Agha Seyyed Isa Cave

Agha Seyyed Isa Cave is located in Chaharmahal and Bakhtiari Province, in Farsan County, about 10 kilometers west of Farsan and near the village of Bidgol. The cave is part of the well-known "Agha Seyyed" recreation area. Besides its natural features, it has religious and cultural importance, and every year locals and tourists visit it to pray and make pilgrimage. The cave lies in the Asmari limestone formation. It is more than 330 meters long and has intricate passages and numerous chambers.

Inside the cave there are several low-ceilinged chambers. The first chamber has a larger space and is often used for cultural and religious gatherings. The route through the cave is complex and sloping (up to a 30-degree gradient), with a narrow passage, formations (stalagmites/stalactites), a natural lake and a seasonal spring deep inside. There is also a small internal waterfall, 5–7 meters high, which divides the cave into an upper and a lower chamber. Bats live in the depths of the cave, and the natural gases inside it sometimes kill them. Therefore, following safety precautions is essential.

The cave is reached via the Farsan–Chelgerd road and then a dirt side road to the village of Bidgol; the route is about 44 kilometers of paved road and 1 kilometer of 4x4 track to the entrance. Near the entrance, a stone staircase and terraces have been built for resting. The best time to visit is spring and summer, when the weather is cool and pleasant. We recommend following caving etiquette, taking your litter with you, not damaging the stalactites and stalagmites, and respecting the religious areas, so you can enjoy your trip.
