The head of this bay dries at low tide.
Good anchorage in all but SE winds can be found for about three boats in the cove on the northern side.
A stern line is recommended.
The anchorage to the south of Waterfall Bay is good shelter in SE to W winds.
There is public road access to Waterfall Bay, which leads from the Port Marlborough wharf at the head of the north-west arm of the bay.
It is a brisk half hour walk to Te Mahia. When reaching the Havelock road at the saddle, turn to port and the road to Te Mahia branches off to starboard a short way down the hill.
Vessel speed is restricted to 5 knots with a 5 knot speed buoy.
