The Berbice River meets the Atlantic at New Amsterdam, making the town both a port and the natural crossing point for travellers heading east along the coast toward Suriname. The river is broad and brown — coloured by tannins from the forest upstream — and the ferry crossing from Rosignol on the west bank to New Amsterdam is a reliable element of the journey east from Georgetown.
The riverfront at New Amsterdam has some basic stalls and a view over the wide water toward the Atlantic. Crab Island sits in the river mouth and can be reached by local fishing boat — it's used mainly by local fishermen and has no facilities, but the estuary birdlife is good. Upstream, the Berbice River runs deep into the rainforest interior; river tours can be arranged from Georgetown or Linden.
