Along Trail Ridge Road, stop at the Rainbow Curve viewing area to appreciate a varied and spectacular view.

Rainbow curve rests on tree line, marking the moment of passing between alpine and sub-alpine ecosystems. From this vantage point, visitors can view Horseshoe Park, Deer Mountain, the Alluvial Fan and the Mummy Mountain range. Rainbows can often be seen here after a rain, giving the location its name.

Note: Trail Ridge Road closes mid-October to Memorial Day. Extreme weather can change the status of Trail Ridge Road at any time—be ready to adjust your travel plans if needed, and always check the weather before you start your drive.

Altitude Warning: Altitude sickness affects many visitors every year. Symptoms include headache, nausea, fatigue, dizziness, vomiting, and even unconsciousness. Altitude can also aggravate pre-existing conditions like heart and lung disease. Take your time, drink water, eat, and rest. The only cure for altitude sickness is to go down to a lower altitude.

Help keep wildlife wild. Please do not feed any wildlife (chipmunks, squirrels, birds) that frequent this area. Never approach wildlife. Animals that learn people are a source of food can become aggressive or stop hunting or foraging on their own. Keep your distance - it's the law! You could be hurt or issued a fine.
