While the hike can be vigorous, many find it rewarding and a must-visit for history enthusiasts. Parking and accessibility are key considerations for planning.
"It’s a beautiful hiking trail to the castle ruin site. It’s far from the ota station so I took a taxi to the guidance center. From there it took about 40ish minutes to climb. It’s very doable but I would say it’s vigorous course.
Stamp is located at the final rest area not at the guidance center. But if you want to buy gojoin like castle’s calligraphy you need to buy at the guidance center."

Amazing ruins and unique structures, definitely worth spending a couple of hours here."
