Picton Marina sits at the south-eastern head of Picton Harbour, within the heart of Waitohi/Picton township, in an area originally known as Kaiaua Lagoon.

The lagoon was reclaimed during the 1960s to create the marina, which now serves as a gateway to the Marlborough Sounds cruising grounds.

The marina accommodates vessels from eight to 35 metres and beyond, with permanent and visitor berths available following a recent expansion that added premium berths for larger vessels.

Facilities include toilets, showers, laundry, water access at all wharves, rubbish disposal, fuel, and 24/7 CCTV security with after-dark patrols. Pier access is managed via security cards.

Local shops, restaurants, and foreshore markets are all within easy reach of the marina.
