Rocky Mountain National Park was established on January 26, 1915, when President Woodrow Wilson signed the Rocky Mountain National Park Act.  Conservation efforts previously spread headed by Theodore Roosevelt, Gifford Pinchot, and John Muir, who all had a deep appreciation for nature, led to the formation of this park.  In the 1930’s Trail Ridge Road was constructed by the American Conservation Corps, to replace the rugged Old Fall River Road, which still exists today as a seasonal, gravel, one way road to the Alpine Visitors Center at 12,000 feet.  Trail Ridge Road, the highest paved road in North America, is open year round.  However, much of it is closed due to deep snow from November to May.

“In years to come when I am asleep beneath the pines, thousands of families will find rest and hope in this park.” – Enos Mills

Watch the Weather

The weather can be extreme in Rocky Mountain National Park.  The town can be 85 degrees and delightful in August.  Yet a drive to the top of Trail Ridge Road, and you can find snow!  Early summer afternoons can bring thunder and lightening storm.  To get below tree line before the storms roll in, start your long hikes in the early morning.

Hydration is the Name of the Game

Our weather here in Colorado is dry.  And at a high altitude, the sun is stronger than you realize.  So make sure you drink LOTS of water.  The rule of thumb is to drink an ounce per pound you weigh. Staying hydrated also helps prevent altitude sickness.
