Haven ZWV Noord Aa is the marina and access point of Zoetermeerse Watersportvereniging Noord Aa, situated on the Zoetermeerse Plas within the Noord Aa recreation area in Zoetermeer.

The club's harbour offers moorings for both sailing boats and electric-motor fishing boats, with storage available for surfboards, kayaks, canoes, and SUPs, as well as space for boat trailers.

The Zoetermeerse Plas itself is a deep sand-extraction lake, reaching 25 to 30 metres in places, and is centrally located near Leidschendam-Voorburg, Den Haag, Leiden, and Rotterdam.

From this access point, members can pursue a wide range of water sports including sailing, windsurfing, kite surfing, canoeing, and dragon boating.

The site is also a known scuba diving location, with peat walls, reed banks, submerged car wrecks, and varied marine life — including pike and eels — found beneath the surface.
