Plaat van Oude Tonge: boat-only dive with mussel strings.
Boat-only site; local dive boats normally handle the trip and timing.
Plaat van Oude Tonge is a boat-only delta dive with a sloping seabed, mussel strings and shell-covered relief that keep the route interesting from the first drop. Divers usually work out from the boat toward the old village remains and the hanging mussel lines, so it suits people who are comfortable with boat timing, variable current and fair-weather surface traffic.
