Staying in the Stargazer was a magical experience, even during a storm, which was happening on the first day we arrived. While the floor of the main cabin was wet, the dome stayed dry and cozy and was beautiful to experience in the rain. We were treated with cloudy days and sunny days, and they all had something special to offer. We loved swimming (yes at the end of September) and then jumping in the sauna after! All in all, a beautiful place allowing for a truly unique, and restorative experience. We will certainly be back!

Kent is an amazing host! He was so helpful getting us and our gear ferried out to the island and right to our door. We enjoyed his wonderful sense of humor and interesting snippets of history about the area. The stargazer was a magical experience that we won’t forget! We lucked out and had gorgeous clear weather so both nights we got to watch the stars from our bed. We will absolutely be back to enjoy this beautiful place of serenity.

We had an amazing two-day stay at the StarGazer dome! Kent was well-organized and provided absolutely everything we needed—we only had to pack our food and clothes. He even saved the day by lending me a charger when I forgot mine. The stargazing was breathtaking, and our dog absolutely loved the trip too. Highly recommend this unique getaway!

This is a beautiful little island. My husband enjoyed the ability to fish from just about every angle on shore as well as by kayak & canoe. Unlimited firewood, cooking utensils, grill, propane, linens, etc. made this an easy adventure.

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!
