1. Yanar Dag, also known as the \"Burning Mountain,\" is a natural gas fire phenomenon located on the outskirts of Baku, the capital city of Azerbaijan. The name \"Yanar Dag\" translates to \"burning mountain\" in Azerbaijani. It is one of the most famous and unique tourist attractions in the country.

The flames at Yanar Dag have been continuously burning for several decades, fueled by natural gas, which seeps through the ground and ignites upon contact with air. The flames reach heights of up to 10 feet (3 meters), and the constantly burning fire creates a mesmerizing sight, especially after sunset.

The Yanar Dag area is believed to be the result of ancient hydrocarbon deposits, which have been burning for centuries. The flames are said to have first ignited when a shepherd accidentally set the mountain on fire. Local legend suggests that the fire has been burning since the 1950s, when it was accidentally lit during a Soviet-era oil exploration.

2. Yanar Dag is open to visitors every day, and there is no specific working time or entrance fee. The site is accessible 24/7, allowing visitors to witness the flames at any time of the day or night. However, it is recommended to visit during the evening or night to fully experience the spectacle of the burning mountain.

Unfortunately, there is no specific phone number available for Yanar Dag, as it is a natural phenomenon and does not have a dedicated visitor center or management office.

3. To reach Yanar Dag, you can take a taxi or a bus from Baku city center. The journey takes around 30 minutes by car, depending on traffic conditions. It is also possible to hire a private tour guide or join a guided tour that includes transportation to Yanar Dag.
