Diamante Eco Park doesn't do things by half. Not only is it Guanacaste's largest animal sanctuary, it's also home to Costa Rica's longest zipline, too. Hit the heights on a thrilling 15-platform zipline course that sees you whizz along cables slung between canyons and take on a 1,360m-long Superman-style flight across tropical valleys and views over the Gulf of Papagayo.
