Fodor's Expert Review Westonbirt National Arboretum

Spread over 600 acres and with 17 miles of paths, this arboretum contains one of the most extensive collections of trees and shrubs in Europe. A lovely place to spend an hour or two, it's 3 miles southwest of Tetbury and 10 miles north of Bath. The best times to come for color are in late spring, when the rhododendrons, azaleas, and magnolias are blooming, and in fall, when the maples come into their own. Open-air concerts take place in summer, and there are exhibitions throughout the year. A gift shop, café, and restaurant are on the grounds.
