Part industrial relic, part nature walk, this 35-hectare coastal site is remote, as you'd expect of a one-time dynamite factory. It was set up by Nobel Prize founder Alfred Nobel in 1870 and subsequently abandoned in 1984. Haunting photos inside the former director’s house depict the hard lives and close community of Catalan workers, whose explosives helped to blast the Panama Canal, Trans-Siberian Railway and Mont Blanc Tunnel. It's 3.2km north of Banyuls-sur-Mer.
The main path leads to a lovely shingle-sand beach.
