The Solvay Regional Estate in La Hulpe is affectionately called the "Park of a thousand rhododendrons", and is one of the loveliest places for a stroll in the country.Lawns, woods, rhododendron beds, and remarkable varieties of trees enhance some 227 ha. This magnificent wooded park just outside Brussels boasts paths around and over tree-lined hills and ponds with exceptionally rich animal life.It is also home to Béthune castle, built in 1842 using the Loire castles as a model, and its French gardens with decorative sculptures.
