h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

The Liffey walk is a brand new boardwalk (except made of steel) along the Northen bank of the River Liffey, in Dublin. The walk in the day is nice in that it gets you away from the terrible traffic, but it is best experience at night - the lights from all the buildings reflecting off the river, and the coloured lights on the bridges combine to make the river shimmer in a thousand colours...

Another good walk in Dublin is from Lansdowne to the Beech - see http://www.h2g2.com/A322039
