Cresap Bay is a campground on Lake Merwin on Pacificorp land near Amboy, WA.
Full of tall trees and ferns, with large-ish sites that are separated by trees and shrubs.
Very clean, nice attentive staff.
Swimming area with beach.
It caters primary to boaters and watercraft users with a nice boat ramp, but also has a free moorage dock.
There were very few insects when we were there at the end of June, and lots of birds to see and hear.
There is an area just for tents.
No hookups, and a 7-day limit, as the place is VERY popular.
