Dating back to the 19th century, this historic port offers an authentic insight into the region's maritime history. The well-maintained paths along the port make for a pleasant ride with views of the Mourne Mountains in the background. However, it can get slippery in wet weather, so care must be taken. A particular highlight is the Annalong Cornmill, a restored watermill that is well worth a visit. Nearby you'll find the Harbour Inn, a cosy eatery known for its fresh seafood. Note, however, that the harbour can dry out at low tide, which changes the view.

The small, historic port provides a charming setting with views of the Mourne Mountains and the sea. The promenade is well maintained and is great for a relaxing cruise along the coast. However, it can get quite busy in good weather and at weekends, which can slow down the journey. A highlight is the proximity to Murlough National Nature Reserve, which is just a few kilometers away and is ideal for further exploration. Note, however, that some sections of the promenade can be slippery when wet, so care must be taken.

Now wonderfully restored, the mill features an exhibit where you can experience how life in the past could have been like on the Mourn Mountains, and surroundings.

The lovely little harbour was historically the heart of the community. At its height shipping the quarries work put in on reshaping the surrounding hills to the UK and Ireland. But those days are dust You will however still catch a few classic vessels passing through, as they make their way down the South Down coastline. All of which you can cycle. I recommend that.

If you fancy a dip after all those hills, this is a very safe spot for swimming. The slipway at the side of the harbour wall is the preferred entry point. If you look back along the side of Slieve Donard, you will see some cottages known as “Widows Row”. These were built for the widows of fishermen who died at sea. They would be able to live out their days in one of the cottages looking out to sea.
