Nestled in the stunning landscapes of Central Oregon, Skylight Cave presents an exciting escape for adventurers, nature lovers, and history enthusiasts alike. This natural wonder is not just a cave; it is a gateway into the geological past and a playground for exploration. Whether you’re an experienced spelunker or simply looking for a unique day trip, Skylight Cave promises an unforgettable experience.
The Geological Marvel of Skylight Cave
Skylight Cave is a lava tube cave formed by volcanic activity thousands of years ago. As molten lava flowed from the earth, it created a hollow tube that cooled and solidified, producing an incredible underground world. This cave is part of the larger Newberry National Volcanic Monument, which showcases the region's volcanic history and hosts diverse ecosystems.
The cave's name arises from the natural skylights in its ceiling. These openings allow sunlight to filter through, illuminating the cave’s interior. The play of light and shadow enhances its stunning visuals, making it a haven for photographers. A visit here not only reveals geological wonders but also offers education about the volcanic processes that shaped this unique environment.
How to Get There
Situated just outside the charming town of Sisters, Oregon, Skylight Cave is easily accessible by car, making it a perfect destination for a quick getaway. From U.S. Highway 20, take the turn onto McKenzie Highway, following the clear signs to the cave. The drive winds through picturesque forests and offers stunning mountain views, building anticipation for the adventure ahead.
Upon arrival, visitors will find a small parking area. It is wise to arrive early, especially during the peak summer months, to secure a good spot. The short hike to the cave entrance is well-marked, ensuring visitors can easily navigate through the scenic terrain.
NOTE on caving. It's cold in caves, with temperatures in the 40s Fahrenheit. Just because it's 90 degrees Fahrenheit outside doesn't mean you shouldn't be prepared. If possible, wear a headlight, as this will free up both hands, which you will need for balance and feel. YOUR CELL PHONE flashlight WILL NOT give off enough light. Wear a helmet on your head. Gloves are also a good thing.

The Google Map is of the actual cave (not the parking area) and is correct, but once you’re walking towards the cave, you’ll need to use your eyes. Eventually, you’ll spot the sign on the right telling you a bit about the cave. The entrance to Skylight Cave is just behind the sign.

The entrance to Skylight Cace is down this ladder.

What to Expect Inside
Once inside Skylight Cave, be prepared for jaw-dropping formations that adorn the walls. The cave stretches along an extensive network of tunnels and chambers, with heights reaching up to 30 feet. The first thing you’ll notice is the varied shades of rock shining in the cave’s gentle light.
Explorers can meander through different sections of the cave, each revealing its unique beauty. The iconic skylight presents stunning views of the outdoors.
Skylight Cave is a lava tube, a hollow tube that was formed by lava flowing through a cooled fissure on the outside. The lava flowed out, leaving the outer shell.
Skylight Cave is the result of that outer shell collapsing inwards, creating a sky-lit cavern to explore.

There was only one couple here when I got here, and he was teaching her how to rappel from the top down into the cave.

Those beams aren’t a permanent display, so you’ll need to time your visit to Skylight Cave to get the stunning effect.
I went in June at around 10:00 am and left around 11 am. I was photographing and having too much fun, plus waiting for the right conditions. I was worried I would miss my window because the light wasn’t the greatest at first, but it improved around 10:30 am, and I was able to capture the beams.

If you go right, you can explore the cave for around 900 feet until it dead ends.

If you go left, you’ll walk about 300 feet towards a small light. As you get closer, you’ll look up and see three holes in the top of the cave.
If you’re here at the right time of day (more info on this below!), you’ll be rewarded with an extraordinary display of sunshine blasting through the “skylights” of the cave ceiling!
Photography Opportunities
For photography enthusiasts, Skylight Cave provides countless stunning visuals. The interplay of light and shadow, combined with the vibrant colors of the walls, creates a captivating backdrop for exceptional photos.
Whether you shoot wide-angle landscapes of the cave or focus on intricate details of its formations, the cave invites creativity. Remember to bring a tripod for low-light conditions and explore various angles to capture its beauty best.

Skylight Cave was my first stop and also my favorite. The most challenging part of getting to Skylight Cave is the drive. It's about a 6-mile drive down a dirt road, and I would recommend a four-wheel drive vehicle due to the numerous deep potholes and large rocks. The cave is closed from September 15 through April 30 due to the presence of hibernating bats. The cave is entered via a steel ladder through a collapsed roof section. The most notable features of the cave are its three skylights in the eastern passage, for which the cave is named.
Safety Tips for Exploring Skylight Cave
Exploring caves is exciting, but it does come with risks. Here are essential safety tips to keep in mind during your visit to Skylight Cave:
Stay on Designated Paths: Wandering off established trails may lead to unsafe areas. Stick to marked routes to ensure safety.
Bring a Flashlight: Although the skylights provide some illumination, certain areas remain quite dark. A good flashlight will help you navigate more effectively. NOTE: I prefer a headlamp so you have both of your hands free to help navigate.
Watch Your Step: The cave floor can be uneven and slippery, making it crucial to remain attentive to your footing.
Travel in Groups: Safety in numbers is wise. Exploring with others ensures assistance is available if needed.
Check Conditions Before You Go: Seasonal weather can alter cave conditions, so verify that the cave is open and safe to visit before you go.
Wildlife and Flora within Skylight Cave
Another captivating aspect of Skylight Cave is the rich ecosystem thriving within its calm, dark surroundings. Visitors might spot various bat species hanging from the ceilings or flitting about, as well as unique cave-dwelling insects adapted to life in darkness. The cave is home to over five species of bats, including the Townsend's big-eared bat.
The skylights host small plants and mosses that have uniquely adapted to this environment. This combination of life, where sunlight meets the underground, creates a unique atmosphere that appeals to both nature enthusiasts and photographers.
