Micro Bus has become very popular lately. They are 10-12 seater with very fast service. It has almost replaced local bus service given its fast service. However, apart from previous few routes, Micro Bus has come up with many other alternate routes and now has got good coverage. The fare is more expensive than the local bus.
Super Express Bus
Super Express Bus - or 'Supper Express' as the ticket says is somewhere between a micro and a local bus. These generally depart between 5 - 7AM and do not stop to pick up locals along the way. People are not allowed to sit on the roof. The 'supper express' is more expensive than a local bus but cheaper, (and faster) than the micro.
Although the system can be confusing they are cheap. They can be crowded at times both with people and domestic animals such as goats, ducks etc. Some buses will not depart until full to a certain quota.
Book a few days ahead at a Kathmandu or Pokhara travel agent (or your hotel will book for you). A few steps above local buses (no goats, everyone gets a seat) but not much safer. "Greenline" is the most reliable company and has trips between Kathmndu, Chitwan, Lumbini and Pokhara.
Good for short jaunts if you don't have much luggage and don't mind being bounced around a bit. Bargain before you get in, and don't be afraid to walk away and try another.
These come in two types. One is a three wheeled electric or propane powered micro-bus for 10-13 passengers. They run in different routes around the city and cost 5-12 NRs. The other type is a newer Toyota van running the same routes at a higher price and a bit faster and safer. Be prepared for a crowd.
There are two types of taxi -- "private", which pretty much run from the airport to your (upscale) hotel; and "10 Rupee", which don't leave until they are full. When haggling for fare remember that Taxi drivers have been hit hard by the petrol crisis sometimes queing up overnight to get 5 litres of petrol at twice the market price. So be sympathetic but don’t get ripped off! Offer to pay 'meter plus tip', 10% is more than enough.
Custom or classic motorcycle
Run by a European couple, Hearts and Tears in Pokhara offer lessons, guided tours and rental of 350cc and 500cc Royal Enfield bikes. In Kathmandu, Himalayan Enfields (behind the Israeli Embassy on Lazimpat)sells/rents good bikes and does repairs. The official Enfield dealer in Nepal is in Balaju Industrial Estate off the Ring Road.
Another choice is to rent a small motorcycle. And it can be rented in the Thamel area. Again with the petrol crisis, motorcycle rental has become a costly choice, depending on availabily 1 litre of petrol will cost you 105-125 NRs on top of the rental fee (300-800NRs).
Although motor roads are penetrating further into the hinterlands, many destinations can only be reached by foot (or helicopter). See the section on trekking, below.
