About 2 miles max
We skied once around the loop to the right (the east side trails), including the cross-trails, and it was just under 2 miles. The online maps look like the west side trails are a little longer. http://wildadirondacks.org/heaven-hill-trails-map-directions.html
Good question. The name is for development. They had walkways but in not sure it was greater than that.
