The resident grey seal colony is accustomed to human presence and often congregates near the fishing boats.
The 12th-century castle ruins overlooking the harbour were part of a defensive network protecting cargo offloaded from ships.

Bullock Harbour is a working, historic stone-walled harbour located in Dalkey, County Dublin. The harbour was constructed in the early 19th century and remains a hub for local lobster and crab fishermen. The site provides unobstructed views across the Irish Sea towards Dalkey Island and the Muglins rock. It serves as a departure point for small recreational craft and sea anglers. The surrounding area features the ruins of a 12th-century Cistercian castle tower, which was originally built to defend the harbour from pirates. The harbour basin is tidal, and the water levels fluctuate significantly throughout the day. It is a popular spot for outdoor swimming and seal spotting, as the resident seal colony frequently gathers near the slipway. The stone piers are built from local granite and retain much of their original structural design.

Bring sturdy, non-slip footwear as the stone piers can become slippery, especially at low tide.
Keep a safe distance from the seals, as they are wild animals and can be protective of their space.
Check tide charts before planning a visit, as the harbour's aesthetic changes dramatically between high and low tide.
Avoid walking onto the slipway when boats are actively maneuvering or docking.
Respect the work of local fishermen by keeping walkways clear of gear and equipment.
