Boyne Mountain Resort is a ski resort with a collection of accommodations in Northern Michigan located near Boyne City. The center piece is an upscale resort called The Mountain Grand Lodge and Spa. The Boyne Mountain Resort was originally co-developed by Everett Kircher, Jim Christianson and John Norton and is now owned and operated by Boyne Resorts. It is also the location of Avalanche Bay, the largest indoor water park in Michigan. Boyne Mountain has continued use of the first chairlift built, originally constructed in Idaho in 1936 for use at a resort in Sun Valley, Idaho. The lift was later moved to Boyne Mountain where parts are still in use today.
