Paddles slice through churning waters, keeping rafts on their course down Clear Creek as it cuts through the Denver Mountain Parks . At the base of the red crags of Gore Canyon, the white-capped water of the Colorado River foretells rafters’ trips through daunting class IV and V rapids. Elsewhere, guests make like protoplasmic coat hangers as they zipline over the scenery of Idaho Springs.
But rafting trips and zipline tours are just the beginning. Arkansas Valley Adventures leads all kinds of expeditions through Colorado’s mountains and valleys, tossing in ATVs, hot air balloons, helicopters, horses, and fishing rods with the paddles and ziplines. While flying down the Eagle River explorers will have plenty of chances to get in touch with their rugged side and ask ancient rock faces whether the paleo diet is an apt reflection of the habits of early humans.
