Wrapping itself around the Botanic Gardens, Hagley Park is Christchurch's biggest green space, stretching for 165 hectares. Riccarton Ave splits it in two and the Avon River snakes through the north half. It's a great place to stroll, whether on a foggy autumn morning, or a warm spring day when the cherry trees lining Harper Ave are in flower. Joggers make the most of the tree-lined avenues, year-round.
