Bois de la Cambre, Brussels
Concierge.com's insider take:
At 272 acres, Bois de la Cambre is Brussels's biggest park. This central spot is a delightful place to spend an afternoon strolling around its woodland paths. Highlights include a large lake with a small island at its center (reached by a cable-drawn ferry) which is popular for picnics. The ferry is currently closed for renovation until 2008, but the park is still well worth a visit.
