About

Water carved Oregon Caves through solid marble, at the end of a 20-mile road from Cave Junction. Most caves like it form in limestone or gypsum. The only way in is a ranger-led tour, run from May to the start of November. The 90-minute Discovery Cave tour climbs more than 520 steps at a steady 44 degrees, and on one 88-foot passage the ceiling drops to 45 inches. Children shorter than 42 inches can't go, even carried. Buy same-day tickets at the Illinois Valley Visitor Center in Cave Junction before you head up; the last 8 miles of the road are steep, with blind corners and deer. On summer Fridays through Sundays, the day's last tour goes by candle lantern, ten people at most.
