Halloween comes earlier on Mackinac Island – the weekend of October 27-29! This weekend typically marks the last big weekend before most island businesses close for the season. Celebrate Halloween with the Great Turtle Trail Run, trick-or-treating for kids through downtown shops, and Halloween costume parties for adults throughout island establishments in the evening.
