Reserva de Biosfera Bosawás
The North Atlantic Autonomous Region (RAAN) province of Nicaragua is fertile ground for exploration. The region's great jewel is the Reserva de Biosfera Bosawás, the largest protected expanse of rainforest north of the Amazon. At 20,000 sq km (7,722 sq mi), it's almost 15% of Nicaragua's national territory. Access is tough, and travel is most easily done by river.
