An excellent—if a bit crowded—choice for a walk is this gorge northeast of the lake at Nenokuchi. The carefully tended trail follows a river and a series of waterfalls for a total of 9 km (5½ miles; about 2 hours 40 minutes). A two-lane road parallels the river, so if you get tired you can catch buses north to Aomori and south to Nenokuchi and Yasumiya. Be prepared for cold mist or rain, pack ample snacks and water, and find out the bus schedule before you start out.
