Book excerpt: An insider's guide to the world's greatest 'secret' gardens, green spaces, and pocket parks tucked away in cities around the globe Cities everywhere are graced with charming but little-known, off-the-beaten-track gardens and green spaces, offering urbanites in the know a chance to immerse themselves in nature. These often small, well-kept secrets are not as grand as those on the tourist trail but are equally delightful and rewarding to visit, if you know where to find them. Green Escapes is the revelatory insider's guide to these secret gems. Each of them open to the public, the gardens range from pocket parks, courtyards, and rooftop terraces, to community gardens and more.
