Be sure to bring your camera to capture the spectacular cascades of Ginga no Taki Falls. If it's raging, you may be able to feel the mist on your skin.
When you've finished exploring this Sounkyo cascade of water, why not make your way to Sounkyo Hot Spring, Daisetsuzan Sounkyo Kurodake Ropeway, and Daisetsuzankurodake Ski Area? They're not far from Ginga no Taki Falls and also popular with travelers.
