What is good to know if travelling to Kathmandu?

  • The temple of Changu Narayan is said to be the most ancient temple in the Kathmandu Valley, dating back to the 4th century. It is one of the seven Unesco World Heritage Sites in the valley. 
  • Thamel is where lots of travellers head. There are restaurants, hotels and shops all catering to international visitors. Jochhen Tole is probably better known as Freak Street, the original magnet for the hippies. It’s a popular alternative to Thamel, but its freakery is long past. 
  • Jazzmandu is the jazz festival that takes place each autumn. It’s the only jazz festival in the region and is internationally renowned. 
  • Pashupathi, one of the most important religious sites in Asia, is dedicated to Shiva, the God of destruction. Every Hindu in Nepal should visit during their lifetime.

  • The Garden of Dreams in Kaiser Mahal, in front of the Western Gate of the Narayan Hiti Royal Palace, was the creation of an Austrian Field Marshal in the 1920s. It lay neglected for many years, but has been brought back to life – with funding from the Austrian Government – since the mid-2000s.
