Hi, I have been looking at rental cottages and camps on the finger lakes. Most seem to say the swimming areas are shale(not sure of the spelling) I've also read the need for water shoes. Are there some areas like this or are all of the finger lakes the same? I would like to find a sandy beach suitable for swimming. We are traveling next summer for a wedding on Canandaigua Lake. All camp rentals I have found on this lake are out of our price range,so have been looking at other lakes. Any advice would be great.
