Winter Weather Driving Advisory
If you are traveling to Oregon Caves during October through April, be aware of the snow hazards predicted. Visit NOAA for more information, and call or e-mail Oregon Caves regarding snow conditions. If you do drive up to the Monument, it is recommended that you carry chains or have traction tires. Be aware that tours are seasonal and are not offered from late fall to mid-spring. However, Oregon Caves National Monument is always open to visitors. Occasionally in winter, snow can temporarily close park roads until they are plowed.
