DENVER — Denver is preparing to host a rap battle of epic proportions, with two massive concerts slated to light up the city on Monday, April 20, otherwise known as the cannabis high holiday 420.

The long-running Mile High 420 Festival comes to Civic Center Park with rappers Juicy J, Paul Wall, Mike Jones, That Mexican OT and Trap Dickey. Meanwhile, Red Rocks Amphitheatre’s signature 420 on the Rocks concert will be headlined by Snoop Dogg and Ice Cube, with support from Too Short, and Czarface. The latter is a supergroup featuring Inspectah Deck of the Wu-Tang Clan and hip-hop duo 7L & Esoteric.

How will fans decide which one to attend? Ticket price might be a factor.

Though Mile High 420 Fest was traditionally a free event for adults 21 and up, organizers began charging for tickets in 2025. This year, it costs $30 for general admission entry or $185 for VIP, which includes access to a reserved lounge, private full bar, the front of the stage and a swag bag of 420 gifts. (Tickets available at milehigh420fest.com.)

420 on the Rocks is pricier, with tickets starting at $199. (Tickets available at axs.com.)

Given that 420 falls on a Monday this year, timing could also play into decisions.

Mile High 420 Fest is typically a day party with a plume of smoke emerging from the crowd during a communal celebration around 4:20 p.m. The 2026 schedule has not yet been released, though the website says Juicy J performs at 4:20 p.m. From a logistics standpoint, it’s also unclear how the festival plans to work around construction currently underway at Civic Center Park. (The festival has not responded to inquiries from The Denver Post about what attendees can expect.)

By contrast, the 420 on the Rocks show starts at 7 p.m. (doors at 5:30 p.m.), making it a nightcap to the day. Come to think of it, that means locals could potentially hit both parties — if their stash lasts that long.
