Maple sugaring is Michigan’s oldest agricultural activity—dating back the early Native Americans. Supporting the state’s thriving agricultural industry, the Michigan Maple Syrup Association was formed in 1962 and is dedicated to the preservation of maple sugaring and the promotion of Pure Michigan maple products.

From mid-March through April, dozens of events are held throughout the state aimed to educate the public on the craft of tapping trees and boiling it down into maple syrup. For three consecutive weekends, the 5th Annual Michigan Maple Syrup Weekend, provides unique opportunities for the public to explore the sugar bush and the sugar shack. Following the natural warming progression, events are first held in the Southern Lower Peninsula (south of US10), March 18-19, followed by events in the Northern Lower Peninsula (north of US10), March 25-26 and throughout the Upper Peninsula, April 1-2.
