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.

The vastness of the Mourne Mountains also allows for a sense of solitude even on more frequented trails.
