Taking our 3 teen boys to west coast this summer. We're renting an RV for 7-10 days, staring in Portland and heading south. Want to see the Redwoods, beautiful coastal scenery, and looking for some fun, unique adventures for us and the boys. Having the RV, we plan on staying in campgrounds, with probably a night at the treehouse campground in OR. Would appreciate any suggestions and ideas to make it a great family trip!
