Hill Head Harbour sits at the mouth of the River Meon on the northeastern shore of the Solent, roughly midway between Lee Point and the entrance to the Hamble River.

It marks the tidal limit of the Meon — sluice gates upstream maintain the river's water level, making the harbour itself the only section that rises and falls with the tide. The harbour dries out at low water.

A small, quiet haven, it has long served local fishing craft and pleasure boats and is now leased to and administered by Hill Head Sailing Club. The spot is also popular with sea anglers and is frequented by swans, ducks, and other waterfowl.

Titchfield Haven Nature Reserve, a coastal wetland, lies directly across the road.
