Climbed Longs Peak in Rocky Mountain National Park. It is a long, serious day and I think a lot of people underestimate it because it is a walk-up on paper. What matters: - Start absurdly early. Alpine start, headlamp for hours, and be heading down before the weather builds. - The route past the Keyhole is exposed scrambling. If heights bother you, you will know quickly. - Altitude is the real filter. Acclimatize first if you came from sea level. - Turn around when the clouds build. The mountain will be there next year. Rocky Mountain backpacking around it is excellent too — I paired it with a couple of nights in the backcountry, which made the summit day far more pleasant. Anyone done the Loft or Clark's Arrow variation? Curious how it compares.
