The best time to visit Muskegon is in May, June, September, and October, which avoids both the hot summers and the cold winters. But winter can also be a good time to visit. For example, Muskegon State Park is great for water adventures in the summer. But in the winter, you can enjoy the Luge Adventure Sports park—which has one of only four luge ice tracks in the country and options for adaptive sports year-round.
