Trebević () is a mountain in central Bosnia and Herzegovina, located to the southeast of Sarajevo, in the territory of East Sarajevo city, bordering Jahorina mountain. Trebević is tall, making it the second shortest of the Sarajevo mountains. During the Middle Ages, Trebević was known as Zlatni Do. During the 1984 Winter Olympics Trebević, like the other Sarajevo mountains, was used for a number of Olympic events, such as bobsledding. Trebević today is important as a tourist destination for citizens of Sarajevo as Igman or Bjelašnica. Most of the land mines are now cleared from heavy fighting that took place in the early 1990s. There are a few hotels, mountaineering homes, and other such structures on Trebević and the immediate area. The mountain is very popular for family picnics, hiking, climbing, mountain biking and it has a downhill track for local and international skiing competitions. Trebević has been the main excursion site for Sarajevo citizens due to the favorable geographical position, climate and the beauty of the nature.
