Overview
The beautiful 170km-long Rio San Juan marks the border with Costa Rica and runs from Lake Nicaragua to the Caribbean Sea. Strategically important, it has a hectic history of disputes and attacks from outside Nicaragua and within. The remarkable fortress at El Castillo, built by the Spanish to repel pirates (although Horatio Nelson briefly held it after capture by stealth), bears witness to that. However it’s now a peaceful waterway passing through thick tropical jungle, where efforts are being made to encourage eco-tourism. Downstream from El Castillo is the primary rainforest of the Reserva Biológica Indio Maíiz, possibly the largest nature reserve in Central America.
