We had a group of 29 (half adults adn half kids). The property is perfect for large group. Great decks with views of the lake and woods, horse shoes, a massive commercial kitche with a walk in fridge, laundry, a 2 story game room, and it's only 20 minutes outside of WhiteFish. There's a lake with canoes and kayaks on the property. The bottom is muddy so it's best to canoe out into the middle and swim there. There was also a lake just north of the house with some fun cliff jumping that the kids loved. They also had several bike, a huge grill, a fire pit, etc.
The staff was amazing and Sarah helped us get everything planned in advance (hikes, catering, extra cleaning, babysitters, etc.). I would highly recommend this place to anyone!
