When to go

Elevations in the park range from approximately 875 feet (267 meters) to 6,643 feet (2,025 meters) and the topography can drastically affect local weather. Temperatures can vary by 10-20 degrees Fahrenheit from mountain base to top, and clear skies lower down do not guarantee equally pleasant weather at higher elevations.
