In southwest Oregon, this relatively small park is easy to miss, along a winding road in the mountains and a long way from anywhere — but it’s worth seeking out. Sometimes referred to as the “marble halls of Oregon,” the park’s dramatic marble caves feature a flowing river, ancient wildlife bones, petrified rock gardens and caverns to explore.
The park also features a variety of plants and animals that live only in the region and a charming, rustic lodge with a double fireplace and a stream running through its dining room. Visitors can take a standard cave tour or strap on a helmet and get muddy on the Off-Trail Cave Tour where rangers explain caving techniques, etiquette and conservation.
