I received this book with some eagerment, expecting to find a detailed, am more importantly ACCURATE review of caves in South Wales. Unfortunately, if I'd used this book as the basis for some recent cave expeditions I would have become lost!
The details contained are somewhat sketchy. For example on a recent SWC expedition to "Cwmtaff" the information was inaccurate! Not only were the distances hopefully inaccurate, the reader is given no warning of a 40 foot drop at the end of the first cavern!
We also used the book as a reference to Mer-Dalybont cave with similar results-the book was just plain wrong some of the time.
That said, the book does provide a lot of useful info to the novice caver.
