If your doctor says you need malarials to travel to Cambodia, get a second opinion. Malaria is generally restricted to the rural areas of the country, well outside Phnom Penh, Sihanoukville and Siem Reap. If you're planning on spending long periods of time in remote areas of Rattanakiri or Mondulkiri, this is a different matter. Regardless of where you are going, exercise care and common sense, and you'll minimise the chances of catching it (and dengue fever) without purchasing expensive medicines and enduring their dangerous side-effects. Women of a slight build should not, under any circumstances, take Lariam.

Malaria is transmitted by mosquitoes. Plasmodium falciparum infection is the most serious and can be fatal. Some types of malaria may persist for forty years after infection. Symptoms develop 10-14 days after being bitten and consist of high fever with alternate shivering and sweating, intense headaches, and usually nausea and vomiting. Seek prompt medical attention if you develop these symptoms. Anti-malarials are not 100% effective, so do not assume you cannot have malaria just because you are taking them.

You can, but not legally. People will frequently smoke grass in some guesthouses and restaurants, though being discreet is a very good idea as Cambodian jails are not much fun. Other drugs are available, though none are legal.

If you do try to tempt fate, be aware that although drugs are generally cheaper than in the west, quality and dosage vary tremendously. Methamphetamines are often passed off as ecstasy, speed and all types of other trash is passed off as cocaine, and so on. Overdoses are not uncommon.

Most travellers shall be issued entry-visa upon their arrival.  For further information, please directly contact the Immigration Police Unit at the Phnom Penh Airport International or the Siem Reap Airport. Some countries where the Royal Embassies and Consulates of Cambodia installed, travellers shall then apply for an entry-visa prior to their departure. Multi-entry visa can be extended at the Department of Foreigner of the Ministry of Interior.
E-visa is available now and tourists can apply through online http://evisa.mfaic.gov.kh/index.php?version=eng

Be ensured that the Cambodian railway network is under development and time consuming to catch train.

By road, Cambodia now has several bus companies and private taxis are also available throughout Cambodia. But the bus operations are still very limited based on the road condition. Travellers can take coach from Phnom Penh to neighbouring provinces such as Siem Reap,  Kampong Speu, Takeo, Kampot, Kampong Chhnang, Kampong Cham, Neak Leung (in Prey Veng), Ta Mao (in Kandal) and to two other cities of Sihanouk Ville and Kep. In particular, Phnom Penh to Ho Chi Minh City along the National Road 1 is now available. Taxies are available to make a journey throughout the country.

Cambodia is 7 (GMT+7) hours ahead of Greenwich Mean Time (GMT) and 12 hours ahead of the United States in Boston, Pacific Time Standard.

Cambodia has a tropical climate with three distinct seasons – Hot/Dry from March to May, Rainy/Monsoon from June to October and small Winter/Cool from November through February. The average annual temperature is 28 C – 32C, this ranges in the capital city of Phnom Penh. The temperature during the small winter is 14C - 16C at provinces throughout the country but in Phnom Penh is about 16C – 20C. In the early April, it is found that there are some rain showers through the beginning of May. The end of May and the beginning of June the full monsoon starts till the end of October.

As Cambodia's climate is hot and humid almost all year round, it is ideal to have light clothing to be worn throughout the year. But during the small winter from December till March, you are advised to wear thick clothing. It is also advisable for ladies and gentlemen, when entering any Buddhist pagoda, in tradition, ladies are inappropriately found to wear shorts, trousers or any sexy attire. Men and women are cultured for a dignitary image¾is not to wear shorts and cap when you are in the complex of a Buddhist pagoda. The flip-flops, boots or shoes must specially be taken off before entering into any Buddhist temple. At ancient temples, you are free to wear any as you wish but not bras and under-pan.

Not generally, but most top-range hotels, some middle range and very few lower range hotels will accept them. There are many restaurants and bars accept them. Most travel agents prefer cash. If you can use them, expect to be charged a 3% surcharge.

The ANZ Royal Group has finally brought international access, 7-day, 24-hour ATMs to Cambodia. ATMs can be found in all the main tourist centres across Cambodia (or at least Phnom Penh, Siem Reap, Battambang and Sihanoukville).

Most people now rely on a mix of cash, credit and debit cards and travellers cheques. Cambodia has ATMs of any use to foreigners on every corner in Siem Reap, Phnom Penh, Sihanoukville Battambang. For cash, bring US dollars because it is accepted everywhere.

Generally speaking, yes, with the biggest problems being traffic accidents. Using common sense means you'll probably get out of Cambodia in one piece. Violent crime against foreigners occasionally takes place, but overall it's fairly safe.

Yes. One of the best or worst things (depending on your viewpoint) is how easy it is to meet other travellers while exploring Cambodia. If you're travelling by yourself, chances are you'll meet loads of people than if you're with a partner, and when you come to leave the country you'll realise you've developed a collection of friends from all over the globe. It's rare indeed for a lone traveller to not hook up with others for at least a part of their trip. When this is combined with the very gregarious nature of Khmers, it's actually pretty difficult to stay alone for long periods.

As with just about anywhere in the world, you are safer travelling with others, but as long as you use your common sense, travelling alone is generally perfectly safe. Take all the usual precautions: carry copies of all your documentation in case you are stolen and try to keep in touch with family or friends overseas. There's no shortage of internet cafes across the country, so there's no excuse for not occasionally dropping an email to placate worriers at home. Better still, send a postcard - some people still use them.

If you ever find yourself in an uncomfortable situation, don't hesitate to ask a local for assistance - by and large Khmers are very helpful, end even if they don't speak your language, they'll be able to help you find someone who does.

Cambodia is not world-renowned for its vegetarian food, nor for its food in general for that matter. Phnom Penh, Siem Reap has a limited range of vegetarian places, but other than that you're in for a lot of veggie stir-fries. Ot n'yum Satch means you don't eat meat. Even French places tend to not cater very well to vegetarians.
