FAQs about flying to Kathmandu
Kathmandu climate
Kathmandu has four seasons. Spring runs March to May and temperatures are between 16 and 23 degrees. Summer is June through August and this is also monsoon season. The temperature range is 23 to 25 degrees. Autumn – September to November – is about as warm as spring; the range of temperatures is 15-24 degrees. Winter (December-February) temperatures range from 9 to 12 degrees. Rain falls outside of the monsoon season.
Getting around Kathmandu
Walking is the best way to see Kathmandu. There are also tuk-tuks, buses and taxis. Renting a car and driver is an option if you are hoping to see a bit of the Valley outside Kathmandu.
Getting from the airport to the city
Tribhuvan International Airport is located in the Kathmandu Valley, some 5.5 km from the city. The airport is served by metered taxis which you can book and pay for in advance.
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. Not surprisingly, it’s a busy spot. Despite the presence of funeral pyres – you may catch a funeral while you are there – it’s a joyful place of musicians, monkeys, beggars, souvenir sellers and dreadlocked and made-up “holy men”.
- 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. It’s a calm space amid the sprawl of the city with neo-classical pavilions, a lotus pond and lush trees and plants.
