Jigokudani Monkey Park, Nagano, Japan
The park is open all year round, but it’s the prettiest – and most photogenic for aspiring wildlife photographers – during winter months. Japanese macaques, also known as snow monkeys, play about in the white landscape before relaxing in the steaming outdoor baths. As tempting as it might be to join in, head to nearby hot-spring towns Shibu and Yudanaka instead to splash about in your own onsen.
