Most tourists visit Suriname for the biodiversity of the Amazonian rain forests in the south of the country, which are noted for their flora and fauna. The Central Suriname Nature Reserve is the biggest and one of the most popular reserves, along with the Brownsberg Nature Park which overlooks the Brokopondo Reservoir,  one of the largest man-made lakes in the world. In 2008, the Berg en Dal Eco & Cultural Resort opened in Brokopondo. Tonka Island in the reservoir is home to a rustic eco-tourism project run by the Saramaccaner Maroons. Pangi wraps and bowls made of calabashes are the two main products manufactured for tourists. The Maroons have learned that colorful and ornate pangis are popular with tourists. Other popular decorative souvenirs are hand-carved purple-hardwood made into bowls, plates, canes, wooden boxes, and wall decors.
