The Cliff Nature Trail in Oregon Caves National Monument is a scenic 1-mile loop starting behind the visitor center and ending near the cave entrance. The trail gains 370 feet in elevation and reaches a high point of 4,320 feet; it climbs to a viewpoint with stone benches, offering panoramic views of the Illinois Valley, then descends back through the forest. It's family-friendly, features wildlife, and intersects with the Big Tree Trail if you want to add more mileage to your hike.
