Another of the "About Wales" pocket books, "About North Wales" focuses on the mountains and castles in Snowdonia as well as the busy towns of Llandudno and Rhyl.
This book is great for planning a trip to North Wales as it includes details of local festivals and events. Lots of pictures link in with the text to show you about North Wales rather than just tell you.
I found this book and the others in the series very helpful for planning my trip to Wales, but they are also interesting to just read and learn about the country.
