A shot of the inside of the Ape Cave in Washington State, USA.Ape Cave. This natural wonder is not your average cave; it is the longest continuous lava tube in the continental United States, stretching over two miles in length. Imagine stepping into a world of darkness, surrounded by ancient lava formations that tell a story of the earth's fiery past. As you venture deeper into Ape Cave, the temperature drops, and the darkness becomes more enveloping. The eerie silence is broken only by the sound of your footsteps echoing off the walls, creating a sense of mystery and intrigue. Stalactites and stalagmites line the cave, formed over thousands of years by slow-moving lava that once flowed through this underground passageway.

Explorers of all ages can embark on this underground journey, equipped with sturdy shoes, a reliable light source, and a spirit of adventure. The cave offers two routes: the easier Lower Cave trail, suitable for beginners and families, and the more challenging Upper Cave trail, which requires climbing over boulders and navigating narrow passages. As you emerge from the depths of Ape Cave back into the daylight, you can't help but marvel at the unique experience you've just had. The cool forest air refreshes your senses, and the memories of your underground expedition linger long after you've left the cave behind. Ape Cave is not just a geological wonder; it's a testament to the power and beauty of nature that continues to captivate and inspire all who dare to explore its depths.

The guesthouse offers a great location for rest and relaxation as well as a “base camp” for recreational adventure expeditions.
