Oregon Caves National Monument
Weather

The elevation at the monument is 4,000 feet (1,220 meters) and as a result, we experience comfortable summer temperatures (65-85 F, 18-29 C) and snowy winters. The climate of the region is strongly influenced by the ocean which contributes to over 50 inches of rain per year. Expect rainy weather during spring and fall at the Monument and bring your rain gear! 

If you plan on attending a cave tour, you should bring a warm sweater and sturdy shoes to dress for the 44 F (7 C) cave.
From the vista on the Cliff Nature trail you can see the nation's largest serpentine rock outcrops in the distance.  

Did You Know?
The mountains surrounding Oregon Caves are composed of ocean crust including rocks uplifted directly from the mantle. These mantle rocks make up one of the largest serpentine rock outcrops in the nation.
