No city in the world has such a rich diversity of beautiful green spaces as London - which cover almost 40 per cent of Greater London - providing a wealth of opportunities to exercise and commune with nature year round. The capital's green bounty includes magnificent royal parks, historic garden cemeteries, majestic ancient forests, breath-taking formal country parks, expansive commons, elegant squares and enchanting 'secret' gardens, many known only to insiders and locals. London's living network of parks and gardens, commons and woodlands, canals, rivers and reservoirs, is vital to the health and well-being of Londoners (and visitors!) and makes an invaluable contribution to the quality, character and economy of the capital. It also provides food and refuge for the city's flora and fauna, which - despite living alongside some 8.25 million people - is extraordinary in its abundance, variety and scope. So, whether you're a nature lover, amateur horticulturist or an enthusiastic walker, or all three - or just seeking a bit of peace and quiet away from the stresses of life - you'll find our 20 green walks immensely rewarding. All you need is a stout pair of shoes, a sense of adventure - and this book. We hope you find them as enjoyable and rewarding as we did.
