It’s an experience like none other and will make memories to last generations. Book your next houseboat vacation from 4-nights to 7-nights, and choose the boat that best suits you – accommodating up to 14 guests.

These boats can be rented at Seven Bays & Keller Ferry by the half-day, full day, or overnight.
