At 265,000 acres, Rocky Mountain National Park isn't the country's largest national park, nor is it the most-frequented with about 4 million annual visitors (compared to Great Smoky Mountains National Park's more than 11 million visitors). But there is something definitively magical about RMNP, which rises 12,183 feet into the Colorado sky. The main attraction is hiking its 350-some miles of trails that wind through pine and spruce forests, glittering alpine lakes, swaths of wildflowers and if you're lucky, some elk or bighorn sheep. And maybe it's the thinner atmosphere that goes to visitors' heads, but even the most jaded report feelings of awe and wonder after a day or two of breathing in that refreshing mountain air.
Rocky Mountain National Park encompasses 265,461 acres (414.78 sq mi; 1,074.28 km2) of federal land,[1] with an additional 253,059 acres (395.40 sq mi; 1,024.09 km2) of U.S. Forest Service wilderness adjoining the park boundaries.[24] The Continental Divide runs generally north–south through the center of the park,[25] with rivers and streams on the western side of the divide flowing toward the Pacific Ocean while those on the eastern side flow toward the Atlantic.[26]
