treehouse in Downeast Acadia Region of Maine

Set in the middle of a field with views of the Union River, The Poplar is a quiet treehouse designed for stillness and comfort. It sleeps four, with a queen bed on the main level and a second queen bed in a loft above. Floor-to-ceiling windows frame the trees and the rapids, with a hot tub, smokeless fire pit, and 1.5 miles of forest trails just outside. Calm and secluded, yet close to downtown Ellsworth, Acadia National Park, and the beauty of Downeast Maine.

The Poplar Treehouse is equipped for comfort, quiet, and time spent well—whether preparing a meal, soaking under the stars, or watching light shift through the trees. Inside, you’ll find a compact kitchen with an induction cooktop, mini-oven, dishwasher, and essentials for daily cooking. There’s a combination washer-dryer, a small desk and chair, high speed fiber internet, and a wood-burning stove for warmth and atmosphere. A mini-split heat pump keeps the air comfortable in any season. Beds are made up with organic cotton and Oeko-Tex certified linens and towels, and the bathroom and kitchen are stocked with simple, plant-based cleansers.

Outdoors, the Poplar offers a private hot tub, a smokeless fire pit, a hammock, a propane grill, and outdoor seating. Private parking includes an EV charging station. The loft sleeping area is accessed by a sturdy ship ladder, handcrafted on site. Please use care when climbing. The loft may not be suitable for small children or guests with mobility concerns.

Please note: 1. Current rates reflect a significant discount as Arbor Camp continues to grow. While The Poplar Treehouse is complete and fully private, you may hear or see construction activity elsewhere on our 30-acre property as we build additional dwellings. It’s an exciting time—the forest is shifting, new paths are forming, and you’re part of the beginning.

2. While we love pets very much, we regret that we are unable to accommodate them at Arbor Camp. All indoor and outdoor features of the Poplar are yours alone to enjoy throughout your stay—from the fire pit and hammock to the grill and private hot tub. A code for the smart lock will be sent to you the day of check-in.
