2. Choco Rainforest, Colombia/Ecuador
What makes this rainforest so intriguing is the lack of research that has been done here. Wetter than the Amazon but largely unexplored, the Choco Rainforest is home to flora and fauna that exist nowhere else on the planet, such as the Colombian black spider monkey. Hidden waterfalls, dense mangroves, lush vegetation and unique wildlife are what visitors can expect to find here. Rare poisonous frogs and endangered bird species call this forest home. This rainforest is being subjected to large scale deforestation, and conservationists are doing their best to save it before it disappears forever.
