Oregon Caves winds through marble deep in the Siskiyou Mountains, a 'marble hall' cave formed by acidic water dissolving ancient metamorphosed limestone, discovered by Elijah Davidson in 1874 when his dog chased a bear inside.
Take the guided cave tour past flowstone and moonmilk formations; young kids can earn a Junior Ranger badge. For a challenge, book the off-trail caving tour, crawling and squeezing through the cave's wild sections.
