30 kilometers west of Astara in Gilan province on the road Astra to Ardabil the Heyran tourist region is situated.
This region consists of three villages called lower-middle and upper Heyran and the pass to these villages is one of the most important tourist attraction and It faces the forest-covered mountains on the one side and a valley on the other side where the Aghchai River flows and forms the border between Gilan Province and the Republic of Azerbaijan.
This Pass is covered by fog most of the time although it is not of very great height (the highest point is about 1500 meters above sea level). The main reason for this permanent fog cover is the moisture coming from the Caspian Sea.
Half of the forests and the pastures in this region belong to Iran and the other half to the Republic of Azerbaijan.
There are many tourist facilities and the unique one is cable cars at heyran pass. The cable cars travel a distance of 1500 meters and stop at the Fandoglu Forest.
