The Most Cannabis-Friendly State in America

Colorado welcomes over 80 million visitors per year, and cannabis tourism contributes an estimated $423 million annually to the state economy. With a decade-plus of legal recreational sales, the state offers the deepest dispensary market, the most established tour operators, nascent but growing consumption lounges, and the cultural infrastructure of a place that has lived with legal cannabis longer than anywhere else on Earth.

When to Visit

Colorado cannabis tourism peaks around April 20 (the Mile High 420 Festival draws thousands to Civic Center Park) and during ski season (December–April). Summer brings hiking, festivals, and Red Rocks concerts. The fall shoulder season (September–November) offers excellent weather, lower hotel rates, and shorter dispensary lines.
