When I first started my peak-bagging journey, I was obsessed with climbing 14ers. Living in California gave me some great options, but nowhere near the variety Colorado offers. The flipside? Not as many people in California are chasing those 14,000-foot summits. In Colorado, the peaks are buzzing with climbers.
After my first few successful summits in California, I felt invincible. I tackled these mountains car-to-car and stuck to routes no harder than Class 4. Climbing solo felt completely fine—until the day I experienced altitude sickness.
