It's got surfing; live music; and some really nice, inexpensive places to eat and sleep. I love this town -- I've been a few times and it's always fun and really charming.
Bundoran is a beautiful place. I've been there twice and am going again in July. The beach is deadly. You can't beat Bundoran.
I recently visited Bundoran and had a wonderful time -- went to stay for one day and ended up staying for four. There is a lot of beautiful walks around the beaches and some excellent traditional music in the pubs in the evenings.
Bundoran is a beautiful area by the beach, but unfortunatly I find it a little dirty sometimes. Overall I think it's a lovely town and most of the people are sweet and kind.
