If you live in CRE, there are 3 bay front beaches and at least one lake. In CRE, your SUPPOSED to have a beach pass to use those beaches, and you have to be a resident to get one of those, but I have never heard of anybody getting kicked off for not having a sticker on their windshield.
CRE 5-oh is too busy chasing down the more serious criminals...those with dogs that like to swim on these hot days.
Under the solomons bridge their is a public boat launch and fishing pier, but no beach.
Point Lookout has some pretty nice beaches, although it is a little drive to get down their....'bout 45 minutes from Lusby.
Not sure if Drum point has any beaches that are a little more public or not.
But the base beach has a pretty nice beach too, if you have base access.
