Obo National Park (Portuguese: Parque Natural Ôbo de São Tomé e Príncipe) is a national park of São Tomé and Príncipe, covering some 235 km² (30% of the island) of São Tomé Island in its south and 65 km² of Príncipe Island. The national park is known internationally amongst conservationists for its biologically rich dense virgin rainforests. It is also characterized by a wide range of biotopes, from lowland and mountain forests, to mangroves and savanna area, which contribute to its unique ecosystem. The park includes virgin Atlantic high altitude rainforest and secondary rainforest (known to locals as capoeira) which contains abandoned plantations.[1]
