Milner Pass

Milner Pass is a mountain passage through Rocky Mountain National Park located at approximately 10,759 feet. The route forms part of Trail Ridge Road, a drivable connection that runs through the park's northern region.

A surveyor named T.J. Milner explored this area in the 19th century and determined the terrain could not support railroad construction. The route was later developed as a road connection across the Continental Divide after the rail project was abandoned.

The pass links two mountain communities and forms part of one of North America's highest paved routes. Visitors experience the journey across the Continental Divide through alpine terrain that separates two different watersheds.

The passage is typically accessible by vehicle from late May through October and requires a park entrance permit. Bad weather or snowfall can close the road unexpectedly, so visitors should check road conditions before traveling.

At the eastern edge of the pass sits Poudre Lake, where Cache la Poudre River begins its journey. This river flows eastward toward the plains, showing how the pass separates two different water systems.
