We took the bus tour from the quayside, as it was a cold windy day. The tour brought us to Dun Aengus, which you normally have to pay an entrance fee for. The access path was flooded, so we were given free tickets if we wanted to brave it. We found that removing shoes and socks, and padding through the water was the best option. It was freezing cold, but you dry off quick, and soon warm up! It was worth it for the amazing views.
