[1] Blue Jay Creek begins at a spring, about 3.4 kilometres (2.1 mi) east of the community of Sandfield on Lake Manitou in Central Manitoulin township, and at an elevation of 275 metres (902 ft).

The creek heads southwest, takes in the right tributary Black Creek and reaches its mouth at Michael's Bay on Lake Huron, near the community of Michael's Bay, and about 1.2 kilometres (0.7 mi) southeast of the mouth of the Manitou River and 7 kilometres (4 mi) northwest of the community of South Baymouth.

The Blue Jay Creek and Manitou River Enhancement Strategy[2] was completed in June 2001 and approved in December 2003 by the Manitoulin Streams Improvement Association.

[5] Blue Jay Creek Provincial Park is notable for its raised beach and swale landforms, which are some of the largest on the island, with upland willow thickets.

[5] The park was created in 1997 as part of the Ministry of Natural Resources' "Keep it Wild" campaign, out of previously private land that was donated to the government in 1989.
