Today we're taking a walk through the clouds to visit one of the most beautiful and biodiverse places on the planet. Costa Rica's Monteverde Cloud Forest Reserve is in the Tilarán mountain range 5,000 feet above sea level. Hundreds of animal species and thousands of insect and plant species call the forest home. Diligent nature lovers could count nearly 700 types of butterflies and 500 species of orchids during a visit. Famous in the scientific community, the forest also attracts more than 70,000 tourists a year.
