From Cave Junction, take Oregon Highway 46 (also known as Caves Highway) and follow the signs. The road is narrow and winding, so drive carefully, especially in winter or wet conditions. There is no public transportation to the caves, so renting a car is the best option if you’re flying into the area.

Weather at Oregon Caves National Monument

The weather at Oregon Caves varies greatly by season due to its mountainous location. Summers (June to September) are generally warm and dry, with daytime temperatures ranging from 70°F to 85°F (21°C to 29°C). This is the best time to visit the caves and surrounding trails.

Winters (December to February) can be cold and snowy, with temperatures often dropping below freezing. The road to the caves may be closed during heavy snow or icy conditions. Spring and fall are mild but can be rainy, so visitors should dress in layers and bring waterproof gear.

Inside the caves, the temperature remains a constant 44°F (7°C) year-round, so a jacket is recommended no matter when you visit.

Why is Oregon Caves National Monument Famous in Oregon?

Oregon Caves is famous for its rare marble cave system. Unlike many limestone caves, these caves are formed in marble, a metamorphic rock, which is relatively rare in the United States. The complex cave network features stunning formations like stalactites, stalagmites, and flowstone.

The monument is also known for its rich biological diversity and its historic chateau, which is a National Historic Landmark. The unique geology, combined with its remote and scenic setting, makes Oregon Caves one of Oregon’s most fascinating and lesser-known natural wonders.

Entry and Visit Details

Entrance to the monument grounds is free. However, guided cave tours require a ticket. As of the most recent information, adult tickets cost around $10–$15, with reduced prices for children and seniors. Tickets can be purchased online or at the visitor center, but availability may be limited during peak season, so advance booking is recommended.

The park has limited amenities, including a visitor center, restrooms, picnic areas, and the historic Oregon Caves Chateau (when open). There are also hiking trails around the monument, offering scenic views of the forest and mountains.
