Hi Jodie! Welcome to the forum. :)
Our member Doolin2Aran Ferries has the perfect answer to your question, you can read up on it on this thread
. There are a lot of fun things to see on the Aran Islands so you might want to take your time there. On the biggest of the three Inishmore, you can find the prehistoric fort Dún Aengus
. It lies just on the edge of the cliffs and you have some amazing views from there.
The famed Aran sweaters originate from these islands too, every fisher family had their own pattern.
