An airport tax for international and domestic flights is included in the airfare.

Begging is not widespread in Cambodia and visitors are requested not to encourage development of this practice by giving money or sweets to children. Think twice before buying anything from children on the street, beaches or at temples and refrain from giving money to begging children or parents with infants. It keeps them on the street and places them at risk. If you want to help, don’t give directly to children. Instead find and support local charity organizations that help these children have a better future.

Cambodia can be visited throughout the year. However those planning to travel extensively by road should avoid the last two months of the rainy season when some countryside roads may be impassable.

The climate is tropical and distinguished by three major seasons.

  • Dry Season: November - March
    The most pleasant season is the dry season from November to March during which temperatures are cooler (averaging 20-28⁰C).
  • Hot season: April - May Average temperatures are 30-35⁰C.
  • Rainy season: June - October
    Locally referred to as the "green season" during which temperatures are relatively cool (average 25-30⁰C). At this time of year it rarely rains in the morning. Instead, most precipitation comes in the afternoon and even then it’s only sporadic. Rainfall varies considerably from area to area. Whereas the seaward slopes of the south-west highlands (Kompong Som and Kampot provinces) receive more than 5,000 mm of rain per annum, the central lowlands average only about 1,400 mm.

Since Cambodia has a hot and humid tropical climate, casual and lightweight clothing is a must with clothing made from natural fibres being the best option. A jacket might be needed on cool winter evenings or in hotels and restaurants that use excessive air conditioning.

A hat and high-factor sun block is advisable as protection against the hot sun when sightseeing outdoors and while travelling with on a tour, in addition to comfortable walking shoes.

Although many tourists do wear shorts and sleeveless shirts, please respect the culture and traditions of Cambodia and dress modestly, expecially when visiting temples and religious sites.

The local currency is the riel, however in Phnom Penh and most major tourist destinations, almost all goods and services are calculated and paid for in American currency. The rate of exchange is approximately 4,071 riel to USD 1 (1 June 2016).

Credit cards, traveller’s cheques and currencies other than USD are accepted only at a few places such as major hotels, at some foreigner-owned restaurants and at some souvenir shops. It is best to carry USD in small denominations. ATM machines are offered by ANZ Royal Bank, Cambodian Public Bank, SBC Bank and Canadia Bank. ATMs accept all major credit cards and can be found at various places in Phnom Penh, Siem Reap, Battambang and Sihanoukville.

Regulations are relaxed and simple formalities should be observed when entering the country. Every traveller has to complete a customs declaration form during the arrival flight and must submit it on arrival.

Any amount of foreign currency can be brought into Cambodia, but the amount of Cambodian currency must not exceed 100,000 riel per person. Tourists and non-residents carrying over USD 10,000 in cash or its equivalent must declare so in order to ensure they will be allowed to exit the country with that amount.

A Diethelm Travel representative will meet travellers at the exit of the airport building, after airport immigration and customs control points have been passed. For easy recognition, our representative will display a Diethelm Travel sign with the names of the guests or group. It also will be this representative who will be in possession of tickets for ongoing flights of the clients. Should clients buy international tickets through us, they will receive them on their departure day.

Khmer cuisine is closely related to those in neighbouring Thailand and Laos although it is not as spicy. Curries, stir-fried vegetables, rice, noodles and soups are staples of the Khmer diet. Fresh river fish and shellfish are both abundant and delicious. Western food is provided only in the major cities although other Asian dishes are widely available. Cambodia is well known in the region for its prahok, a strong, fermented fish paste used in a variety of traditional dishes.

Tap water should never be drunk. Bottled mineral water and bottled drinking water are available in all reputable hotels and restaurants. Similarly, salad and fruit served at these establishments are safe.

Pagodas and the temples are sacred, religious places where knees and shoulders have to be covered. Although many tourists do wear shorts and sleeveless shirts, please respect the culture and traditions of Cambodia. This is also the case for the Royal Palace and Silver Pagoda in Phnom Penh. Visitors who do not abide to these rules of conduct may not be allowed access. Shoes (as well as hats) have to be removed before entering pagodas.

After years of political and social upheaval, Cambodia now enjoys relative stability. Continuing efforts are made to reconstruct the country from decades of war, to upgrade the infrastructure (roads, bridges, airports etc) and to ensure security. Cambodia is now once again safe for travel.

However some simple common sense precautions with possessions lessen the chances of becoming a victim to theft. Carry your handbag or rucksack to the front of you and be aware that handbag snatches due to theft from motorbikes occur, especially in the larger cities such as Phnom Penh.

Cambodia's stunning Khmer crafs

Home to an abundance of cultural riches, Cambodia is in many ways ideal for shopping. Between its age-old weaving traditions and high-caliber woodcarving, the country’s level of craftsmanship verges on incomparable. Today, the country is in the midst of a handicrafts revival of sorts: from gemstones and silver, to silk and sarongs, there are plenty of options for the sophisticated traveller in Cambodia.

Original Art
Whether you’re an art lover or big-time collector, Cambodian art is an exciting genre that’s gaining traction in the international market. If you’re looking to find a special piece for your home, stop by one of the many shops to peruse their selection. No doubt you’ll discover a wealth of oil paintings, bronze sculptures and weavings with which to adorn your space.

Shopping Smartly
We suggest proceeding with caution when purchasing jewellery, gold and stones as Cambodia does have its fair share of fakes. Similarly, when buying antiques please be aware that exporting them is subject to the Ministry of Culture’s authorisation. Finally, be sure to bargain at every step of the way to get the best price possible — and don’t forget to enjoy the thrill of the chase!
