At the base of the Rocky Mountains sits the biggest pull for travelers to Colorado: Denver. Long relegated as a flyover city, Denver has experienced a boom over the last decade thanks to its expanding skyline, increasingly efficient public transit, budding food and nightlife scenes, epic outdoor opportunities, and, of course, the best 420 culture in the entire United States. A small-ish city of three million, Denver is an ideal weekend destination for hikers, skiers, artsy hipsters, beer drinkers, burger fanatics, cannabis enthusiasts, and anyone else who’s looking for the perfect mix of heart-pumping adventure and ultra-chill vibes.
