Dublin has much to offer from the GAA Museum & Skyline at Croke Park to the new Aviva Stadium, from Kilmainham Gaol to the Dublinia Viking and Medieval Exhibition, any visit is always an education! A guided walking tour of Dublin is an excellent way to see the city or how about an amphibious alternative with the Viking Splash Tour! A visit to the Sealife Centre in Bray with its Giant Pacific Octopus feature is an education in itself.
