Westonbirt is a wonderful world of trees and is beautiful at any time of the year. Set in 600 acres of glorious Cotswold countryside, it has 17 miles of paths along which to stroll and over 18,000 numbered trees, including 100 champions - the oldest, largest, tallest of that species in the world. In Spring it is ablaze with colour from rhododendrons, azaleas, magnolias and bluebells, but is more famous for its Autumn colour when it seems almost every tree turns a brilliant red, orange or gold.
