Hi all, looking to hear from anyone who may have done the Asahidake Onsen to Sounkyo hike via mount Kurodake. My goal is to do it in one day, starting from asahikawa and then sleeping at Sounkyo before returning but it seems like a long hike and i dont want to push it (20.7km and 1500m elevation). Has anyone done anything similar that might have some advice or tips for me? THanks!
