Japan
Snow monkeys soaking in a hot spring while the snow piles up on their heads.
The monkeys arrived first. In the Yokoyu River valley of Nagano, Japanese macaques have been watched soaking in the hot spring since 1964, long before anyone thought to sell a ticket. In winter they sit in the steaming pool with snow settling on their heads, grooming each other with the studied indifference of regulars at a spa who have seen it all before.
Jigokudani โ Hell Valley โ sits at 850 metres in a gorge of steaming vents and lies under snow for a third of the year. The park was set up so that wild macaques could be watched with no fences and no cages: the monkeys live in the surrounding forest in troops numbering hundreds, come and go as they please, and on some days do not come at all โ the park posts a weekly appearance forecast. December to March is when they bathe. You walk in, along a two-kilometre forest trail from Kanbayashi Onsen, a walk of half an hour or so that is passable all year and needs proper boots and, in winter, simple crampons. Ten minutes down the valley, Shibu Onsen has been a hot-spring town for 1,300 years, and its nine public bathhouses are toured in a yukata with a towel you stamp at each one.
Family
Children cannot look away from the bathing monkeys โ the babies clinging to mothers, the elders closing their eyes in the steam โ and the forest walk is manageable for young legs, with Shibu Onsen's baths to follow.
Couple
Watching the monkeys soak while snow falls is quietly hypnotic. An evening touring Shibu Onsen's stone-lane bathhouses in yukata completes a day of warmth against cold.
Solo
The winter forest trail, the silent observation of the troop's rituals, and a solo circuit of Shibu Onsen's nine bathhouses make this a contemplative day from Nagano.
