Recently voted Northern Ireland's best place to live, Dundrum caught the attention of our resident border collie, Finn. Eager for a new adventure, he made his way to Dundrum Castle and found the perfect setting to explore.

Nestled in the picturesque landscapes of County Down, this historic site offers stunning views, wide open spaces, and a network of trails ideal for curious noses and enthusiastic tails.

Why Dundrum Castle?

Dundrum Castle is a slice of history perched high up, offering panoramic views of Dundrum Bay and the Mourne Mountains. While your dog might not appreciate the history lesson, they’ll certainly enjoy the fresh air and wide-open spaces. It’s the kind of place where wagging tails meet tranquil vibes.

The Trails

We parked at the Castle Car Park, where breathtaking panoramic views of Dundrum Bay greet you. Heading toward the northwest corner of the car park, you'll find the entrance to the Wood Walk, marked by an interpretative panel.

Route from Dundrum Castle Car Park

From there, a 70-meter flight of steps descends a steep slope before rising again. At the far end of the woods, a pedestrian stile connects walkers to the green lane, offering a return route to the car park and completing the trail.

The trails around Dundrum Castle are a walker’s paradise, ideal for dog owners. Whether you’re seeking a relaxed stroll or a more vigorous hike, there’s a path for every preference:

The Woodland Path: This shaded trail meanders through a small forest near the castle grounds, perfect for dogs who enjoy exploring every scent along the way.

The Castle Circuit: A shorter route encircling the castle ruins, this is an excellent choice for older dogs or when time is limited but you still want a scenic outing.

The Coastal Viewpoint: For the adventurous, take the trail leading to the viewpoint for stunning vistas of the bay. Be sure to keep your dog on a lead, as the rugged terrain requires caution.

Here are some pointers to make your visit to Dundrum Castle as smooth as possible:

Bring the essentials: Water, poop bags, and a sturdy lead are a must. While the trails are dog-friendly, and there is a dog waste bin at the entrance of the castle car park, there are no dog bins near the castle, so be prepared to carry waste until you find one.

There is a toilet block and picnic tables for those wanting to stay a while.

Check the weather: The trails can get muddy after rain, so wear sturdy footwear. Your dog probably doesn’t mind the mud, but you might!

Respect the ruins: The castle ruins are a piece of history, so while you’re free to explore, make sure your pup doesn’t climb or chew anything they shouldn’t.

Mind the livestock: Some trails near the castle pass through fields with grazing animals. Keep your dog on a lead to ensure everyone stays safe.
