As one of the biggest attractions of Hamadan province and the world’s largest water cave,
Alisadr is ranked among the most popular sites of Iran with thousands of visitors year-round,
especially in spring and summer.
This cave is located in Kabood Ahang , a city 60 Km from Hamadan.
The distance from Kabudarahang to Alisadr Village is 50 Km.
This cave is located on the elevated lands of Sari Qieh, meaning the yellow rock.
Evidences prove that during the Safavid period (16th c) , locals used cave water through
hand dug canals but they did not know anything about the cave until 1963 when a group of
14 climbers got responsibility to discover the cave’s length, width, depth and height
by entering a narrow entrance of about 50 cm which leaded to one of the main caverns.
This hole that only professional climbers could get through it, remained as the only
access to the cave’s inside, until 1974 when Abdullah Hajilo, who headed
the Hamadan Mountaineering Board, expanded its width by 5m with the help of locals.
The following year, they founded a concrete platform set for walking visitors, and with
the provision of lighting facilities, Ali-sadr was prepared for public visits.
