A fantastic book we were recommended to purchase as part of our Outdoor Education degree. This book has all you could possible need to know before setting out into the hills around the UK. Covering all the topics needed for Mountain Leader and Walking Group Leader Schemes, it's essential reading but still easy to read. Colour pictures and photographs compliment the text well.
A useful 'bible for the outdoors' even if you're not working towards certification. If you enjoy roaming the hills this will teach you proper methods of navigation, survival, wild camping, protecting the environment, trip planning and incident handling.
There is another long standing classic book on the market called 'Mountaincraft and Leadership' by Eric Langmuir. This is a much more in-depth book on the same topics. Also a brilliant and highly recommended read but slightly harder going. If you were only going to buy one book on the subject then this book ('Hillwalking: The official handbook of the mountain leader and walking leader scheme's' by Steve Long)would be the one to buy. If you have the money though both books are very useful. I take my Steve Long book with me on trips and have the Eric Langmuir book on the shelf if i need to know a little more on a subject.
In conclusion, buy it! The price on Amazon was the best i found online and enjoy many safe journeys around our wonderful, awe-inspiring mountains.
