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 ruined round tower marks the site of an early church founded by the 6th-century St Domongart (Donard), after whom the highest peak in the Mourne Mountains is named. The tower stood to its full height until the early 18th century, when it fell in a great storm, It is built of local granite boulders and shale. Small scale excavation in 1965 showed evidence of Early Christian activity near the tower. In the oval graveyard east of the parish church is the ruin of the medieval parish church, probably 13th century in date.
