Our next destination was Zao-Quasi-National Park. Initially we thought to walk across the park in approx. 4 days, but the path and weather condition were unpleasant. So we got directly to Zao-Onsen after the first day by public transport and stayed for two days. Once the rain stopped we set out again to Zao-San (1841 m). However, dense fog again blocked our view to the terrific Okama caldera lake. We stayed overnight in a mountain shelter and got woken the next morning by fellow hikers, using the toilet. That must have been a funny picture for them: two Gaijins (foreigners) still sleeping in their bags while they must have been hiking for quite some time☺. Therefore we decamped and while the weather improved, we climbed Byōbu-Dake (1817 m) and Fubō-San (1705 m) before descending back down the valley to the campsite.
