The Mountain Top Arboretum is a living museum of trees and shrubs created for the education and pleasure of the public. Its founders, the Ahrens family, designed and planted a seven acre mountain top area starting in 1977, to display the range of native and exotic trees and shrubs that successfully adapt to the rigorous climate at 2,400 feet elevation. There are twenty three acres of displays in three distinct areas: the West Meadow, the Woodland Walk, and the East Meadow, and a 163 acre wild forest and wetland area called Black Spruce Glen which has trails along a fen, bogs, old growth hemlocks and mixed hardwood forest. The Arboretum is home to a wide range of mammals and amphibians. Over 70 species of birds can be seen and heard throughout the various habitats found throughout the Arboretum.
