Road Conditions: In Nepal, vehicles are driven on the left-hand side of the road. Travel via road in areas outside the Kathmandu Valley remains dangerous. In general, roads in Nepal are in poor condition and lack basic safety features, resulting in significant numbers of accidents and fatalities. Deaths from motorcycle accidents have risen dramatically in recent years and U.S. citizens should consider avoiding riding motorcycles in Nepal, particularly on highways. It is dangerous to travel on the roof of buses as live electrical and other communications wires hang low in many places. Traffic police also impose fines and detain individuals for riding on the roof of buses. Long-distance buses often drive recklessly and bus accidents involving multiple fatalities are not uncommon.

Transportation: Visitors throughout Nepal, including in Kathmandu, are encouraged to use metered taxis and avoid public buses and micro buses. Many taxi drivers will refuse to use the meter, insisting on negotiating the price instead. In addition, there have been instances of taxi drivers tampering with the meters in an attempt to charge higher than normal fares. If you believe that you are being overcharged, you may wish to file a complaint with the traffic police on the street or at the nearest local police station.

Adventurous gastronomes should venture into the markets to sample fresh fruits including umpteen varieties of bananas, which are some of the sweetest you will ever taste.

At the higher end of the market, Kathmandu has developed an international culinary scene where diners can find dishes from all over the world. Chefs artistically prepare five-star menus, and food competitions have aimed to encourage budding restaurateurs.
