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.
