Mountain Top Arboretum is a public garden in the Catskill Mountains dedicated to displaying and managing native plant communities of the northeastern US, in addition to curating its collection of cold-hardy native and exotic trees. Its mountain top elevation of 2,400 feet at the top of the New York City Watershed creates a unique environment for education, research and pure enjoyment of the spectacular and historic Catskills landscape. The Arboretum trails and boardwalks connect 178 acres of plant collections, natural meadows, wetlands, forest and Devonian bedrock—a natural sanctuary for visitors interested in horticulture, birding, geology, local craftsmanship, hiking and snowshoeing!


"I go to nature to be soothed and healed, and to have my senses put in order."  
- John Burroughs
