One should walk the park to get the idea before entry. After walking out of the pavilion go left toward the bridge, but go past, down the hill until the fence ends, you will see a nice gentle rock entry point, the idea is to swim out to the island from there, drop down and catch the current across the front of the island, after the island there are 2 options: Drift to the Islander or swim across the canal behind the island to the east side of the fishing dock and exit thru the rocks, look close you see what I mean at the very end of the dock is a set of rock "stairs" to get out. Lots of fun!!!
81N to 13E to Alexandria Bay light, go left into the heart of A-bay, go straight until road T's, go left and then right into the park parking lot. Carry gear thru the pavilion and use tables on other side.
