California isn’t just the birthplace of legal medical cannabis in the U.S.—it’s the epicenter of weed culture. With sun-soaked landscapes, a vibrant community of cultivators and connoisseurs, and some of the most progressive cannabis laws in the world, it’s no surprise the Golden State plays host to some of the best cannabis festivals around.
Whether you’re into live music, mind-blowing edibles, glass-blowing competitions, or just soaking up good vibes with fellow cannabis enthusiasts, there’s a festival waiting for you. Here are five must-attend cannabis festivals lighting up California in 2025.
1. Emerald Cup – Santa Rosa / Southern California
Known as the “Academy Awards of Cannabis,” The Emerald Cup has become a legendary event in the industry. Founded in 2003 as a humble grower’s contest in the Emerald Triangle, the festival has evolved into a multi-day celebration of sustainable cannabis, culture, and innovation.
Split between NorCal and SoCal venues, Emerald Cup features expert panels, music performances, and the coveted Emerald Cup Awards, judged on everything from terpenes to ethical farming. It’s where legacy meets the future.
Next event: Spring 2025 (Dates TBD)

2. Grass Lands at Outside Lands – San Francisco
Who says music festivals and cannabis don’t mix? Outside Lands in San Francisco’s Golden Gate Park has a dedicated cannabis experience called Grass Lands—a legal, fully-operational cannabis marketplace within the festival.
Here, attendees (21+) can explore dozens of brands, sample products, take workshops, and chill in consumption-friendly lounges—all while enjoying sets from top-tier artists like Kendrick Lamar and The Strokes.
Next event: August 2025

3. Hall of Flowers – Palm Springs & Santa Rosa
This one’s for the industry insiders—and those who want a sneak peek into what’s next. Hall of Flowers is a B2B cannabis trade show like no other, blending polished design with retail-ready weed brands and some of the biggest names in cannabis media.
While not a traditional festival with concerts and beer gardens, it offers a curated, boutique experience of the cannabis world—from luxurious vapes to small-batch flower.
Next events: March (Palm Springs) & September (Santa Rosa)

4. 420 Hippie Hill – San Francisco
There’s no party like a Hippie Hill party. Every April 20th, thousands of people flock to Robin Williams Meadow in Golden Gate Park for a free, unofficial, yet fully embraced 420 celebration. It’s a smoky, vibrant grassroots gathering full of food trucks, live DJs, and clouds of dank aromas.
While not “licensed” in the traditional sense, city officials have cooperated in recent years to provide safety, sanitation, and vendor oversight. Think of it as the people’s cannabis festival.
Next event: April 20, 2025

5. Kushstock Festival – Adelanto, CA
What began in 2016 as an underground celebration in the High Desert has become one of SoCal’s largest and most free-spirited cannabis gatherings. Kushstock is a 100% free-to-attend, 21+ festival featuring live music, BMX shows, glass art, and, of course, a massive lineup of cannabis brands and vendors.
It’s wild, unapologetically stoney, and a great way to tap into California’s cannabis scene without breaking the bank.
Next event: October 2025 (TBD)
