Big Bay State Park is on Madeline Island in Lake Superior and is one of the Apostle Islands. The only way to arrive is by ferry boat. It is pricey to bring your RV. Ours is only 26 feet but we had a bike rack and two bikes that brought our total length to 30 feet. If you are a tent camper and traveling in your car, it will be about $27 for your car and$16 for each passenger round trip. www.madferry.com   

The first thing about Big Bay State Park is your RV is on a ferry boat. The ferry is very organized but small and depending on the time of day and day of the week you may need to wait for more than one ferry to depart. Once you get to the park, it is quiet and filled with natural beauty. The campground has both electric and non-electric sites. We visited in mid-July and it was cool and breezy and we did not need our air conditioning. There is no dump station at the park. There is a dump station at the airport about 5 miles away where you can dump. 

This is the first WI State Park I have seen with hose hook up on the water stations. There is a drinking fountain, bottle filler and hose hook up on each water station and there are many of them through out the park. We were able to fill our RV from the hose hook up. There are 60 sites with 7 walk in sites. All sites are well spaced and have a newer picnic table and fire ring/grill. The park is very well kept with 8 trails in distance from.1 to 4 miles. The Boardwalk trail that follows the bay is flat and has many interpretive signs. It connects to the Big Bay Town Park. The beach was not crowded when we visited mid-week and views of Lake Superior where breath taking. When you arrive by ferry you are in the town of La Pointe. There are restaurants, shopping, a laundromat, bike, moped and canoe/kayak rentals. It is six miles from La Pointe to Big Bay State Park.
