This might be a good idea to visit on a rainy day, but to be honest in my personal opinion Aillwee Cave is not really worth to spend any time when the weather outside is good !
They make a lot of advertisment and all over Ireland you may get their brochures and when you are finally there, you will just walk inside a cave and see places, where obviously bears hibernated a very long time ago. And around that simple fact they constructed a gigantic program, light-effects in the cave etc.
Aillwee Cave is open for visitors daily
all year long after 09.30a.m.
entrance-fee is 9 Euros / children : 5 Euros !
Other caves in the area are: the Doolincaves
Some of the best caves in Ireland (or as the tourist info puts it "Ireland's premier showcave" - whatever that may mean!) the Aillwee caves are definitely worth a visit
If you think the Burren is impressive looking above ground then check it out below where the caves are full of spectacular rock formations.
The caves are open all year round (from 10.00am to 6.00pm with last admissions 30 minutes before closing) and cost €7.50 for adults (€4.50 for children with reductions for students & OAPs). Family tickets are also available
