The best wildlife-watching opportunities are in springtime, while increased rainfall through autumn and winter makes the wild landscapes appear even more dramatic. Summer is peak season at Wicken Fen, and the boardwalks can get crowded, especially on weekends and school holidays. The reserve is open year-round, but boat tours and bike rentals are only available from Easter through October. Wicken Fen National Nature Reserve is located in Cambridgeshire, about a 40-minute drive from Cambridge.
