Fukui Sta. (Hokuriku Line), 25min bus; or, Ichijodani Sta (Etsumihoku Line), walk
There are three trails to the top of the mountain. The most convenient ones for visitors by foot are probably the Umadashi Trail that starts on the north end of the castle near the Hachiman Shrine and the other is from behind the Asakura Yakata starting from near the Eirinzuka. With an elevation gain of 440m (according to my GPS) all the way to the highest point, this is one of the higher climbs I've done to get to a castle. I'm not sure if it was from the recent rains or if this area, famous for its natural springs, is always like this, but the trail was very wet, muddy and slippery the whole way. Near the top I passed a middle-aged couple who looked like they had just stepped off the golf course in their Sunday drive outfits, covered in mud from feet to knees and hands to elbows. No hiking boots or trekking poles. They had started about 30 minutes before me, but were in good spirits when we found out it was almost the summit. It's a good steep climb but the trails are well maintained and easy to follow with plenty of signs. I still recommend good hiking shoes and a trekking pole. There are also signs warning of bears so a bear bell is also recommended. This last point of advice was also strongly reiterated to me when I rented my bicycle and said my first destination was the mountain castle.
