About Avalanche... The Avalanche Mountain Preserve comprises 300 plus acres of woodland located on the southern border of Boyne City, Michigan in Charlevoix County and extends beyond the City limits into Wilson Township. The area is a predominantly sloping terrain with approximately 90% of the park wooded. The area offers many types of recreational activities including hiking, biking, skiing, skating, jogging and snowmobiling and the newest additions, an archery range and disc golf. Maintenance and planning for the future of the park are the responsibilities of the Boyne City Parks Department and the Boyne City Parks and Recreation Commission, respectively. Donations for the maintenance and future development of the park are accepted through the City Manager. If you are interested, please contact the City at (231)582-6597.
