One of the most unmissable things to do in Colorado is to hit up the Rocky Mountains for a spot of hiking. It’s a no-brainer. An hour and a half drive outside of Denver, join one of the many, many trails. We’d recommend Twin Sisters Peak (which is even more reachable if you’re staying in Boulder). It’s quite challenging though and will take pretty much all day.
The International Church of Cannabis is one thing, but the Cathedral Basilica of the Immaculate Conception is another level entirely. Conceived in the mid-19th century and finished by 1911 and costing a cool half a million dollars, this impressive cathedral is a pretty impressive place to visit. It’s the kind of thing you might expect, well, not in the USA, but here it is in all its Catholic glory.
When you’re away with kids, the top priority (basically) is to keep ’em entertained and at Denver Museum of Nature and Science, you can do just that. We mean, what pre-teen adolescent doesn’t love space? Or dinosaurs? Because there’s plenty of all that stuff going on here. The planetarium is pretty cool actually. It even makes for one of the best things to do in Colorado when it rains because there’s nothing worse than getting totally rained off indoors with bored, restless kids practically scuttling up the walls of your hotel.
Artistic visionaries and the spirit of rogue ingenuity define this route that starts in Denver, winds through the plains of southeastern Wyoming, and finishes in Alliance, Nebraska.

Why go? Absorb the Beaux Arts aura of the majestic, barrel-vaulted Great Hall while sipping local craft beers in the retro-toned Terminal Bar or cocktails on the mezzanine of the glamorous Cooper Lounge. Score a seat at Stoic & Genuine’s chef’s counter to indulge in sharp twists on seafood classics or treat yourself to a feast at Mercantile Dining & Provision, where farmhouse substance meets cosmopolitan style. 
Denver may have a good food scene, but so does the city of Boulder. One of the best places to see this in action is at the Boulder Farmers Market. Dating back to 1972, it’s open on Saturdays and Wednesdays and serves up a load of fresh produce to marvel at, kooky crafts to pick up, and some excellent live music – we mean, who doesn’t love a good market?
Past visitors raved about the Denver Art Museum, praising its diverse and varied collections and the museum's ability to appeal to kids through interactive activities.
