Essential Travel Tips
Pack layers, no matter the season! Colorado weather can change on a dime. Think t-shirts, a fleece or puffy jacket, and a waterproof shell. Even in summer, mountain mornings and evenings can be chilly, and afternoon thunderstorms are common.
Renting a car is usually best for exploring beyond Denver, but be prepared for mountain driving. If you're visiting during winter, ensure your rental has all-wheel drive or 4WD, and always check road conditions on COTrip.org before heading out, especially for mountain passes.
Take advantage of happy hour deals for dining out, especially in ski towns where restaurant prices can be steep. Many places offer discounted appetizers and drinks from late afternoon into early evening, which can significantly cut down on your food budget.
Acclimatize to the altitude slowly to avoid altitude sickness. Drink plenty of water (more than you think you need!), limit alcohol on your first day or two, and avoid strenuous activity right away. If you're flying into Denver (5,280 ft), consider spending your first night there before heading to higher elevations like Breckenridge or Vail.
Tipping is customary here, just like in most of the US. Don't forget to tip service staff at restaurants, bars, hotels, and for any tours or activities you enjoy. A 15-20% tip is standard for good service.
Try some local Colorado specialties! Look for dishes featuring bison, elk, or trout. Green chili (often spelled 'chile') is a regional favorite, served as a stew or smothered over burritos – it's a must-try, especially in Southern Colorado.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Getting Around Colorado, USA
Denver International Airport (DEN) Ground Transportation
Upon arrival at DEN, you have several options to get into Denver and beyond. The most efficient is the A-Line commuter train, which connects directly to Union Station in downtown Denver. Ride-sharing services and taxis are also readily available.
Colorado Mountain Express (CME) Shuttles
For travelers heading to popular mountain towns like Vail, Breckenridge, or Aspen, CME offers shared or private shuttle services directly from DEN. This is a convenient way to avoid renting a car and dealing with mountain driving.
Bustang Bus Service
Bustang is Colorado's state-run intercity bus service, connecting major cities and towns across the state, including routes to mountain destinations. It's a more budget-friendly alternative to private shuttles or rental cars.
Rental Cars with 4WD/AWD
While not always necessary in Denver, a rental car is often essential for exploring the vastness of Colorado, especially if you plan to visit national parks or remote areas. Opting for a 4WD or AWD vehicle is highly recommended for mountain driving, particularly outside of summer.
Regional Transit Authorities (RTAs)
Beyond Denver's RTD, many mountain towns and regions have their own local bus systems that connect within the community and sometimes to neighboring towns. These are invaluable for getting around once you've reached your destination without a car.

Frequently Asked Questions
When is the absolute best time to visit Colorado if I want to experience both stunning fall colors and avoid the biggest crowds?
For that sweet spot of vibrant autumn foliage and fewer people, aim for the last two weeks of September or the first week of October. This is when the aspens are typically at their peak golden glory, especially at higher elevations, and you'll miss the summer rush and the early ski season crowds. Just be prepared for crisp, cool weather – pack layers!
I'm planning a road trip through the Rockies. What's the deal with driving in the mountains, especially in winter?
Driving in Colorado can be breathtaking, but it demands respect, especially outside of summer. Always check road conditions before you leave, particularly for mountain passes like Loveland or Vail, as they can close unexpectedly due to snow. If you're visiting between October and May, a 4WD or AWD vehicle is highly recommended, and carrying chains might even be required during severe weather. Don't underestimate the altitude – take it easy on your first day to acclimate.
Beyond Denver and Aspen, what's a truly unique Colorado experience that most tourists miss?
You absolutely must explore the San Juan Mountains in southwestern Colorado, particularly around towns like Telluride or Ouray. The scenery is dramatic, with jagged peaks and historic mining towns clinging to hillsides. Consider a scenic drive on the Million Dollar Highway (US-550) – it's not for the faint of heart, but the views are unparalleled, and you'll feel like you've stepped back in time.
I've heard about the altitude. How serious is it, and what's the best way to prepare?
Altitude sickness is a real thing in Colorado, as much of the state sits above 5,000 feet. The best advice I can give is to take it easy your first day or two: avoid strenuous activity, drink TONS of water (more than you think you need!), and limit alcohol. Many locals swear by avoiding heavy meals initially. If you feel symptoms like headache or nausea, descend to a lower elevation if possible and rest.
What's a local Colorado 'must-try' food or drink that isn't just a generic 'American' dish?
You've got to try some Rocky Mountain Oysters – they're actually bull testicles, but when fried, they're surprisingly delicious and a true Colorado culinary adventure! For drinks, seek out local craft breweries; Colorado has a thriving beer scene, with everything from crisp lagers to robust stouts. Many small towns have fantastic breweries that are central to the community.
