Yes, here in Southern Oregon, we have the amazing Out ‘n About Treesort, filled with tree houses to stay overnight in. We had a wonderful experience there with kids, but of course it’s just as magical for adults. You’ll want to check the official website for up-to-date information on pricing.
The treesort is located outside of Cave Junction, Oregon, off Highway 199 (Redwood Highway). I would definitely suggest pairing a stay there with a visit to the nearby Oregon Caves National Monument or to the redwood groves on the Oregon Coast. Our favorite place is at Alfred Loab State Park on the Chetco River.
