Harris Beach is beautiful. There is Also Bullards Beach just before you get to Bandon. Bandon is a quaint little town with lots to see. The Ocean drive in Bandon is quite spectacular. But you best make reservations at any Oregon State Park because they fill up rather quickly. It might even be too late already. "Winchester Bay" has a lot of RV sights The city of Reedsport is kind of ugly but Winchester is just a mile or so down the road and is very pretty. You guys make sure to have a fun trip.
When you go through Coos Bay make sure to stop and take in Shore Acres. Spectacular views of the Ocean and a pretty little ride.
