Here, you can enjoy stunning views of Rabbit Ears. It's a great place to pause and take in the views before making your way back.

For mountain bikers, the Rabbit Ears Trail is a lung-scorching climb and a heart-pumping descent! This technically easy jeep road delivers postcard-worthy panoramas, but thin air and steep sections test your endurance.

Built in 1905 and at an elevation of 11,600 feet, this is the remnants of the old train trestle that connected Denver to Winter Park. The tracks were removed in 1938 and the bridge was used for automobile traffic until 1955. These days it can only be accessed by hiking or biking.

This is a classic Fraser singletrack trail with some fun features. Get ready for banked turns and some jumps, but keep your eyes open for obstacles and roots in some sections.

Tabernash is a small highway-side community nestled between the towns of Granby and Winter Park in the valley of the Fraser River. The biggest draw is nearby Arapaho National Forest and Rocky Mountain National Park, which offer year round outdoor recreation.
