On Costa Rica's Osa Peninsula, howler monkeys rule the rain forest and locals still pan for gold. Andrew McCarthy explores the region's wild side.
[MUSIC] Tiny Costa Rica in the heart of Central America has long been known as an outdoor adventurous playground. Cloud forest, active volcanoes, miles of surf on both the Caribbean and the Pacific. What most folks don't know is that this wild country has an even wilder backyard, the Osa Peninsula. [MUSIC] I'm Andrew McCarthy, let's go see it. The Osa juts out into the Pacific just north of Panama. Seven hours down this trail promises the relief of ocean breezes As recently as the 1980s, the Oso was prime gold mining terrain and you can still find a few die-hard dreamers, looking to strike it rich. [MUSIC] Lying at the heart of the Oso is the [FOREIGN]. It's been dubbed the most ecologically intense place on Earth. [SOUND] That's a boa constrictor. [MUSIC] [SOUND] Now that's a tree. [MUSIC] [SOUND]. Oblige you. In the river we're crossing, waist deep; the river's getting high [SOUND] [MUSIC]. [MUSIC] This country boasts 800 miles of beaches. We finally found one. [MUSIC] At last. One of the many pleasure of Costa Rica is that after a long, hot day on the trail you can always find a soft place to lay your head. Agh.
