If you look in the first pick that is Perrys Monument from the west side of Kellys Island.
Once you get to Port Clinton and stop at
Walmart to stock up head east on 163 to Marblehead and ride the Big Orange Boat

Mid to end of August they have a one ring circus that comes out to the island, elephant helps setup the bigtop. They have a free movie weekend where they inflate a 50' screen at the ball field by the school and show fairly recent movies, last year the new King Kong was on the list...love the Kettle Korn
If you want to go over to Put in Bay

There is also a state park campground on South Bass Island where Put in Bay is

it fills up quick tho.
Kelleys Island is a great place to just go and fall off the face of the earth for a while. If you have a golf cart you can ride it around the island. It's not real commercial, they have a few shops downtown, gotta get the Moose Tracks ice cream then go into homemade fudge shop to finish the chocolate high. For the "night life" crowd head over to Put in Bay and the block long bar.
If you want to stay on the mainland for a few days there is East Harbor State park campground in Lakeside, between Port Clinton and Marblehead.

and Cedar Point is about 15 miles from East Harbor in Sandusky.
