Visitors walking the snow-covered forest trail to Jigokudani Monkey Park in winter

Walking Trail Guide

Quick Answer

The only way in is on foot: a 1.6 km forest path from the Kanbayashi trailhead, 25–35 minutes at a steady pace, clearly marked with no junctions. It is icy in winter — boots and ice grips are mandatory, strollers are not practical.

Overview

No road reaches the Snow Monkey Park. Every visitor walks the same 1.6 km trail through cedar forest along the Yokoyu River — an easy stroll in summer and a slippery, beautiful corridor of snow in winter.

Part of what keeps Jigokudani feeling wild is that you cannot drive to it. The park sits up the Yokoyu River valley beyond the reach of any road, and every visitor — photographer, tour group, family — covers the same 1.6 kilometers of forest trail on foot. The walk is half the experience, and knowing what it involves makes the whole visit smoother.

The Basics

The trail begins near the Kanbayashi Onsen bus stop and parking area, where a wooden gate marks the entrance to the forest path. From there it runs roughly 1.6 km — about a mile — to the park's ticket office, following the river upstream beneath tall cedars. At a moderate pace the walk takes 25 to 35 minutes each way. The gradient is gentle: mostly flat, with a steady rise near the end and a final set of steps up to the entrance.

There are no junctions to worry about. One trail in, the same trail out. You cannot get lost, but you should budget time for the return leg, especially if your bus or train connection is tight.

Facilities — Use Them Before You Walk

Restrooms are available at the trailhead and again at the park entrance, but nowhere in between. The small cluster of shops near the trailhead is your last chance for snacks, drinks, and inexpensive ice grips before the forest. At the viewing area itself there are no food vendors or vending machines, so carry water — concealed in your bag, away from curious monkeys.

The Trail in Winter

From December through March, the path lives under packed snow and ice. Park staff maintain and clear it, but the surface stays slick, and the season's few injuries happen here rather than at the park. Two things keep the walk safe and pleasant: waterproof boots with deep tread, and clip-on ice grips, which are sold cheaply at shops in Nagano and near the trailhead. Our winter clothing guide covers the full checklist.

The 1.6 km forest path in midwinter — packed snow, no junctions, 25–35 minutes at a steady pace

Walked properly equipped, the winter trail is one of the most beautiful parts of the trip — silent forest, snow-loaded branches, the river running dark between white banks. Many visitors rank the walk alongside the monkeys themselves.

The Trail in Other Seasons

Outside winter, conditions are straightforward. The surface is packed dirt with occasional roots and stones, comfortable in ordinary walking shoes. Spring brings patches of meltwater and mud, summer is green and shaded — noticeably cooler than the valley floor — and autumn edges the cedars with color. Whatever the month, the gradient stays gentle.

Accessibility and Families

Children who can manage a mile each way handle the trail well, and it makes a genuinely good family walk. Wheeled access is another matter: the distance, the surface, and the final steps up to the entrance make strollers and wheelchairs impractical, particularly in snow. A baby carrier works far better than wheels here.

Timing Your Walk

Allow 25–35 minutes each way at a steady pace, and more in icy conditions. Walking in for the park's opening is the quiet hour — steam hanging over the river, the forest still, the viewing area ahead nearly empty. The return leg always takes longer than you expect; budget for it if a bus or train connection is waiting at the other end..

Tips

Allow 25–35 minutes each way, more in icy conditions. Use the restrooms at the trailhead; there are none along the trail. Ice grips for your boots are essential from December through March. The trail is one way in, one way out — budget time for both directions.
