Eco-Island Resort:14 Private Acres, 5 Unique Stays

Summary:
Island Adventure - Weddings, Reunions, Events
1BSI is now taking 2026 bookings on its 14 acre natural island playground. Experience island life in a treehouse, Aframe, glam tent, dome, floating cabin, and two dining tents to seat 50. REMOTE & RUSTIC DOES NOT MEAN ROUGHING IT. Bring clothes, friends, off-leash pups & coolers of food. We’ve got the rest: easy transport, comfy-real-beds, cooking options, hot showers & super clean, Maine Guide hospitality. For all levels of nature lovers.

The Space:
Preparing for an island event is a breeze. We supply everything you need for a unique Maine island experience including help with getting your crew organized and pumped.

When you schedule your event for all of 1 Big Sustainable Island, you experience all five of the unique living spaces (tree house, Aframe, glam tent, dome, and floating cabin), the two dining tents for event and meal gatherings, as well as the privacy of the entire island for your guests (staff available and on-call to address any needs).

Sleep soundly in our 5 comfy queen size beds all made up. Our 5 futon couches convert to full-size beds. Lounge in any one of our 10 island hammocks. Amenities include: 4 compost toilets and a hot shower (available as long as temps at night are above freezing) with towels and soap nearby, a cold plunge sauna, dozens of canoes, kayaks, and SUPs, miles of scenic walking trails. Island life is barely "roughing it", even though the electricity is battery limited and plumbing is eco-unconventional.

HOW DO I GET TO THE ISLAND?
Every island adventure begins at our shoreside parking/dock area. From there, your crew has options: Paddle, Ferry, or BYOBoat. Know that we make island access for you, your crew, and your gear convenient, safe, free, and part of your adventure.

RETURNING GUESTS: We appreciate folks who return year after year. If you've misplaced the Island Withdrawal Syndrome coupon code, remind us of your last stay and we'll send you a new one. We can't have you suffering from IWS, now can we! Also, if you are looking for an exception to our minimum night requirements, please reach out.

COOKING OPTIONS: Cooking is easy, so pack heavy on food, and light on gear. We supply every tool you'll need to feed a hungry group after a day of island life: kitchen utensils, dishes, pots and pans, French press, coffee, tea, sugar, salt, pepper, drinking water from our homestead well. Cooking can be done at each stay or at our event tents for dining together.

FREE STUFF: Every Maine Island adventure includes: FREE island transportation, camp chairs, unlimited firewood, lanterns, fire starters, lighters, canoes, kayaks, or stand-up paddle boards with life vests and gear.

PUPS ON VACAY: We're dog people. Send us a request! 1 Big Sustainable Island is pet-friendly for most 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. The good news is that when you rent the entire 1 Big Sustainable Island, dogs can be off leash without any worries!

Getting Around:
GETTING TO THE ISLAND:

CHECK IN & CHECK OUT WITH FERRY SERVICE:
For Private Island Events we offer three round trip ferry services daily, during daylight hours, at times that work for your crew. We can transport up to 25 people with gear at a time on our two pontoon boats and floating side cars.

BYOBOAT
Bring your own boat or boat plane - we have a public boat launch, free overnight parking for your trailer at our place, and free island dock space for convenient boat tie-up.

PADDLE THE LAKE
Take one of our canoes or kayaks and paddle the 30 minute trip across the lake to a stay (weather permitting and during daylight only). We can shuttle gear on the next ferry trip, if you want.

FREE PARKING: Park 20 vehicles in our private and secure parking area for free

Other Things to Note:
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 building our toilets facilities, we did something different. Through management of airflow, separation of liquids and solids, application of saw dust, and optimizing the force of gravity, we created a 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!

I HAVE A SMALLER GROUP:
If 14 acres and 5 stays is too much for your needs, check out our smaller private island adventure at Naughty Dog Island, suitable for a group size of 1 to 8. It's private, remote, leash-free, on the same lake, and just as convenient - only for smaller groups:

THIS IS GLAMPING, NOT CAMPING, WE DO THE WORK, SO YOU CAN PACK LIGHT!

REMOTE WORK - Wifi, cell, and battery recharges
Cell reception registers 3 bars and 5G on the island . So, with any smartphone or laptop, remote work gets done. Bring your cord and we'll take phone and laptop battery charging from there. If you need our data plan, we offer a mobile hotspot upon request. There is a catch, however. If you need us to keep how easy it is to get online a secret, we can do that, too. Telling the office or the teens how easy it is to get on line on your island adventure will be up to you!
