Skeleton Cave is a remarkable lava tube nestled within the vast Deschutes National Forest in Deschutes County, Oregon. Situated on the northern flank of the Newberry Volcano, near the vibrant city of Bend, this ancient natural monument offers a unique glimpse into the region's geological past. Formed between 75,000 and 400,000 years ago, this extensive cave system, with an elevation of approximately 1280 meters, is a testament to the powerful volcanic forces that shaped the Pacific Northwest.
What truly captivates visitors to Skeleton Cave is the opportunity to explore a well-preserved lava tube, revealing fascinating geological features like delicate "lavacicles" adorning its ceilings. The cave's constant cool temperature and unique environment provide a tangible link to ancient ecosystems, with the famous "Bear Passage" having yielded numerous Pleistocene animal remains, including those of dire wolves and North American short-faced bears. It's an educational and adventurous experience, particularly appealing for those interested in geology and paleontology.
Before planning your visit, it's important to know that Skeleton Cave is closed to the general public to protect its delicate ecosystem and resident bat populations. However, guided tours are available through authorized operators, providing a semi-wild caving experience. Participants are typically equipped with essential gear like helmets and headlamps. Given the cave's consistent internal temperature of around 44 degrees Fahrenheit (7 degrees Celsius), even in summer, dressing in warm layers is highly recommended to ensure a comfortable exploration.
While the cave itself maintains a stable climate year-round, the best season to visit the surrounding Deschutes National Forest area for other outdoor activities often aligns with spring through fall. Guided tours offer the primary way to experience the unique geological features within Skeleton Cave. These tours provide an immersive adventure, allowing visitors to navigate the cave's passages and learn about its natural history, making it a memorable outing for those seeking unique natural features.
Inside the cave, explorers can marvel at the intricate lavacicles and ponder the history of the animal bones found in areas like the Bear Passage. The skylight entrance, which once acted as a natural trap for animals, adds to the cave's mystique. Hikers and nature enthusiasts often combine a visit to the cave's entrance area with other Skeleton Cave trails and routes in the surrounding Newberry Volcano region, enjoying the diverse landscapes of the Deschutes National Forest.
Many visitors share their awe at the sheer scale of the lava tube and the feeling of stepping back in time. The discovery of ancient animal remains, some from species significantly larger than their modern counterparts, leaves a lasting impression. The quiet, cool atmosphere inside the cave, punctuated by the drip of water and the beam of headlamps, creates a truly unique and immersive experience that stands out from typical outdoor adventures.
While direct public access to Skeleton Cave is restricted, the surrounding area offers numerous opportunities for outdoor activities. You can explore various hiking and cycling routes that wind through the beautiful landscapes of the Deschutes National Forest.
