Notes from a small island by Bill Bryson tells the story of Bryson's last trip around Britain before moving back to the States after almost 20 years on the British island.
The book is packed with interesting and funny stories about travelling as it really happens. By reading the book you get a nice insight into the life of the British people and their peculiarities. Some places Bryson visits on his trip are: Bradford, Edinburgh, Exeter, Glasgow, Llandudno, London, Porthmanog and Thurso.
This book is definitely a must-read for everyone before or after a trip to Britain.
If you like to explore Pembrokeshire by public transport I recommend to take a copy of "Getting Around Wales (Crwydro Cymru)". It provides timetable infomation about rail services, all kind of bus and coach services and air services from Cardiff Airport.
The timetable book is published by "Southern Vectis" and it is available at the Tourist Information.
Miscellaneous: To explore Great Britain an up to date guidebook is very useful. I often use the Rough Guide to Britain (England, Wales, Scotland). It covers information for all budgets on the best places to stay, eat and drink. Plenty of recommendations and practical tips on exploring the countries make this book an useful travel companion.
