Borj is near Tehran, capital of Iran. Climbing in summer is relatively easy in just one day. The route begins in Laloon village in Fasham region. This peak almost is center the highest peak in central Alborz which its name is Kholenoo 4400 m/alt. Winter climbing can be a nice adventure in 2 or 3 days. To climb this peak in winter you should climb another peak which name is Sarakchal in Shemshak village. My phone number is 09121757451. I'm from Iran and can lead you more.
