Mom and lots of ducklings on the Debsconeag Deadwater, Maine.
Two natural sandy beaches on the Deadwater (Omaha and little Omaha) have state of Maine-run campsites. A good deal for less than $4 a night! Great kayaking around the Deadwater (with views of the whole range of mountains in Baxter State Park from Doubletop to Katahdin). You can also paddle to First Debsconeag Lake, where there are campsites at both ends and access to the trail to an Ice Cave!
