I'm going to Belfast for the weekend in July and would like to visit the Giant's Causeway. Can anyone recommend a company to do this with? I'd quite like a smaller, more personal tour but all of them seem to be big coach groups. Also, has anyone done the black cabs tour of the city centre? It sounds great but I'm not sure whether the city sightseeing bus might enable me to take in more of the city.
Mainly Giant's Causeway is an impressive geological phaenomeno/scenic place and personaly I don't find a guide a necessity. I do not know if there are guides available on site on summer months as I always travel off-season, but visitors' center provided a decent leeflet with walking routes and basic info.
I can not help you with up to date details, as my last visit was some years ago, but you may find the public bus schedules searching here: http://www.translink.co.uk/ I have visit GC a couple of times, always on the public bus and I enjoyed the journey, bus was stopping by scenic Antrim coast villages so it was interesting scenery and scene to watch almost all the way and people watching is not bad either, this bus line used mostly by locals embarking/disembarking here and there.
