deep Sleep.

Behind the doors you'll find cozy cabins with double beds. Adventurer-expedition-style meals will be provided so you can replenish your energy before retiring to bed for the deepest sleep you ever had.

Your insctructor will stay on site so there's nothing to worry about. Breakfast is provided before heading out to surface. Also, there is Wifi available and basic toilet.

Worth it!
