I’ve only been to Dublin – but it was fantastic anyhow. I truly recommend taken the DART train and going through the whole line – that is if you like scenic views – it is a great way of seeing it – and if you buy a day ticket you can stop off at all the little towns on the way – … Do stop at Howth and have some great seafood lunch … the best I’ve tasted … the seafood is really fresh …if you’re going north. Also, stop at Malahide – just have the great walk to the castle even if you don’t go in – you pass through a pretty forest walk, which kind of reminds you of a fairy tale path (except it is paved!) – and towards the south -whilst I haven’t been at Greystones – I’ve been up to Bray … quite nice to get off the train and have a bit of stroll on the beach. I didn’t stop at Dun Laoghaire – but I’ve heard it is a place to visit.
