Think you need pine trees for an exciting Colorado hike? Well, no, you don’t. So, instead, take a trail on our beautiful mountain passes for an exhilarating day! Twenty trails that I loved and can’t wait to share. Not all are at the summit, but all are phenomenal!

All the hikes are not on 4WD mountain passes; each one is easily accessible by car.

If weather conditions are favorable and you’ve acclimated to high altitude, wander and see Colorado at its highest! I stress being acclimated to the altitude because it is real and can make you sick. Read here for more info  >High Altitude Effects and Advice

Know the weather forecast – before hiking above treeline – a good source is to search >
