We enjoyed strolling through St Fagans yesterday. We took the bus from the stop on Westgate. The next stop was just around the corner in front of the Holiday Inn. I'm posting because I couldn't find the round-trip fare on web sites. In case anyone is interested, it is £3.40. The driver was able to make change if necessary.
By the way, we missed a few buildings we wished we had seen because we didn't use the map to plan our route as well as we might have. Still it was a pleasant and informative experience. Don't miss the Iron Age hut!
