Oregon, a state nestled in the Pacific Northwest region of the United States, is celebrated for its diverse and magnificent natural beauty. From pristine coastlines and lush green forests to snow-capped volcanoes, Oregon is a dream destination for those who love to explore. Beyond its well-known landscapes, Oregon also conceals a wondrous underground realm with unique natural tunnels, waiting for adventurous footsteps.
If you are an adventure enthusiast seeking extraordinary experiences, exploring the natural tunnels in Oregon is definitely an unmissable journey. These geological wonders, formed over thousands of years by volcanic activity and natural erosion, offer a pristine, mysterious, and challenging beauty. This article will take you on a journey to discover the most beautiful natural tunnels in Oregon, while providing useful information for a safe and memorable trip.
Exploring Oregon’s Magnificent Underground World
Oregon boasts a rich system of caves and natural tunnels, diverse in shape and origin. Among them, the most prominent are lava tubes, formed from volcanic lava flows thousands of years ago. As the surface lava layer cooled and solidified, the molten lava underneath continued to flow, creating hollow tunnels beneath the ground.
Besides lava tubes, Oregon also has sea caves created by waves eroding coastal cliffs over long periods. These sea caves are typically located along the Oregon coast and possess a magical beauty, especially when sunlight shines inside, creating shimmering light effects.
However, this article will primarily focus on lava tubes, the most common and accessible type of natural tunnel in Oregon, offering unique and exciting exploration experiences.
Famous Natural Tunnel Exploration Destinations in Oregon
Oregon is a paradise for cave and natural tunnel exploration enthusiasts. Here are some famous destinations you shouldn’t miss:
1. Newberry National Volcanic Monument
Located in central Oregon, Newberry National Volcanic Monument is a vast area with distinctive volcanic landscapes, including the Newberry Caldera, Crater Lake, and especially a diverse system of lava tubes. It is one of the top destinations for exploring natural tunnels in Oregon.
Lava River Cave: As the longest uncollapsed lava tube in Oregon, Lava River Cave offers an impressive underground exploration journey. With a length of over 1.6 km, this cave allows visitors to walk along the spacious lava tube, admire unique geological structures, and learn about their formation process. You can explore this cave on your own, but you need to prepare flashlights or headlamps to ensure safety in the darkness.

Boyd Cave: Located near Lava River Cave, Boyd Cave is another lava tube, smaller but equally interesting to explore. This cave has more narrow and steep sections than Lava River Cave, offering a more adventurous experience for those who like challenges. Inside Boyd Cave, you will find unique lava stalactites and bizarre geological formations.

Lava Cast Forest: Although not a tunnel, Lava Cast Forest is also an interesting destination in Newberry National Volcanic Monument, related to volcanic activity. This area showcases natural molds of trees created when hot lava engulfed the forest, then cooled and left behind stone “copies” of tree trunks.
2. Bend Area and Deschutes National Forest
The city of Bend, located near Newberry National Volcanic Monument, is a popular tourist center in Oregon and a great starting point for exploring natural tunnels in the Deschutes National Forest area.
Pilot Butte State Scenic Viewpoint: While famous for its panoramic views of Bend and the Cascade Mountains, Pilot Butte is also a dormant volcano and may contain smaller lava tubes. Although not a primary destination for tunnel exploration, Pilot Butte is still worth visiting when you are in Bend.

Unexplored Lava Tubes: In addition to the famous caves developed for tourism, the Bend area and Deschutes National Forest also have many other lava tubes that are unexplored or little known. For experienced adventurers, finding and exploring these caves can be a challenging and exciting experience. However, it should be noted that exploring pristine caves requires careful preparation and expert knowledge of cave safety.
Tips for Safe and Fulfilling Natural Tunnel Exploration
To have a safe and memorable natural tunnel exploration trip, you need to note the following:
1. Prepare Equipment:
- Light Source: Flashlights or headlamps are indispensable items when exploring caves. Make sure the light is strong enough and has spare batteries.
- Hiking Boots or Trail Shoes: The terrain inside caves is often rugged, slippery, and has many sharp rocks. Sturdy shoes will protect your feet.
- Appropriate Clothing: The temperature inside caves is usually cooler than outside, even in summer. Wear long sleeves, a light jacket, and long pants to keep warm and avoid scratches.
- Helmet (Optional): If you are exploring caves with low ceilings or many falling rocks, a helmet will help protect your head.
- Water and Snacks: Bring enough water and snacks to replenish energy during the exploration.
2. Safety First:
- Go in Groups: Do not explore caves alone. Go with a group of friends or family to ensure safety and support each other when needed.
- Inform Someone: Before entering a cave, inform relatives or friends about your plan and expected return time.
- Pay Attention to Weather: Avoid exploring caves during heavy rain or when there is a risk of flooding.
- Follow Regulations: In managed areas, follow the regulations and instructions of park rangers or management.
- No Littering and Protect the Environment: Keep the cave clean and do not litter. Respect the natural environment and do not affect the cave ecosystem.
3. Enjoy the Experience:
- Explore Slowly: Don’t rush when exploring caves. Take time to observe and admire the unique beauty of the underground world.
- Learn About Geology: Read information about the formation process and geological characteristics of the caves you explore to better understand these natural wonders.
- Take Souvenir Photos: Don’t forget to capture memorable moments during your cave exploration journey with a camera or phone.
