Millisle Lagoon
County Down
Millisle Lagoon is a charming curiosity on the Ards Peninsula coast in County Down — a small sandy beach that forms a natural seawater lagoon, complete with an old outdoor tidal pool that gives the spot a nostalgic, old-fashioned seaside feel. The setting is sheltered and compact, tucked away from the more exposed stretches of the Ards coastline, making it a calm and contained spot for a coastal visit.
Dogs are welcome year-round at this dog friendly beach, and the sheltered lagoon provides unusually calm water for dogs who enjoy paddling but are nervous of waves. The sandy ground is easy on paws, and the enclosed nature of the site means anxious dogs or those with unreliable recall can enjoy the beach with less stress. It suits a shorter, relaxed visit rather than an epic beach walk — perfect for older dogs or those who prefer pottering to sprinting.
