Lake Superior provides opportunities for sailing, power boating, fishing, swimming, smelting, ice racing and more. It is the home of the Apostle Islands National Lakeshore, which consists of 21 of the 22 Apostle Islands.
The bay is a large, sheltered area that runs along the northern coastal edge of Ashland County. Chequamegon Bay is considered a world-class fishery. In addition, it provides a large area for recreational boating and beautiful scenery. You will find parks, shelters, a marina and swimming beaches along its shores.
The rich maritime history of the Great Lakes is reflected in the Apostle Islands Lighthouse Celebration, an annual event held in September.

The Breakwater Lighthouse is located at the end of the Ashland breakwall.
