It's great that you are visiting the Aran Islands next month !
First of all, which one of the Aran Islands will you be visiting ?
Assuming you arrive on Inishmore (the biggest island of the three) , there are plenty of accommodation options near the ferry port. You might want to look into hostels (such as Kilronan Hostel
) since you are looking for an affordable place to stay. Furthermore, here are more accommodation options
in County Galway
Renting a bike could also be an option, it's a fun way to explore Inishmore during your time here and you could reach other accommodations further, given that you are travelling light.
Let us know what you think. :)
