Anglesey offers very different dog breaks: Beaumaris for a castle and seafront stay, Menai Bridge for a gentle Strait-side outing, or Holyhead for a more exposed coastal day. Dog access changes between castle interiors, beaches, gardens and reserve buildings, so choose your base around the places your dog can actually join.
Beaumaris suits a short break where the castle and seafront provide the shape of the day. Both reviewed inns are on Castle Street, so you can keep the plan local and avoid driving for every outing. The useful distinction is in the room allocation and dog dining arrangements, rather than the distance between the hotels. Build the castle visit around its permitted ground-floor areas and treat the beach separately from the promenade.
Holyhead can be more than a ferry stop when you leave time for an outdoor coastal day. Choose a waterfront-area hotel or a practical Travelodge base, then decide how much exposure and walking you want. South Stack offers a reserve visit with clear dog rules; the longer Holyhead Mountain route is an optional active day, not an essential part of the break.
Menai Bridge works for a gentle Strait-side break with the option of an estate day nearby. Start with Belgium Promenade and the Church Island approach, then leave Plas Newydd for a separate outing. Both hotels are in the town, but the exact dog room must be agreed: a pub welcome alone is not a room reservation. Choose the stay after confirming dining and supervision arrangements.
Choose the kind of outing that fits your trip: a compact castle-side town, the Menai Strait and a separate estate visit, or a coast and reserve day with a more active walking option.
Choose a Castle Street base for the castle and seafront. Dogs can join only permitted ground-floor areas inside Beaumaris Castle; check beach restrictions separately from promenade access.
Choose Belgium Promenade and the Church Island approach for a gentle Strait-side outing, then make Plas Newydd a separate visit. Pet dogs are excluded from the house and Italianate and Terraced Garden.
Choose Holyhead for a coastal reserve day at South Stack, with Holyhead Mountain as an optional, more demanding walk. The café excludes pets, so plan a dog-compatible pause elsewhere.
