This nature reserve has an area of 78,170 ha and is situated along the Coppename River. It can be reached by airplane (less than an hour) or by car (120 miles) to be followed by a 3-4 hour boat ride. The reserve headquaters and the tourist lodges are located on Fungo Island in the middle of the Coppename River.

Raleighvallen (Raleigh Falls) is the name for the extensive set of rapids near Fungo Island in the upper Coppename River.

The reserve is internationally known as a bird and monkey paradise. You'll see toucans, macaws and parrots and 400 other species. Hanging from the tree branches on and around Fungo Island you'll notice the pendulum-shaped nests of the weaver birds (oropendulas) which are large, colonial nesting birds with yellow outer feathers. These nests can be close to a meter long.

Another interesting feature is the Voltzberg. This granite sugarloaf mountain can be reached on foot in about three hours by jungle trail from Foengoe Island. The Voltzberg rises about 150 m (375 ft) above the forest canopy. The night can be spent in a hammock in a sinple jungle camp at the base of the mountain. During the night you will be surrounded by the sounds of monkeys, tree frogs, and other creatures from the tropical rainforest.

The reserve is also the home of the spectacular and rare cock-of-the-rock (Rupicola rupicola).

There is the possibility, as well, of encountering deer, tortoises, tinamous, and several species of monkey on the 7 km (one-way) hike to the mountain. The trail is good but the damp climate of the rainforest, and the steep climb up the Volzberg, make it a heavy trip, especially for the out-of-shape hiker.
