The Guesthouse is the next best thing to camping, so if you are set on spending the night in Headlands International Dark Sky Park, you want to consider a night or two here. The Guesthouse is a secluded three-floor house with multiple bedrooms near the Lake Michigan shoreline. A night at this guest house is a one of a kind experience that you should consider. The guesthouse is reservation only, so be prepared to plan ahead.
