420 Denver 2026: The Best Events Happening This Year

The best 420 events in Denver aren’t something you stumble into. They’re something you plan for. Denver treats 4/20 more seriously than any city on earth.

Why? Colorado was the first state to legalize recreational cannabis back in 2012, and Denver has been building on that energy every April since. The 420 events in Denver for 2026 are shaping up to be the biggest slate yet: headline concerts at one of the world’s greatest outdoor venues, a massive street festival in the heart of downtown, cannabis-friendly tours running all week, and enough offbeat experiences to fill a calendar from sunrise to well past midnight.

Whether you’re a local mapping out a full itinerary or a first-timer flying in to see what Denver 420 week is actually about, this guide covers everything worth knowing. We’re organized by category—concerts, the flagship festival, tours and classes, and the events that don’t fit neatly into any box but absolutely deserve your attention. All 420 events in Denver listed here have been verified with dates, times, and links to get tickets. Let’s build your perfect 4/20.

Denver 420 events this year span concerts at Red Rocks Amphitheatre, the flagship Mile High 420 Festival at Civic Center Park, cannabis-friendly tours and classes running daily, wellness experiences, and some genuinely unique one-day-only happenings you won’t find anywhere else.

Quick orientation: Denver 420 week officially runs April 15–23, with most tours and classes operating daily throughout that stretch. The Red Rocks concerts anchor the weekend (April 17–20), and the Mile High 420 Festival at Civic Center Park is the centerpiece of April 20th itself. Multiple events on this list sell out every year, so booking early is your best bet. Here are the 420 events in Denver that matter most.

Red Rocks Amphitheatre is already one of the greatest concert venues on the planet. A 300-foot sandstone monoliths carved by 280 million years of geology, natural acoustics that make every seat feel front-row, and a setting that’s made legends out of everyone from The Beatles to U2. Now put 4/20 weekend on the calendar, and you’ve got something that only happens in Denver. These are the events in Denver on 420 weekend that draw thousands from across the country, and the 2026 lineup at Red Rocks is stacked.

Ice Cube headlines Red Rocks on Monday, April 20th, with Too Short, Big Boi (of Outkast), and Czarface featuring Inspectah Deck of Wu-Tang. Doors open at 5:30 PM, show at 7:00 PM. This is the flagship 420 events in Denver concert—one of hip-hop’s most enduring voices performing at the world’s most iconic outdoor amphitheatre on the one night of the year when the entire city is already celebrating. West Coast and East Coast legends on the same bill, April mountain air, and 9,500 people who all made the same excellent decision. If you only do one thing during Denver 420 week, make it this.

Wiz Khalifa’s “420 Eve On The Rocks” has been an annual Denver Colorado 420 events tradition since 2015, and the 2026 edition features 2 Chainz, Berner, The Underachievers, Chevy Woods, and DJ Bonics. Doors at 4:00 PM, show at 5:30 PM. The earlier start time, the stacked supporting cast, and the anticipation of the day ahead make this the warm-up night that often ends up being the better party. Wiz at Red Rocks on 4/20 eve is a bucket list item for the cannabis community, and the lineup this year is one of his best.

Sublime plays two nights going into 4/20 weekend: Friday, April 17th with Common Kings, and Saturday, April 18th with Pepper. Doors at 5:30 PM, show at 6:30 PM both nights. If you’re spending the full week in Denver, Sublime is the opener that sets the tone for everything that follows. Two nights of laid-back, sun-soaked energy to ease you into the main event. These events in Denver on 420 weekend sell fast, especially the Saturday show.

The Mile High 420 Festival is the heartbeat of the Denver 420 celebration. The event that turns the entire city center into one massive, outdoor, cannabis-friendly gathering. Scheduled for Monday, April 20, 2026, at Civic Center Park, the festival features two stages of live music, art installations, local vendors, educational programming, food trucks, and the kind of community energy that only exists when 50,000 people come together for the same reason.

The full 2026 lineup hasn’t been announced yet. Check milehigh420fest.com for updates as they drop. Previous years have featured headliners like Bone Thugs-N-Harmony, and the event regularly draws the largest crowd of any 420 events in Denver. General admission is $25, with VIP packages at $175 that include a Tommy Chong meet-and-greet, exclusive lounge access with a full bar, and front-stage positioning. Strictly 21+.

Even if you have Red Rocks tickets for the evening, the Mile High 420 Festival is worth a few hours during the day. For first-timers visiting Denver for 420 events in Denver, this is the quintessential experience. Free-flowing, outdoor, right in the center of the action, and the single best place to feel the pulse of what makes the Denver 420 celebration different from everywhere else.

The concerts and festivals are the headliners, but the 420 events in Denver that fill the rest of your week are what turn a good trip into an unforgettable one. All of the following run daily during Denver 420 week (April 15–23).

Daily tours starting at $79/person with multiple departure times from 10 AM through 6:30 PM. The tour includes access to a state-of-the-art cannabis growing facility, party bus or limo transport, and live glass-blowing demonstrations. Book through Colorado Cannabis Tours—this one sells out every year, so don’t wait. Multiple package options are available that bundle hotel stays, transportation, and Red Rocks concert tickets into one booking. Phone: 303-420-TOUR (8687). One of the most popular 420 Denver experiences for visitors who want to see the industry from the inside.

Supplies are provided, just bring clothes you don’t mind getting paint on. Book your session here. Class sizes are extremely limited, which makes early booking essential. This is a great Denver 420 events pick for groups who want a creative, lower-key experience as a midday slot before heading to an evening show.

The most literal interpretation of “Mile High City” you’ll find among Denver Colorado 420 events. $89/person, departing from Colorado Cannabis Tours HQ. Stops include Red Rocks Park (the geological formations, not the concert venue), Lookout Mountain, Buffalo Bill’s grave, the Lariat Loop scenic byway, and the Gold Mill by Coors Brewery. The best way to experience Colorado’s landscape, especially if you want a contrast to the urban festival energy.

Can’t choose? The combo package bundles all three experiences—Cannabis Tour, Puff Pass & Paint, and Mountain Tour—into one 420 Denver booking, available daily April 15–23.

Denver 420 events extend well beyond the big-ticket items. These are the ones that round out your itinerary and give you options for every part of the day, morning to night.

420 Yoga & Meditation at Denver Botanic Gardens — April 20, 9–11 AM. A cannabis-friendly yoga and meditation session at the Botanic Gardens to start your 4/20 grounded before the day gets loud. Finding your center before diving into the Denver 420 celebration is the kind of intentional move that pays dividends by midnight. Details here.

Diva Royale Drag Queen Brunch — April 20, 1:30 PM at Glow Lounge, 631 East Colfax Avenue. Celebrity drag impersonators (Madonna, Beyoncé, Britney Spears, and more) in a brunch matinee. High-energy midday pick for groups who want something completely different between the festival and the concerts. One of the most unexpectedly fun events in Denver on 420.

4/20 at The Roots Collective — Wellness events, vendor fairs, fire dancing, aura photography, tarot readings, ceremonial cacao, and sound baths. The most eclectic lineup of 420 events in Denver on this list, built for the person who wants to wander and discover rather than follow a fixed schedule. More info here.

Colorado Rockies vs. LA Dodgers at Coors Field — April 20, 6:40 PM. Not the most obvious 420 Denver activity, but Coors Field on a spring evening with the mountains in the background is one of the better ways to spend a few hours—and the festive energy of the day carries right into the ballpark. Grab tickets here.

Here’s a suggested itinerary for getting the most out of the Denver 420 celebration without burning out (figuratively):

Morning: Start with yoga at the Botanic Gardens (9 AM) or the Get High on a Mountain Tour for an active, grounded start. 

Midday: Hit the Mile High 420 Festival at Civic Center Park to catch some live music, browse vendors, and soak in the energy. 

Afternoon: Puff, Pass & Paint or the Drag Brunch for something creative between events. 

Evening: Red Rocks. Ice Cube on the 20th, Wiz on the 19th, Sublime on the 17th and 18th. Pick your night (or pick multiple).

A few notes for planning your Denver Colorado 420 events trip: accommodation books fast during 420 week. Cannabis-friendly hotel options through Colorado Cannabis Tours start at $149/night, and availability is extremely limited—book early.

If you have Red Rocks tickets, consider one of the cannabis-friendly transportation packages rather than driving. Parking at Red Rocks during 4/20 weekend is a genuine challenge, and the party bus options mean you don’t have to think about it. Denver 420 events across the board sell out faster than you’d expect. Book everything early, and you’ll spend the week enjoying rather than scrambling.
