Colorado Hiking for Beginners: Your Complete Getting Started Guide

Table of Contents

Welcome to Colorado Hiking

Colorado is one of the best places in the world to hike. With over 300 days of sunshine, 58 peaks above 14,000 feet, and thousands of miles of trails, the Centennial State offers endless opportunities for outdoor adventure. But all that awesomeness comes with some unique challenges that newcomers need to understand.

This guide will walk you through everything you need to know to start hiking in Colorado safely and enjoyably—from dealing with altitude to choosing the right gear to finding trails perfect for beginners.

Understanding Altitude: The Biggest Adjustment

Why Altitude Matters

Denver sits at 5,280 feet—already higher than most cities in the country. Popular trails range from 7,000 to over 14,000 feet. At these elevations, air contains less oxygen (roughly 17% less at 10,000 feet than at sea level), which affects your body in several ways:

  • Your heart and lungs work harder

  • You tire more quickly

  • Dehydration happens faster

  • Headaches and nausea can occur (altitude sickness)

How to Acclimatize

If you're visiting from lower elevations:

  • Day 1-2: Take it easy. Stay at your arrival elevation, hydrate, avoid alcohol

  • Day 2-3: Try an easy, lower-elevation hike (below 9,000 feet)

  • Day 3+: Gradually increase elevation and difficulty

  • Hydrate constantly: Drink 3-4 liters of water daily, even when not active

  • Listen to your body: Headache, nausea, or unusual fatigue means slow down

Altitude Sickness Warning Signs

Mild symptoms (very common):

  • Headache

  • Fatigue

  • Loss of appetite

  • Difficulty sleeping

Serious symptoms (descend immediately):

  • Severe headache not relieved by ibuprofen

  • Confusion or disorientation

  • Loss of coordination

  • Persistent vomiting

  • Shortness of breath at rest

The only cure for altitude sickness is descending to lower elevation.

Essential Gear for Colorado Hiking

The Ten Essentials

Never hit the trail without these basics:

  • Navigation: Trail map and/or GPS app. Don't rely solely on phone—batteries die and service disappears.

  • Sun protection: Sunscreen (SPF 30+), sunglasses, hat. UV rays are 25% stronger at 10,000 feet.

  • Insulation: Extra warm layer even in summer. Mountain temps drop dramatically with elevation and weather changes.

  • Illumination: Headlamp with extra batteries. Getting caught after dark happens more often than you'd think.

  • First aid supplies: Basic kit with blister treatment, pain relief, bandages.

  • Fire: Waterproof matches or lighter. Emergency use only (respect fire bans).

  • Repair tools: Knife or multi-tool, duct tape, gear repair items.

  • Nutrition: Extra hiking food beyond what you think you need.

  • Hydration: More water than planned—1 liter per 2 hours of hiking minimum.

  • Emergency shelter: Space blanket at minimum. Bivy sack for longer trips.

Footwear

Good hiking boots make all the difference on Colorado's rocky trails. For beginners:

  • Start with mid-cut boots for ankle support

  • Ensure waterproof membrane (Gore-Tex or similar)

  • Break them in before hitting serious trails

  • Pair with quality merino wool socks

For easier trails, hiking sandals or trail runners can work in dry conditions.

Clothing Layers

Colorado weather changes fast. The layering system:

  • Base layer: Moisture-wicking synthetic or merino wool (never cotton)

  • Mid layer: Insulating fleece or down

  • Outer layer: Waterproof, windproof shell

Even on warm summer days, bring a rain jacket and warm layer. Temperatures can drop 30°F in an hour when storms roll in.

Trail Etiquette and Rules

Right of Way

  • Uphill hikers have priority – They're working harder and have limited sight lines

  • Yield to horses – Step to the downhill side, speak calmly so horses know you're human

  • Bikes typically yield to hikers – But be alert on multi-use trails

Leave No Trace Principles

  • Plan ahead and prepare – Research trail conditions and regulations

  • Travel on durable surfaces – Stay on established trails

  • Dispose of waste properly – Pack out everything you pack in

  • Leave what you find – Don't pick flowers or take rocks

  • Minimize campfire impacts – Use a stove when possible

  • Respect wildlife – Observe from distance, never feed animals

  • Be considerate of others – Keep noise down, yield appropriately

Trail Closures

Obey all closure signs. Trails close for:

  • Wildlife protection (nesting raptors, denning bears)

  • Erosion repair

  • Fire danger

  • Hazardous conditions

Weather and Timing

The Thunderstorm Rule

Colorado's biggest weather danger: afternoon thunderstorms. From June through August, storms develop almost daily, typically between noon and 4 PM. Lightning kills more people in Colorado than any other natural hazard.

The rule: On any high-elevation hike, plan to be below treeline (approximately 11,500 feet) by noon.

If caught in a storm:

  • Get off ridges, peaks, and exposed areas immediately

  • Descend to lower elevation

  • Avoid lone trees, bodies of water, and metal objects

  • If you can't escape, crouch low with feet together (don't lie flat)

Best Hiking Seasons

Summer (June-August):

Peak season. Higher trails open as snow melts (typically late June for alpine). Watch for afternoon storms. Start early.
Fall (September-October):

Many hikers' favorite season. Cooler temps, smaller crowds, stunning fall colors. Most trails accessible until first major snows (usually late October).
Winter (November-March):

Many lower-elevation trails remain hikeable. Bring appropriate footwear and traction devices. Check conditions before heading out.
Spring (April-May):

Transition season. Lower trails often muddy. Higher trails snow-covered. Check current conditions before any hike.

Checking Conditions

  • AllTrails: Recent trail reports from other hikers

  • 14ers.com: Conditions for high peaks

  • USFS/NPS websites: Official closures and conditions

  • Local hiking Facebook groups: Real-time beta from locals

Wildlife Awareness

Colorado hosts diverse wildlife that you may encounter on trails:

Black Bears

  • Make noise while hiking (especially in dense vegetation)

  • Never run—back away slowly while facing the bear

  • If a black bear attacks, fight back

  • Store food properly (bear canisters required in some areas)

Mountain Lions

  • Rarely seen, but present throughout Colorado

  • Don't run—appear large, maintain eye contact

  • If attacked, fight back aggressively

  • Keep children close

Moose

  • Actually more dangerous than bears—very aggressive

  • Give them wide berth (at least 75 feet)

  • If charged, get behind a tree or rock

  • Most common near water and willows

Elk

  • Generally docile but dangerous during rut (September-October)

  • Keep distance, especially from bulls

Rattlesnakes

  • Common at lower elevations in warm months

  • Watch where you step and put your hands

  • Give them space if encountered—they'll retreat if possible

Building Your Hiking Fitness

Start Where You Are

Don't try to tackle a 10-mile hike your first time out. Build gradually:

  • Week 1-2: 2-3 mile hikes, minimal elevation gain

  • Week 3-4: 4-5 mile hikes, 500-1000 ft gain

  • Week 5-6: 5-7 mile hikes, 1000-1500 ft gain

  • Week 7-8: 7-10 mile hikes, 1500-2500 ft gain

Cross-Training

  • Cardio: Running, cycling, swimming (30-60 min, 3x/week)

  • Leg strength: Squats, lunges, step-ups

  • Stair climbing: Excellent preparation if you don't have hills nearby

  • Core work: Balance and stability help on uneven terrain

Progressive Goals

  • Complete 5-mile hike comfortably

  • Hike above 10,000 feet without issues

  • Complete 8-10 mile day with 2000+ ft gain

  • Attempt first beginner 14er

Frequently Asked Questions

Do I need to be in great shape to hike in Colorado?

You need basic fitness, but you don't need to be an athlete. Start with easier trails and build up. The main challenge is altitude—give yourself time to adjust.

Can I hike alone?

Many people do, but solo hiking carries more risk. If you hike alone: tell someone your plans, stick to well-traveled trails, carry the 10 essentials, and know your limits.

What if I need to use the bathroom on the trail?

For #1: go at least 200 feet from trails and water. For #2: dig a cat hole 6-8 inches deep, at least 200 feet from trails and water. Pack out toilet paper or use natural alternatives.

How much water should I bring?

Plan for 1 liter per 2 hours of hiking, more in heat or at high elevation. A 6-hour hike needs 3+ liters. Always bring more than you think you'll need.

When is the best time to visit Colorado for hiking?

July-September offers the most accessible trails and best weather. Fall (late September-early October) brings stunning colors and fewer crowds. Spring and early summer mean snow at higher elevations.
