Nagarkot is a great venue for mountain biking where international mountain biking competition has been held.
If you have an adventurous spirit and want to experience Nepal in a unique way, Himalayan mountain bike can be the best for you. The biking trail from Nagarkot to Sankhu is downhill and is around 11.5 kms descent. With a progessive drop in altitude of 515 metres to sankhu, the bumpy road descends before a fantastic Himalayan backdrop and typical Nepali Countryside that will make every bit of the event memorable. The road is rough and there are lots of switchbacks that will require cautious riding. You will have to perform some manoeuvres while biking.
Around Nagarkot
From Nagarkot the options before you are almost unlimited. Rough roads and trails radiate in all directions: northwest to Sankhu; southwest to Changu Narayan; south to Nala and Banepa; east to Hiuwapati, Sipaghat and Panchkhal; and north to Chisopani and the Helambu trails. However, there are endless forks, many of which lead to dead ends or treacherous descents, so don’t bike alone.
Unless you’re a very strong rider, the ascent to Nagarkot will probably be all you care to do in a day, and in any case you’ll want to spend the night for the views the next morning. Most bike tour operators run popular two-day trips, including transportation up, an overnight stay, and the amazing descent back to the Kathmandu Valley, taking more pleasant back roads.
