One of my favorite places on the east coast. A huge beach that's swimable just about anywhere stretching as far as you can see in both directions.
There are many different parking/picnic areas off the beach and for bikers, this beach runs right along the Confederation parkway in the provincial park which has almost 13 km of paved, nearly flat biking surface.
The scenery is great which ever way you turn and the food in the area is fantastic. Some of the best seafood around can be found in the restaurants that surround the area.
Just take route 15 from Charlottetown and you're there in 20 minutes!
