One of the most unique environments in the world survives on Costa Rica’s mountaintops-at least for the moment. Cloud forests like Monteverde’s are formed by a combination of wind and geography (individual cloud forest descriptions are listed in the menu to the left).
When tradewinds flow from the northeast across the warm Caribbean Sea they drive moist air into the Cordillera Tilarán. The slope of the mountains pushes the air upwards to cooler elevations around Montevede. Since cool air holds less moisture the excess humidity forms tiny droplets, mist and clouds.
