You step off the plane in Denver, ready for adventure. The air is crisp, the mountains look unreal, and your excitement is through the roof. Maybe you’ve got a hike planned. Perhaps you are here for the food scene. Or maybe you are here for popular brew tours – because nothing says vacation like sipping a locally brewed IPA while taking in the city’s energy.

But then, reality hits. Your lips are dry, your head is pounding, and you packed all the wrong clothes. Colorado’s weather just pulled a fast one on you. One minute, it’s sunny and warm. The next? Wind, rain, and a 20-degree temperature drop.

Don’t be that person shivering in a t-shirt, regretting life choices, and eager to explore Denver brew tours. Pack smart, and you’ll actually enjoy your trip instead of spending it uncomfortable and unprepared. Let’s break down what you really need to bring.

Layers: Because Colorado’s Weather is a Chaos Machine

Colorado does not care what season it is. It does what it wants. That is why layering is not a suggestion—it is survival.

Start with a solid base layer. Add a cozy mid-layer, like a hoodie. And always—always—bring a lightweight, waterproof jacket.

Hydration: Because Altitude Will Wreck You If You’re Not Careful

You might think you drink enough water. You don’t. Not at 5,280 feet in Denver. And definitely not at 10,000 feet if you’re venturing into the mountains.

Altitude sickness is no joke. Headaches, dizziness, exhaustion—it’s a real buzzkill. Chug water like it’s your job. Bring a refillable water bottle and sip constantly.

Shoes: Because Blisters and Frozen Toes Ruin Vacations

Flip-flops are a bad idea. Even if you’re sticking to the city, you will be walking a lot. You need comfortable sneakers, at the very least.

Are you planning a hike? Get real hiking boots. Trails here are not flat, and you will want solid footing.

A Backpack: Because Carrying Everything in Your Pockets is Dumb

You will need a small daypack. Not some giant, overstuffed hiking pack—something to hold your essentials. Water bottle, snacks, an extra layer, and a portable phone charger.

If you’re joining a guided tour, like one of the many that Denver tour operators offer, a backpack makes it easy to stash your stuff so you’re not juggling everything in your hands. Plus, it frees you up for more important things – like grabbing a beer, snapping photos, or just soaking in the view.

Tech & Extras: The Things You’ll Wish You Had

• Portable charger – Your phone will be working overtime for GPS, photos, and brewery searches. Don’t let it die when you need it most.
• Sunscreen – Yes, even in winter. The sun is stronger at high altitudes, and a sunburn at 10,000 feet is brutal.
• Sunglasses – Colorado is sunny all the time. Your eyes will thank you.
• National Parks Pass – If you’re hitting places like Rocky Mountain National Park, this can save you money.

Let the Pros Handle the Logistics

If you want to explore without the stress of planning every detail, local tour operators are a lifesaver. They know the best spots, handle the driving (a huge win if you’re hitting breweries), and make sure you don’t miss out on the good stuff.

Colorado is incredible—but only if you pack right. Bring what you need, drink a ton of water, and don’t underestimate the weather. That way, you can focus on the important things—like hiking, sightseeing, and raising a glass on a Denver brew tour experience.
