Cambodia is a beautiful country, with warm, kind people, and it's building itself up. There is still much work to be done. If you decided that you want to help, volunteer or teach, there are few ways to do it:

1) Just arrive in Cambodia
Buy a flight ticket and get the proper vaccinations. You can get a Visa on arrival. Come to Phnom Penh, Siam Reap, Sihanoukville or Battambang in Cambodia and find a guesthouse to your liking. When you've settled in and chilled out for a bit, just have a look around town and quite easily find a place to volunteer.
 

2) Email before you get here:
If you want to assure your place in advance you can apply by mail one of the organizations you will find in our directory, or in the Cambodia Yellow Pages.

or 3) Apply for an organization that will arrange everything for you from your country: a flight, pickup from the airport to an arranged residence in Cambodia, and a place for you to volunteer in.
