Just seen the Marble Arch Caves on Nationwide on RTÉ tonight and it reminded me that I've always wanted to visit. Unfortunately I don't have a car so I'd be looking to make it there by public transport from Dublin, Belfast or Enniskillen. My problem is, despite trawling the internet, I can't seem to find any info about this. Does a tour or public transport option exist or should I buy a car?
Any suggestions appreciated!
