Special Regulations & Warnings
Rocky Mountain National Park's high elevation and extremes of climate and terrain are among its most appealing features, but also its greatest hazards. Hikers should try to give themselves several days to acclimate to the altitude before hitting the trails that climb above timberline, and hikers with respiratory or heart problems would do well to discuss their plans with their physicians before leaving home. Hikers need to be prepared for rapidly changing conditions, including sudden afternoon thunderstorms in July and August. If lightning threatens, stay clear of ridges and other high points.
