At present there are domestic flights from Phnom Penh to the major provincial capitals. Air travel to Siem Reap to view the Angkor Temple complex by air is recommended over other transport options, although travel by boat is possible.
There are some domestic airlines:
Cambodia Angkor Air
Cambodia Bayon Airlines
Sky Angkor Airlines
Phnom Penh International Airport
Siem Reap International Airport
Sihanoukville International Airport
International airlines have directly flights to and from Cambodia including:
Taxis can be booked by phone and are increasingly reliable. They are also available at the larger hotels. Meters are usually not used and drivers prefer a fixed rate. For longer trips out of town, however, taxis can be rented for a full or half day at negotiable rates.
There is no public transport system operating in Phnom Penh. The main mode of transport for the local population and some expatriates is by man-powered 'cyclo' taxis or by motorbike taxis and prices are usually negotiated in advance. For security and safety reasons you should not use cyclos and motorbikes at night. Accidents are frequent and personal injury rates quite high.
Travelling by train, bus, taxi, boat, helicopter and aircraft outside of Phnom Penh have varying degrees of risk attached. The train services from Phnom Penh to Battambang and to Kampot have in the past been attacked by bandits.
Phnom Penh has a growing range of restaurants of Western standard which are suitable and/or safe to dine at. Local versions of Malaysian, Thai, Japanese, French, Chinese, Italian and European food are represented at varying standards and prices. Vegetarians are not usually catered for in most restaurants and you may have to request a meal without meat, chicken or fish. BYO is accepted in most restaurants, usually with no charge, but it is best to ascertain in advance as some larger hotels and Western restaurants levy expensive corkage charges. English is spoken in all the international restaurants, but to a limited extent in the local Cambodian restaurants.
Bills are usually paid in US dollars though most down-market restaurants or eateries will accept riel. Credit cards are accepted only in the larger hotels.
Usually, tips in Phnom Penh amount to five per cent of the bill in restaurants and cocktail lounges. However, most of the larger establishments have a service charge to cover the tip. Nothing else is necessary but small 'riel' change is usually left. There is usually an added charge of 10 per cent government tax as well. When there is no monetary amount on which to base a tip, the amount is determined according to one’s assessment of the worth of the service.
