Events: Weddings, Families, Retreats

My second stay at BSI last weekend was as impressive as my first two years ago. The island setting, the creative accommodations, and the owner's sterling customer service all support my highest possible rating. Paul in Westbrook.

Incredible trip - it sounded too good to be true at first but 1BSI delivered 100%. Imagine packing for a nature getaway and being handed a whole list of things you don't need to bring! If you're reading this far in - don't hesitate to book as you won't regret it! Kent & Heather do everything they can to make it a wonderful retreat. As another reviewer mentioned, they are there if you ever need them but also give you your space to enjoy the wilderness. You can tell this is a lifelong passion project for Kent - there are upgrades being worked on throughout and I'm looking forward to my next visit If you're into sustainable living/traveling (and even if you aren't)- it's refreshing to see a project that stays true to their core mission & values. The realization hit me one night as I was building a cozy fire with some newspaper they provided as kindling. As the young fire grew, I noticed the newspaper had a crossword puzzle that had already been filled out. I realized that sustainability at 1BSI isn't a marketing ploy but an authentic way of life. The beauty of nature rests in it's authenticity, making this island a perfect getaway to reconnect

We LOVED our stay on one big sustainable island. We stayed specifically on the smaller island, Naughty Dog Island, and loved the privacy and connection to nature. Highly recommend staying here!

Just came back from our second trip to naughty dog island and can’t wait to go back next year!

Loved our stay here!! So relaxing, waterfront setting and very nice people on the island!

If you are looking for the most peaceful place to clear your head look no further.. One Big Sustainable Island is the most beautiful place to stay. This was my second trip and I couldn't be more happy. Kent is so helpful and has wonderful recommendations. I used the kayak, canoes and the stand-up paddle board! I even caught a fish! Thank you Kent and Heather!

We had a great stay at Naughty dog island. It was the perfect place to relax. We did lots of fishing, sleeping on the hammock and cooked yummy meals. Kent was the best host! Already planning our trip for next year!

We love Obsi! This was our second trip to obsi and our second time staying at Loon Point, it is without a doubt our favorite spot to connect as a family. (Me, my 8yr old son, our dog) A 100% zero stress camping trip-thank you Kent! Everything we needed was provided, minus the food, drinks, (other than water which is delicious and provided by Kent, and less to pack yay!)and clothes. Can't wait to go back and make some more memories....relax, connect, fish, grill, canoe, swim, relax, walk, breathe, listen to loons, read, sleep in a hammock, paint, cook a s'more, watch the sunset, photograph a shroom, sit by the fire and star gaze, disconnect and decompress... repeat! Thanks again for bringing Wes the worms and bobbers as he requested Kent, they really made him fall in love with fishing! We look forward to planning next years family trip to this beautiful escape.

My husband and I recently stayed in the Octagon House on the island. It was the most beautiful place to relax have fun and get back to nature. Kent our guide was so incredibly kind! He takes you on a boat over to the island and shows you everything. We used the free kayaks and unlimited fire wood. Watched the most gorgeous sun set! It's truly the best experience! Thank you Kent! We will be back next month!

Went here for a 2 night stay last weekend. Had car touble on the way up and a family emergency, and Kent and Heather were beyond accommodating. As for the island itself, we could not believe how private it was. All 5 sites were full Saturday night and we had no idea. We felt like (and thought lol) that we were by ourselves on the island. We did see Kent and Heather on Saturday and chatted a bit but they went out of their ways to be always available but give us so much space to enjoy ourselves. The site itself was absolutely lovely. We stayed in Hemlock Haven and next time would like to try out Loon Point. All of the basics you need are provided, along with special touches like books and games. What a perfect place to escape from life for a weekend, leave your phone and watch in the tent, and explore. We cannot thank Kent and Heather, Sky, Bella (and the younger brother who's name is escaping me at the moment) enough. This was our first vacation together and despite our challenges we had the most amazing time just being surrounded by an almost untouched peacefulness. We cannot wait to come back at least once a year, and plan on bringing family with us as well. See you again soon!
