At the St. Pauli landing stages in Hamburg is the Wallringpark, a large recreational area that includes some of the city's most popular open spaces, such as the Old Botanic Garden and the Kleine and Grosse Wallanlagen, the gardens laid out on the line of the old fortifications.
The best of these excellent parks is Planten un Blomen, a 116-acre park established in 1821 with the planting of a Platanus tree that can still be seen here.
It's a wonderful place to relax and enjoy a picnic, or if visiting at night, take in the famous water-light concerts or a musical performance.
