i'm visiting britain in the summer and i would really like to visit wales since i've never been there before. the problem is i havent figured out how to get from london to north wales even though i have done a lot of net research. we wont have a car so i would like to know what is the most reliable and quick way to get from london to betws-y-coed using public transport.
also i would like to know what is the weather like in August on average in North Wales. will we need warm clothes?
