This is a pleasant urban park in the western part of Amsterdam. Easily reachable by bus or tram. Lots of trails, some paved. The verdant space of the former Westergasfabriek gasworks along Haarlemmerweg has become a place for cultural avant-garde businesses and events. There’s also a cool art house movie theater in a former factory. A run along the perimeter is about 3.5 miles.
