Pembroke Dock, or The Port of Pembroke, is the third largest town in Pembrokeshire. It originally grew up around the Royal Naval Dockyard. As part of a chain of fortifications along the Haven to defend the Dockyard, two Cambridge Gun Towers were constructed to the west and east sides of the dockyard. These are known as the Martello Towers.

Today the former dockyard is a commercial port and a gateway by ferry to Ireland. Irish Ferries operate a ferry service from Pembroke Dock to Rosslare in southern Ireland. The ferry runs twice a day in the early afternoon and the early hours of the morning.

The Pembroke Dock Heritage Centre based in the Garrison Chapel recounts the towns link with the Sunderland flying boats. Meander along the waterfront and visit one of the local historical pubs on Front Street overlooking the historic Martello Gun Tower.

A range of coffee houses, cafes, restaurants and takeaways can be found in the grid- like maze of streets in the town with further choices to be found in the nearby town of Pembroke.

The Pembrokeshire Coast Path crosses the Cleddau Bridge and across the waterfront past the Martello Tower on Front Street before heading uphill on the way to Pembroke. The character of the coast path around the haven is very different to that around the more rugged coastline.

The South Pembrokeshire Golf Club occupies a superb location above Pembroke Dock with fine views over the Milford Haven waterway.

Pembroke Dock is connected by several bus services linking to Haverfordwest, Milford Haven and Tenby. Pembroke Dock also has a railway station.

Two primary schools provide primary education in Pembroke Dock itself - Pembroke Dock Community School and Pennar Community School while Harry Tudor School, located between Pembroke Dock and Pembroke, provides secondary education for 11-18 yr olds.
