In the early summer, there are plenty of these beautiful lavender lupins on the side of the road. In fact, I've never seen so many of them as on Madeline Island. They are especially abundant on the Big Bay Road, which links La Point with the small Indian reservation at the other end of the island.
The Big Bay Town Park encompasses a lagoon and small stream. I noticed some people bringing canoes or kayaks to take advantage of the easy-flowing waters.
On Madeline Island, there's a "Big Bay State Park" and a "Big Bay Town Park." The State Park has more facilities, allows overnight camping, but charges an entrance fee, even for day-users. The Town Park has few facilities but is free. Both parks have sand beaches. I went to the town park and enjoyed myself. Fortunately, considering that it was early June, there were no bugs! If you visit later in the summer, you may not be so lucky.
You can rent a moped and really see the island! We saw a deer while tooling around. Its the perfect island to do this - its not too big, not too small. Traffic isn't too heavy or too fast. Really fun to do!
On Madeline Island, you can spend a few bucks and rent a couple of mopeds! Great way to see the island. WARNING: get off the ferry quickly and run to the moped rental shop... they run out of mopeds fast.
