Saltash Passage South is a concrete public slipway situated on the east bank of the River Tamar at St Budeaux, Plymouth, opposite the Ferry House Inn.

Owned and maintained by Plymouth City Council, the slipway is approximately 6 metres wide with a moderate to steep slope and is accessible directly from the road.

It is suitable for small to medium-sized trailered boats, with parking available for only a couple of vehicles with small trailers. Unlike the nearby main Saltash Passage slipway, this one is not usable at low tide.

Boaters should be aware of potentially strong currents on the Tamar, particularly around ebb tide, which can reach up to 6 knots after heavy rainfall.

Restrictions apply near warships, submarines, and Ministry of Defence jetties along the river, and the area is regularly patrolled by MoD police.
