Trail Ridge Road is the highest continuous paved highway in the United States, climbing to 12,183 feet as it traverses Rocky Mountain National Park from Estes Park to Grand Lake. Stretching 48 miles through open tundra above tree line, it offers a rare opportunity to experience true alpine wilderness from the seat of a car.
Along the route, the landscape shifts dramatically — from lodgepole pine forests to subalpine meadows to a vast expanse of treeless tundra where the ground is carpeted in tiny arctic plants that take decades to grow. Elk, bighorn sheep, and marmots are frequently spotted roadside.
Several pull-offs invite short walks onto the tundra, and the Alpine Visitor Center at 11,796 feet is one of the highest visitor centers in the National Park system, with exhibits on tundra ecology and a remarkable deck overlooking the Never Summer Mountains.
