Quick Answers

What is a 14er?

A "fourteener" or "14er" is a mountain peak with an elevation of at least 14,000 feet (4,267 meters). Colorado has 58 named 14ers—more than any other state—ranging from relatively straightforward hikes to serious technical climbs.

When is the best time to climb?

The prime season is mid-June through early September when most trails are snow-free. July and August offer the most stable conditions, but also the highest crowds. Start early—aim to be off the summit by noon to avoid afternoon thunderstorms.

How fit do I need to be?

You should be comfortable hiking 6-10 miles with 3,000-4,000 feet of elevation gain. If you can do that at lower altitude, you're ready for an easier 14er—just expect it to feel harder up high. Start training at least 6-8 weeks before your first attempt.

What does "Class 1-4" mean?

The Yosemite Decimal System rates terrain difficulty:

Class 1: Trail hiking
Class 2: Off-trail, hands for balance
Class 3: Scrambling, exposure
Class 4: Climbing, ropes recommended

Start with Class 1 or easy Class 2 routes for your first 14er.
