The pure waters of the Akan River are home to rainbow trout and whitespotted char. In winter, you can hike on snowshoes through the snow-covered forest by the river. Hot springs can be found along the river, making the perfect end point for your hike. If the timing is right, you might even see wildlife such as foxes, raccoon dogs (tanuki) and Yezo deer, which drink from the hot springs to get minerals.
