The Upper Suriname River has a watershed area of 16,500 square kilometers (it is not clear if this includes the Gran Rio).

[4] Due to its location in the jungle, isolated from the rest of the world, the area has experienced a persistent lag in development, which continues into the early 21st century.

[4] There are airstrips for small planes and helicopters at Laduani, Botopasi, Djumu, and further along the Gran Rio at Kajana.

Medical posts are located upstream in Pokigron, Jawjaw, Laduani, Goejaba, Debikè, Kambaloea, Heikoenoenoe, Semoisi, Djoemoe, and along the Gran Rio in Cajana.

The main activities include relaxation, jungle hiking, wildlife spotting, swimming, fishing, visiting villages, interacting with the local population, and experiencing a different culture.
