A 9th-century castle in the peak of Jomhour in the middle of Arasbaran Forrest. It is nested on a rocky peak at an altitude of 2,700 m. Babak was one of the Iranian heroes fighting the Arabs invasion, around 9th century. The road goes up to the foot hills of the Jomhour castle and from there it takes 2 hours hiking walk to get up to the peak where the castle is, but definitely worth it. The castle has an interesting military design which made it impenetrable for invaders back in the days. It has also nice view to the forests around. It is better to visit it in summer time to avoid the harsh winter weather of the Azerbaijan region.
