Tips for Hiking in Colorado
Before you head out on any Colorado hike, keep these tips in mind:
Start early! Afternoon thunderstorms are dangerous and kill hikers each year. Not to mention, if you start before the sun rises, you’ll have these popular Colorado hikes to yourself.
Acclimatize properly. Hiking at altitude is tough work. Plan on resting more and drinking water often.
Follow Leave No Trace and pick up after yourself (bonus points if you pick up other’s waste too!).
Don’t poop above treeline. Waste does not break down this high up. Carry a wag bag and pack your poop out or stay below the trees!
Check and double-check the weather. Storms come in quickly and the weather changes on a dime here. Always understand that the weather generally comes from the west, and keep an eye on storms.
