Essential Travel Tips
Layers are your best friend in Colorado, no matter the season! Mornings can be chilly even in summer, and mountain weather changes on a dime. Think t-shirts, a fleece or puffy jacket, and a waterproof shell – you'll thank yourself when you're hiking or exploring mountain towns.
Embrace happy hour for dining out, especially in Denver and mountain resort towns. Many restaurants offer discounted drinks and appetizers from around 3-6 PM, which can significantly cut down your food bill. Look for places advertising 'apres-ski' specials in winter or 'sundowner' deals in summer.
If you're flying into Denver International Airport (DEN) and heading to the mountains, consider the 'Snowstang' bus service. It's a budget-friendly way to reach popular ski resorts like Winter Park and Steamboat Springs, saving you the hassle and expense of renting a car and dealing with mountain driving.
Altitude sickness is real, so take it easy your first day or two. Stay hydrated (drink more water than you think you need!), avoid alcohol initially, and don't overexert yourself. If you're heading straight to a high-altitude town like Breckenridge or Estes Park, consider downloading an altitude sickness app like 'Altitude Sickness' to track symptoms.
Tipping is expected here, just like in most of the US, but be generous with service staff, especially in tourist areas. A 15-20% tip for restaurant servers, bartenders, and tour guides is standard. Remember, many service workers rely heavily on tips for their income.
Don't leave Colorado without trying some green chili! It's a hearty stew, often pork-based, with roasted green chilies and a rich broth, and it's a local comfort food staple. You'll find it on menus everywhere from diners to upscale restaurants, often served with tortillas or over burritos.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Frequently Asked Questions
When is the absolute best time to visit Colorado if I want to experience both stunning fall colors and good hiking weather?
For that perfect blend of vibrant aspen leaves and comfortable hiking temperatures, aim for mid-to-late September. The Rockies really put on a show then, with golden hues blanketing the mountainsides, and you'll often find crisp, sunny days ideal for hitting the trails before the snow starts to fly in earnest.
I'm planning a road trip through the mountains. What's a realistic pace to avoid feeling rushed, and are there any must-do scenic byways?
Don't try to cram too much in! I'd suggest dedicating at least two days to explore a single region, like the San Juan Skyway in southwestern Colorado, which is truly breathtaking. Factor in extra time for spontaneous stops – you'll want to pull over constantly for photos and short hikes, trust me.
Beyond Denver and Aspen, what's a charming mountain town that offers a more authentic Colorado experience?
You absolutely must check out Crested Butte. It's known as the 'last great ski town' and retains a fantastic, laid-back vibe with a vibrant main street full of independent shops and restaurants. In the summer, the wildflowers are incredible, and it's a gateway to some amazing backcountry adventures.
I'm concerned about altitude sickness. What are your best tips for acclimatizing and enjoying my trip without feeling unwell?
Hydration is key, and I mean *lots* of water, starting even before you arrive. Take it easy on your first day – avoid strenuous activity and alcohol, and opt for lighter meals. Many locals swear by drinking beet juice for its nitrates, which can help with oxygen flow, though simply pacing yourself is the most reliable strategy.
What's a common local custom or piece of etiquette I should be aware of when visiting smaller mountain communities?
In the smaller towns, a friendly wave or nod to people you pass, whether on the street or on a trail, is deeply ingrained. It's a sign of respect and community, so don't be surprised if you get a wave from a stranger – just wave back! It makes the whole experience feel much more welcoming.
I'm visiting in the winter. Besides skiing, what are some unique winter activities that don't require expert-level snow sports skills?
Snowshoeing is fantastic and much more accessible than you might think; many resorts offer rentals and guided tours on groomed trails. Another favorite of mine is visiting a natural hot spring, like Strawberry Park Hot Springs near Steamboat Springs, especially after a day in the snow – it's pure bliss under the stars.
