Tree Climbing at Silver Falls is the only tour operator in the United States with government permitted access to guide participants up some of the largest and rarest trees in the world, 200-300 ft/60-90 meters tall old-growth trees, in Oregon State Parks. Our unique climbing activity lets you explore beautiful ancient forests, in a fun and educational ecotour type experience. Don’t settle for normal, an adventure of a lifetime, that less than .001% of the population has done, waits for you.
