Suspended eight feet above ground, treatment rooms are connected by a walkway woven through trees and are outfitted with birch cabinets, mirrors framed in tree bark, and tree branches placed together to form circular tables. Guests can relax on tables adorned with plush bedding while listening to the sounds of the leaves rustling outside.

Tree Spa's products are designed to be as nourishing to the outside of the body as their ingredients are to the inside. Free from chemicals and preservatives, the Farmaesthetic products are made with organically grown herbs, flowers, oils, and grains. Milk, honey, lavender, oatmeal, and cornmeal are all ingredients that are incorporated into skin care treatments, as well as rosemary, mint, and lavender from Hidden Pond's farm.

A sampling of spa experiences include Maine Honey Body Buzz with Warm Remedy Wrap, Tree Spa's signature body treatment; Pure Fusion Bamboo Therapy Massage, an invigorating massage inspired by ancient Chinese, Indonesian, and Japanese rituals; and Pure Earth Heated Stone Therapy.
