We had such a fantastic stay! This was our 2nd stay on 1BSI and certainly won’t be our last! We had a lovely paddle out and Kent had our things waiting for us on our private dock when we arrived. The houseboat was perfect with so many thoughtful touches. The fairy lights and tea lights lit up the dome so beautifully at night made for a truly unforgettable experience with the water rocking us to sleep. To anyone on the fence about booking this stay, DO IT!

Our stay on the Star Gazer floating island was an unforgettable off-grid adventure! We booked this getaway for my son's 11th birthday, and he loved every moment—especially the campfire and s'mores. Having our own private floating sanctuary on the lake offered the perfect balance of excitement and relaxation.<br/>We spent our days kayaking, pedal boating, fishing, and exploring hiking trails. The sunsets across the open water were pure magic. Even on a cloudier night, resting inside the dome watching the open sky while feeling the gentle rhythm of the lake waves was an out-of-this-world experience.<br/>The dome was comfortable, clean, and well-maintained. The staff was incredibly kind, communication with host Kent was seamless. Host was a very professional, helpful and kind to everyone. Special thanks to Captain Ken for the boat rides and helping shuttle all our luggage to and from the island. We couldn't have asked for a better stay and can't wait to return! It’s a best find for us ❤️

This stay was amazing!!! Peaceful and calm!! Really brought us back to nature!! No one can tell you how truly beautiful the the stars are at night till you are laying under them to fall asleep cozy in bed with no light pollution!!! This place was truly amazing. We will be back!!! We want to stay at all of the sites now. Kent was amazing. They let us borrow a cooler and literally brought a pen to us (by ferry) so we could write in the guest book. 1 Big sustainable island is the best!!!!

Our stay was wonderful. We had the chance to get away from the hustle and bustle of life and catch our breath for a few days. I highly recommend staying on 1BSI, it was the perfect balance of feeling isolated while not feeling like you were properly in the middle of nowhere making fire with sticks. The perfect place to listen to the water, watch the birds, and sit by the fire.

I was looking for a nice little getaway from the everyday grind and boy did I find it with Kent's rental. The lake is absolutely beautiful. The island is so peaceful. Kent was always kind and available for any questions or anything you needed. I would 100% go back to this little slice of heaven.

The beginning of your adventure starts off with a beautiful boat ride to the island. Kent has extensive knowledge of the area, including the historical aspects regarding the vast native American population and their use of the island. If you love bird watching, this adventure is for you. You will see and hear Loons throughout the day. We also has a bald eagle swoop down right in front of us to grab a fish. This also seemed like the go to spot for bass fisherman, as we saw many trolling around the island. The Stargazer, or as my wife and I call it, the Bubble Boat, was clean comfortable and so much fun literally sleeping on the water with views all around you. It has its own small private bathroom but there were also larger public bathrooms that were very clean. The shower house was also very clean with super hot water! We are absolutely coming back!

1BSI was a really unique experience. Kent and the team had all the logistics dialed, from a restock tent to get more supplies, to coordinating pick up/drop offs. It was stress free glamping at its finest. It was easy bbqing our meals, Relaxing on the hammocks, taking out paddleboards for a relaxing cruise on the lake. Great for people who want a stress free weekend relaxing in the outdoors. At night, the dome didn’t even look like it was there and we had a panoramic view of the night sky, including all the stars. It was beautiful.
