1. Alderfer / Three Sisters Park

EVERGREEN.   The opportunity for hiking and mountain biking that's most convenient to Denver is Alderfer / Three Sisters Park in Jefferson County. It's known for magnificent views of the Three Sisters and Big Brother peaks, and its Summit trail presents views of the Continental Divide. If elevation is what you're looking for, Sisters trail offers a challenge for bikers, escalating 946 feet and promising plenty of physical exertion.   (© 10Best)
