Kaw-Roura Marshes National Nature Reserve, National nature reserve in Régina and Roura, French Guiana

The Kaw-Roura Marshes National Nature Reserve covers 94,700 hectares between the Mahury River to the north-west and the Approuague to the east, from Roura to Régina. Its core is a floating savanna of Cyperus sedges and Araceae, fed by the Kaw River and Angélique Creek, with mangrove, flooded savanna, marshy forest and tropical rainforest around it. The village of Kaw lies inside the reserve, and the whole area is reached only by boat.

The area gained recognition as an internationally important Ramsar site in 1993 and received its protected status in 1998. This designation stemmed from its role as a critical habitat for migratory birds and other wildlife species.

Kaw is a small inhabited village inside the reserve, the only settlement within its boundaries, and the starting point for boat trips into the marshes. The reserve is nicknamed "the Everglades of Guiana". Access is by boat from Kaw, along the Kaw River and Angélique Creek, where black caiman, hoatzin and red ibis are sought by visitors.

Access to the reserve requires traveling by boat from Kaw village, with the approach involving lengthy forest roads from the main city. Visitors should prepare for wet conditions and bring suitable gear for extended water travel.

The reserve holds 535 bird species, 74% of French Guiana's avifauna, and serves as a sanctuary for the black caiman, one of four caiman species recorded there. Its floating savanna of Cyperus sedges and Araceae is fed by the Angélique Creek and the Kaw River.
