Saginaw Bay is a large inlet in central Michigan that is filled with the waters of Lake Huron. Known as an excellent place to fish, especially in and around the towns of Oscoda and Au Gres, the Saginaw Bay area is also home to three municipal centers—Midland, Saginaw and Bay City—each offering a plethora of attractions. Saginaw boasts a large student population, as it is home to Saginaw Valley State University. Birders enjoy the nearby Shiawassee National Wildlife Refuge, a park that is a haven for more than 270 species of birds. The Bavarian village of Frankenmuth is the most popular tourist destination in Michigan, drawing millions of visitors each year. One popular Frankenmuth event is Zehnder's Snowfest, which occurs in January and is considered one of the top snow sculpting events in North America.
