Air and river transport are the only ways to penetrate the interior, due to the lack of roads.
Rivers offer scenic routes to parts of the interior that are otherwise inaccessible. There are few scheduled services, and prices are negotiable. Your best bet is to arrange something ahead of time in Paramaribo. Ferries and launches cross some major rivers, such as the Suriname and the Coppename, and are very cheap.
Suriname’s roads are limited and navigating them can be dicey. Passenger cars can handle the roads along the coast and to Brownsberg, but tracks into the interior are for 4WDs only. Rental cars are available but expensive and you can’t take them over borders. Driving is on the left (a legacy of the British). An International Driving Permit is required.
Midsized buses (referred to locally as ‘jumbos’) on the coastal highway are frequent and cheap. Arrange your fee with the driver before you get on. Government buses cost less than private buses but may be more crowded. There are very few buses off the main routes.
Shared taxis cover routes along the coast. Though several times more expensive than buses, they are markedly faster. Cab fares are negotiable and generally reasonable; set a price before getting in.
Small planes, operated by Surinam Airways (SLM; www.slm.firm.sr) and Gum Air (www.gumair.com), which is mostly a charter airline, shuttle people between Paramaribo and remote destinations, including some nature reserves.
