I will be in Cardiff for 2 ½ days and 3 nights. One of the sites I'm interested is the Rhondda Heritage Park (Coal Mine). My first question is the tour worth the time and cost. Second I understand that if you do not have an automobile you can walk or take the bus/train. I will be staying in the Hotel Clanton on Saint Mary Street; any suggestions on going to and from Rhondda Park?
What is the weather like this time of the year and any suggestions on clothes to pach.
