In the old days, the road became too rough for horse riding, so riders had to alight and proceed on foot; the lake is 4,165 feet above sea level. From Umagaeshi the bus climbs a one-way toll road up the pass; the old road has been widened and is used for the traffic coming down. The two roads are full of steep hairpin turns, and on a clear day the view up and down the valley is magnificent—especially from the halfway point at Akechi-daira (Akechi Plain), from
which you can see the summit of Nantai-san (Mt. Nantai), reaching 8,149 feet. Hiking season lasts from May through mid-October; if you push it, you can make the ascent in about four hours. Wild monkeys make their homes in these mountains, and they've learned the convenience of mooching from visitors along the route. Be careful—they have a way of not taking no for an answer. Do not give in to the temptation to give them food—they will never leave you alone if you do.
