Jigokudani Monkey Park (Nagano)

The steaming springs set in a snowy mountain may be scenic, but travelers come here to see something else -- the hot spring monkeys.
Some 200 Japanese macaque monkeys live in Jigokudani -- which translates to "hell valley" -- where the rough cliffs and onsens are covered in snow for a third of the year.
The monkeys bathe at the main onsen of the park in winter without a care for observers.
Anyone jealous of the monkey's lazy ways can head over to Korakukan Ryokan for their own thermal soak.
