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.

In mid-April, you are greeted by a wonderful scent that comes from the flowering bushes beside the path - perhaps laurel? The fresh breeze mixes with the intense aroma that gives nature something very special. The bridge itself is surrounded by a quiet forest, which makes the crossing seem like a small oasis of relaxation. A brief moment that invites you to take a deep breath before heading back out onto the road.

Nendrum Monastery was a Christian monastery founded in the 5th century. The monastery finished somewhere between 974 and 1178, but the church survived until the 15th century. You can visit the ruins if you're riding past.
