Yes, you can bring dogs to the Aran Islands in 2026, but there are strict logistical rules for the journey. Aran Island Ferries permits pets on their vessels provided they are on a lead or in a secure carrier at all times. Crucially, dogs must remain on the outside deck and are not allowed in the indoor heated passenger cabins. Certain "controlled breeds" (as per Irish law) must also be securely muzzled and on a short lead of no more than two meters. Once you arrive on Inis Mór, Inis Meáin, or Inis Oírr, the islands are very dog-friendly for walking, but you should note that dogs are generally prohibited from the shuttle buses that tour the islands (except for guide dogs). For a 2026 visitor, bringing a dog is a great way to enjoy the rugged cliffside trails, but you must be prepared for the Atlantic weather on the ferry deck and ensure you bring enough water and waste bags, as facilities on the islands are geared primarily toward human tourists.
