4.00Very nice tour of the Cardiff area, enjoyed Caerphilly most of all. Castle Coch was surrounded by scaffolding and we were told we’d get to see a fourth castle to make up for it, but that didn’t happen. Still, a lovely day and a great chance to see areas around Cardiff. Our tour guide was informative, and the time spent at each location was good.
Just do the tour - a must

5.00I’ve just got back from a tour of South Wales with this company, and wow, it was amazing! The whole tour was well organised which made everything smooth and easy. I saw some cool historical spots, including Tintern Abbey, and the views were out of this world – think postcard-worthy scenery at every turn. The driver guide was a legend – so warm and welcoming and knew loads about where we went, filling the day stories that made each place come alive. It felt more like a day out with friends than a sightseeing tour. Thanks for such a fantastic day!
