Mardela Springs is an authentic small town. There's a bunch of unique things to do there. You can see an original Mason & Dixon marker and bone up on the local history at one of their historic museums or you can check out the nation's largest indoor coral farm. No joke! This little town has a lot to offer. And when you're done with your exploration, head over to the Sharptown Fireman's Carnival that runs through the entire month of August. You and your kin can ride any one of their antique carnival rides, play games, or even enter the raffle. And when you work up an appetite you have to try one of their oyster sandwiches. They're world famous!
