Teenagers along the trail up the slopes of Tochal..Darband is a northern suburb of Tehran and a popular place to visit for Teheranis. People spend their day on the steep walk along the river. The initial start of the walk at Darband is about 250 metres long and is dotted with a number of small cafes, restaurants, shops and hooka lounges (locally called ghavekhane sonnati). The trail is the beginning of a very popular hiking trail into the Alborz mountain Tochal, which towers over Tehran..April 13, 2007.Credit: © Guido Van Damme/ 2007
