Getting here: There are flights from Amsterdam and Aruba via Trinidad and Tobago. Not surprisingly most of the tourists here are from the Netherlands. You can also go overland by minibus or shared taxi to Guyana or French Guiana.
The ferry from Guyana to Suriname only runs once a day, supposedly at 11AM and was $10. From Suriname to French Guiana, there are 2-3 ferries a day but you can take a motorized canoe across at any time, just make sure to get your passport stamped on both sides when doing this.
