Carrickfergus Marina sits on the north shore of Belfast Lough in County Antrim, Northern Ireland, overlooked by the town's 12th-century Norman castle.

The harbour itself has roots dating to 1127, when it was built alongside the castle, and has since grown into a well-regarded sailing destination within the Belfast Metropolitan Area.

The marina offers purpose-built pontoon berthing, a boatyard with repair, lift-out, and refuelling facilities located on the southern end of the west pier, and an inner harbour area with a public slipway accessible around high water.

Visitors benefit from 24/7 access at any state of the tide. The surrounding waterfront provides restaurants, shops, and leisure amenities within easy reach.

Incoming vessels should contact the marina office on VHF Channel 80 prior to arrival for berth allocation.
