Nestled deep in the trees in a picturesque cove along the Lake Winnebago shore is a place where all AirVenture visitors should try to visit: the Seaplane Base, where the runway requirements specify depth as well as length.
Buses make regular runs between the AirVenture grounds and the Seaplane Base, departing from the Bus Park Tower just outside the Main Gate and the Amphib Parking area at the south end of the airport ($3 round trip for this shuttle).
Seaplane base pace offers a respite from AirVenture's hustle and bustle. People often just sit on the shore and watch the planes come and go.
The Watermelon Social is the Seaplane Base's big annual event, held on Saturday night.
