Amazing Glamping Retreat on an Island: Charming Tree House in Monmouth, Maine

Tree house in Monmouth, ME

8 guests • 3 beds


This off-the-grid unique home is perched on a 14-acre island 1/2 mile from shore on Lake Annabessacook. The 900 sq. ft. octagonal home, built around a live Red Oak tree, is designed to make your stay comfortable amid the forest canopy.

Adventure! Canoe around the island, and enjoy the sights and sounds of Maine's natural beauty: fresh air, clean water, and the songs of the loons.
Serving the naturally curious since 2015.

######## SPACE ########
The Oaktagon Tree House on 1 Big Sustainable Island is an octagonal home that gets its name from the live Red Oak tree (her name is Annie) that grows through the middle of the home. It's a great place to enjoy a family vacation, host a gathering, or just unplug from the hustle and bustle. Step inside and you will be awestruck by the sweet pine panel aroma and the sounds of living in the canopy.

It has an open cathedral living/dining room with a fold-out futon, a small breakfast table and a large dining table that seats six. Electricity is limited to the solar lighting system, so bring a battery to recharge your phone.

RETURNING GUESTS: We appreciate folks who return year after year. Remind us of your last stay and we'll honor last year's nightly rates. If you are looking for an exception to our minimum night requirements, please reach out.

MINIMUM NIGHT STAY EXCEPTIONS: If you are looking for an exception to the minimum night stay requirements for last minute reservations, we do that. Please just send us a message and we'll do our best to fit you in for a super short stay.

COOKING OPTIONS: Cooking is easy, so pack light. A compact and complete kitchen has all the cooking utensils you will need to prepare meals -- just bring a cooler with your favorite food, a block of ice, and we'll provide the kitchen to get the food prep done. We supply: kitchen utensils, dishes, pots and pans, French press, coffee, tea, sugar, salt, pepper, and drinking water from our homestead well. You also can cook on the gas grill with a side burner that’s on the back deck, or over an open fire.

A small indoor 1/2 bath adds modern convenience to the experience. It is equipped with a composting toilet and hand sink. Take a hot shower (available May 1 - October 15) in a separate, shared building a few steps down the path.

Warm your hands and feet in front of the small woodstove - kindling, and firewood come with the accommodations. (You can't visit Maine without at least seeing a woodstove!). Use it for cooking, creating some ambiance, or just taking the chill off a cool evening breeze.

Sleep soundly in the queen size comfy bed in the sleeping loft that is made up with extra blankets and a comforter. The futon couch converts to a queen size bed in the living room. Another lounging option is to linger in the indoor hammock that you can attach to the tree in the living room. Island life is barely "roughing it", even though there is no grid-electricity and running water.


The large deck looks into the canopy. It is perfect for grilling and enjoying an outdoor meal, bird watching, and having a firefly counting contest. There is also an outdoor fire pit, complete with plenty of free firewood to enjoy a fire while enjoying an evening breeze.

The Oaktagon comes equipped with a few fishing poles and a small tackle box with an assortment of jigs, flies, and line. You are welcome to use them -- just be sure to get a fishing permit before you do so you can be on the right side of Maine's fishing laws. Annabessacook is known as a world class bass fishery -- we don't even have to stock 'em -- it's that good!

FREE STUFF: Every Maine Island adventure includes: camp chairs, unlimited firewood, lantern, fire starter, matches, canoe or kayaks with life vests and gear. Explore Annabessacook Lake! On the island there is a rope swing, a mile of walking paths, benches and hammocks.

VACATIONING WITH YOUR DOG? Send us a request! The Oaktagon is pet-friendly for most of our furry friends. The dog fee is $30 per night per dog. Request permission by sending us a picture and brief description of each dog's demeanor toward other pups and humans. During the day, dogs should be leashed as there might be others visiting the island.
######## ACCESS ########
Guests enjoy exclusive access to the Oaktagon Tree House where they can enjoy privacy and shared access to 1 Big Sustainable Island.

There's lots to do on 1 Big Sustainable Island and (as has been the tradition for generations in the neighborhood) visitors are encouraged to stop by (so expect some company from the neighborhood on the island during daylight -- after dark, however, the island is closed to the public). Activities in these shared areas include:

Hiking or walking on more than a mile of trails
Swinging off the rope swing at the lake's edge
Cooking over an open fire
Watching the sunset from Sunset Rock
Resting in one of the hammocks sprinkled about the island
Fishing off the dock

We are happy to provide safe luggage storage so you can enjoy free early arrival or free late departure. Guests can take advantage of the shared areas and activities either before check in or after check out.

######## NOTES ########
OUTHOUSAPHOBES: We're with you!
New guests might wonder about our island, off-the-grid bathrooms. Rest assured that our compost toilets are designed with usability in mind. They smell great!

We have all been to rural outhouses where this is not the case. It's the number 1 complaint (or is that #2?). Which is why, when we built each of our toilets facilities, we did something different. Through management of airflow, separation of liquids from solids, application of saw dust, and optimizing the force of gravity, we have a composting toilet system that has been in place for years with very little odor and maximum sanitation. So rest easy: if a member of your party is an "outhousaphobe", know that so are we!

So that guests looking for longer stays have options, our minimum night stay (MNS) requirements tend to start high and then fade away. So if you've got a quick stay in mind and are surprised by our MNS requirements, please check back with us. The closer we get to an empty night, the more flexible we will be.
