Well Tami and I just returned from Put-in-Bay on South Bass Island Ohio. Great place to visit!
We left our rig back in Richmond Indiana and drove (3 hours) to Port Clinton / Catawba Point and Millers Ferry. We left our 1 ton dually at Miller's Ferry parking lot on the mainland at Catawba Island Point, it's free. There are other parking lots for $10 a day at the ferry if free parking is full.
You can take your car or truck over to the island on the ferry but there isn't a lot of room to park vehicles at the attractions, especially big vehicles.
There several campgrounds on the mainland near Port Clinton or Catawba Point you could stay with your RV, then take the ferry over for the day. The ferry is $9 / person one way and takes about 18-20 minutes.
Or if you have a small RV you can take it over on the ferry and stay at South Bass Island State Park.
We stayed at Ashley's Island House B&B on the island, a great place with 13 rooms with private bathrooms. We also rented a golf cart from Ashley's House $50 a day to get around the island. We took a cab $6 from the ferry landing to Ashley's House. Outstanding B&B, Dave the owner was great and accommodating and the hot breakfast was excellent.
There are several places to rent golf carts on the island but check the prices to get the best deal. The island is about 2 to 3 miles long so getting around on a golf cart is much better and several places to park the cart at all the attractions.
We visited Sept 16-17 Mon-Tues and it was real quiet and not a lot of tourist. On the weekends and at the height of the tourist season, it can get real busy and crowded.
We think it was a lot of fun and well worth the visit. We took in Perry's Victory & International Peace Memorial of the War of 1812 on Lake Erie. Perry was the Naval Officer that had "Don't Give Up The Ship" on his battle flag, and coined the Naval historical phrase "We Have Met The Enemy, And They Are Ours".
Other places we visited were the Heineman Winery, Maritime History Museum, South Bass Island State Park, The Butterfly House, South Bass Island Lighthouse, The Boardwalk. I upload to our YouTube channel a 30 minute video of our visit, as always our channel is non-profit. Link in our signature.
There are several other attractions including Crystal Cave where you can see the largest Geode in the world. The sunsets were equally wonderful at the state park. It was a lot of fun. Pick up a free map of the island that lists all the attractions at Miller's Ferry and they have tons of information.
If you want to get to the island in a hurry there is a jet ferry express over to the island at Port Clinton.
Did you know the US Navy had an aircraft carrier on the great lakes? See pictures and info about it at the Maritime Museum.
