Trail Ridge is a high mountain pass at an elevation of 3.719m (12,201ft) above the sea level, located in the Rocky Mountain National Park in the north-central region of the U.S. state of Colorado, in USA. The pass is traversed by the Trail Ridge Road, the highest continuous paved road in the country.
The road, also known as Trail Ridge Road/Beaver Meadow National Scenic Byway, cuts through Rocky Mountain National Park between the towns of Estes Park and Grand Lake, and is one of the best ways to see the Continental Divide as it cuts through Colorado. The name "Trail Ridge Road" derives from it proximity to historic pathways used by native peoples to cross the Rocky Mountains. It's one of the highest mountain roads of Colorado.
Located in Larimer County, the drive is definitely worth it. Don’t forget your camera! It traverses Rocky Mountain National Park from Estes Park, Colorado in the east to Grand Lake, Colorado in the west. Construction began in 1929 and was completed to Fall River Pass by July 1932, with a maximum grade of 7%.
Avalanches and heavy snowfalls can sometimes block some sections of the road and can be extremely dangerous due to frequent patches of ice. Trail Ridge Road is closed during the winter, and often remains closed until late spring or early summer depending on the snowpack. It requires access to Rocky Mountain National Park even for local residents.
