Walking tours, as the term implies are cultural tours which involve walking. Pub Crawls, on the other hand, usually involve a more horizontal form of walking–whether the participants intend this or not.
And then there is the Literary Pub Crawl. This would be a combination of the above where scholarly and inebriated meet head on, in a collision of grey matter and sudsy matter.
As far as I know, there is only one city on this planet that offers such high-brow/low-brow activity. This would of course, be Dublin.
Dublin’s Literary Pub Crawl retraces the steps of Ireland’s most famous writers–Oscar Wilde, James Joyce, and Samuel Beckett among others–as they sallied forth from one pub to another. The tour is lead by a group of actors who portray the illustrious scribes and takes 2 hours to cover eight pubs and Trinity College. The price is €8 per person and no, it does not include beer.
