17 essential tips for your Colorado visit

Colorado is a destination that consistently lands on everyone’s must-visit list, and it’s easy to see why.

From its stunning mountains and thrilling outdoor activities to the laid-back charm of its ski towns and bustling cities filled with amazing art and cuisine, Colorado has a unique way of drawing you in.

Though your experience in this remarkable state is likely to be smooth, there are a few insider tips worth knowing before you embark on your adventure. Here are our top suggestions to help you make the most of your time in Colorado.

1. Dress in layers

Colorado's weather can shift rapidly, especially in the mountains, so be sure to pack layers! A waterproof jacket, fleece, warm hat, and a brimmed hat are essential year-round, and if you’re visiting in winter, don’t forget your cold-weather gear.

2. Stay hydrated

Bring a reusable water bottle. Staying hydrated is crucial in Colorado, where high altitudes, dry air, intense sunshine, and plenty of outdoor activities can lead to dehydration. Drinking enough water will also help you adjust more easily to the altitude if you're not used to it. Plus, refilling your water bottle or Hydro Flask saves money and reduces plastic waste compared to buying bottled water each time you’re thirsty.

3. Reserve a rental car ahead of time

To fully enjoy the sights and activities Colorado has to offer, having a car is incredibly convenient. Major international rental companies operate in the state’s airports and cities, and booking in advance will give you a better selection of vehicles.

Once you hit the open road, you'll notice that Colorado’s highways are well-kept. There's typically no need to invest in a 4WD unless you're venturing into the backcountry or anticipate driving through heavy snow. If you visit in winter, be sure to keep a cold-weather emergency kit in your car, including food, water, and blankets.

4. Book your campsite early

Summer camping is a favorite pastime for both locals and visitors in Colorado, with breathtaking locations ranging from rugged canyons to lush forests. Make sure to secure your reservation early, especially if you're planning to visit one of the state’s four national parks, particularly during summer or school vacation periods. Reservations for camping at Colorado's state parks can be made up to six months in advance.

5. Purchase pro sports tickets in advance

Professional sports are hugely popular in Colorado, with teams like the Broncos (NFL), Avalanche (NHL), Nuggets (NBA), Rockies (MLB), and Rapids (MLS) all based in Denver. Tickets, especially for Broncos and Avs games, tend to sell out quickly—secure your tickets as soon as you know your travel dates. If you’re on a budget, consider catching a Rockies baseball game; bleacher seats (the Rockpile) are available starting at just $6.

6. Verify airline equipment restrictions

If you’re planning to bring your skis, snowboard, mountain bike, or any other large sports gear to Colorado, check the baggage policies of your airline when you book your flight. While many airlines have eliminated oversize luggage fees and often don’t require hard-shell cases, it’s always best to confirm beforehand to avoid any surprises.

7. Don your fluffiest jacket

Casual attire reigns supreme in Colorado, with jeans and puffy jackets forming the local uniform. In fact, jeans are rarely unsuitable, except maybe on the ski slopes. For a night out, elevate your look from a t-shirt to a button-down shirt or blouse, and finish off with your best sneakers (heels work too).

8. Savor the local craft beer

Coloradans are passionate about craft brews, particularly hoppy India Pale Ales. With an abundance of locally brewed options, it would be a missed opportunity not to enjoy one. If you opt for mainstream brands, make sure it’s a Coors, brewed in Golden, Colorado.

9. Move gently in the great outdoors

Colorado treasures its natural landscapes, from majestic mountains and rushing rivers to soaring mesas and sunlit plains, making it impossible not to be captivated by the surroundings. Follow the locals' lead and protect this beauty by adhering to guidelines: respect fire bans and 'no swimming' signs, stay on designated trails, carry out what you bring in (plus any litter you encounter), and avoid carving your name into rocks or trees.

10. Choose your words wisely

Political beliefs in Colorado are diverse, with some opinions held very passionately. Be mindful when discussing politics, and don’t assume that others share your views, especially if you’re from a larger city. A helpful tip is to observe bumper stickers and billboards for clues about local political sentiments. Generally, Denver and Boulder lean liberal, while Colorado Springs is more conservative, and mountain towns can vary widely.

11. Enjoy your Rocky Mountain high (but stay within the law)

The unmistakable aroma of marijuana is a common fragrance in Colorado, and it’s easy and legal to partake for those aged 21 and over, as long as you adhere to the regulations (for more details, check out the Colorado Pot Guide).

• Only purchase from licensed dispensaries, easily identified by their green crosses. Bring your ID, and remember they accept cash only.

• Avoid using cannabis in public areas. Consuming cannabis—whether smoking or edibles—is illegal in parks, bars, restaurants, and concert venues (regardless of any scents you may encounter).

• Never drive under the influence; it’s dangerous and you could face a DUI charge if caught.

• Don’t smoke in your vehicle. Having an open marijuana container in your car is illegal. Store your supplies in the trunk and wait until you arrive at your destination to use them.

• Before using cannabis in your hotel or Airbnb, confirm that the property is ‘420 friendly.’ If it’s not allowed, you risk being evicted or incurring hefty cleaning fees.

12. Take your time ascending

Altitude sickness is a real concern in Colorado, with elevations ranging from 3,300 feet to 14,400 feet. Visitors often experience fatigue and mild headaches, and you may also feel nauseous or become easily winded. If you're planning to venture to higher altitudes, ascend gradually to prevent Acute Mountain Sickness (AMS).

Take your time on steep climbs, stay hydrated, and give yourself a few days to adjust to the altitude. Some ski resorts even offer disposable oxygen tanks to assist with acclimatization. Reducing alcohol consumption is beneficial too—after all, drinks have a stronger effect at higher elevations! If you experience severe or persistent nausea, headaches, or dizziness, descend to a lower altitude and seek medical advice.

13. Protect yourself from the sun

With around 300 days of sunshine each year and high elevations throughout much of the state, the sun can be particularly intense in Colorado. Make sure to cover up, apply sunscreen, and wear sunglasses. A wide-brimmed hat is also a wise accessory to have. If you're hitting the slopes, don’t forget to use SPF-infused lip balm—there’s nothing worse than having sunburned lips!

14. Be smart about wildlife encounters

With countless opportunities to explore the great outdoors, encounters with majestic American wildlife are quite possible. Check in with park rangers and heed their advice on what to do if you cross paths with one of the Rocky Mountains' larger inhabitants. Even deer and mountain goats can be hazardous to vehicles and cyclists if you stumble upon them unexpectedly on a remote trail.

Making noise while hiking is a smart move—singing or whistling can help alert animals to your presence. If you come across a large animal like a moose, mountain lion, or black bear, back away slowly without making eye contact; do not run. Carrying bear spray when hiking in wilderness areas is also a wise precaution.

15. Be ready for varying road conditions

Weekends and holidays bring significant traffic to Colorado’s roads, as both locals and visitors head to the mountains, so be prepared for delays. In winter, snowstorms can create hazardous driving conditions—state law mandates that vehicles have adequate tire tread and either all-weather tires or All-Weather Drive when driving in stormy conditions. Always check road and weather updates before you leave and keep a set of auto-socks (an improved alternative to chains) in your vehicle if you're going to the mountains.

It’s smart to brace for unexpected delays (and the possibility of getting stuck in snow) by packing snacks and drinks, along with blankets, a mobile phone, and a power bank for emergencies. You might also want to have a snow shovel, flares, and an extra pair of gloves and boots in your trunk, just in case.

16. Keep an eye out for gray clouds

Afternoon lightning poses a real threat in the mountains, particularly during summer. Start your summit hikes early and ensure you're well below the peaks and passes by noon. If you spot gray thunderclouds, don’t hesitate to turn back—it could save your life.

17. Respect the risk of avalanches

Avalanches are a reality in Colorado's backcountry, claiming multiple lives each year—even those with extensive outdoor experience can be at risk. Engaging in backcountry skiing, snowboarding, or snowshoeing necessitates specialized training and equipment; visit the Colorado Avalanche Information Center for guidance, and always go with a knowledgeable partner or guide.
