Characteristic of this area is the dramatic contrast in
topography. Mountain ranges, volcanoes, lakes, rivers and fertile
plains support numerous varieties of bird and wildlife, each
offering different types of activities. The two Cordilleras, or
mountain ranges, are very different from each other. The Cordillera
Tilarán has rolling mountains that used to be covered in cloud
forests; those remaining are protected reserves of which the
Monteverde Cloud Forest Biological Reserve is the most popular with
visitors, offering nature trails, horse riding and canopy tours.
The Cordillera de Guanacaste is an impressive string of volcanoes,
some protected within national parks. Between the ranges are Lake
Arenal and the nearby active Arenal Volcano and surrounding hot
springs. Further north, in the tropical humidity of the lowland
plains, lies the remote wildlife refuge of Caño Negro, a vast
wetlands area that is one of the best places in the Americas to see
river wildlife, including numerous birds, mammals and reptiles. The
fertile plains are dotted with a mixture of agricultural fields,
cattle ranches and expanses of protected areas serviced by a maze
of streams and rivers.
