Rocky Mountain National Park is arguably the most accessible park in the Western USA, being only a few hours away from Denver. It is also one of the most impressive national parks in the entire nation and receives a boatload of visitors. Spend a day exploring this park, either renting a car to drive the superlative Trail Ridge Road (summer only) or via one of the many trails.
It’s not every day you get to go see how actual money gets made, so why not head on over to Denver Mint? And thankfully the only cash involved is the stuff you’ll see being made: you have to part with anything because it’s free. It ain’t just about money though – it’s history. Dating back to 1792, Denver Mint is the sole manufacturer of all those dimes and dollars in your pocket. That’s a huge claim to fame and makes it easily one of the most interesting, and most unusual, things to do in Colorado. If you’re a history fan, or if you’re looking for stuff to do in Denver when it’s raining, this is a must.

Have you heard of The Shining? If you’re a fan of the film, of Stephen King, or of spooky sh*t in general, we definitely recommend going to the place where it all began: the Stanley Hotel. It’s here where King got the inspiration for the book, after apparently experiencing some weird stuff going on at night in room 217. For one of the best things to do in Colorado at night, book a room here, stay the night, and see what the heck’s going on.
Why go? Cucci has a knack for designing restaurants that owe some of their success to a quirky backstory. Ophelia’s Electric Soapbox is an eye-poppingly risqué tribute to its building’s history, while what was once a mid-century garage now informs the vintage cool of Root Down. Take it all in over a meal that showcases the Edible Beats restaurant group’s focus on earth- and lifestyle-conscious food and drinks. Oh – and if you want to be entertained by more than just delicious edibles, it's worth sneaking a peek at Ophelia’s events calendar, where you'll find everything from singer/songwriter evenings and pizza disco parties to comedy showcases and open mics.
Colorado definitely isn’t some hidden island out there in the ocean. But it is a vast American state which will constantly throw up surprises and you’ll always be finding off the beaten track things to do in Colorado. From its nature to its urban centres, this state could keep you occupied for a long time. And whether you’re looking for stuff to do with your family, a few romantic things to do with your partner, or if you just wanted to find a few kooky, weird things to do in Colorado, our guide has you covered with some pretty interesting activities. Make sure you set aside plenty of time, though!

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. 
Running continuously since 1882, the Durango and Silverton Narrow Gauge Railroad is genuinely one of the most scenic railroads in the whole of the USA. Riding the railroad is one of the more touristy things to do in Colorado, but we literally don’t care: it’s amazing. Hop on one of the coaches straight outta the 1880s (the interiors are immense; get ready to blow up your Instagram) and be whisked into a past of frontiersmen and cowboys.
Seed & Smith is a good place to start learning about it the industry in America, but in the state of Colorado particularly. They even have a “sniff station” here to get your nostrils full of 420-friendly scents. Taking a weed tour is definitely one of the more unusual things to do in Colorado and one for anybody who’s interested in just how the heck it all works.

Why go? In 1983, a little-known Irish band happened to film a performance at what you might call nature’s own music hall—and the rest, as U2 fans know, is rock history. Of course, it also serves as one of the world’s most breathtaking gyms, where runners get super-sweaty attempting to tackle the seemingly endless staircases and hikers hit the trails through the surrounding 868-acre park. 

If a Jeep or other 4×4 just won’t cut it for you, and you’re actually more of an outdoors person who likes to be in it rather than just drive through it, how about climbing? Garden of the Gods also has some absolutely awesome climbing routes (Montezuma’s Tower is ah-mazing) and makes for one of the best adventurous things to do in Colorado. We mean, how could you not get better views of this stunning location without climbing up high? It’s not just for veteran climbers: people with different experience levels can get on board with this one.
Dating back to well to almost 1,000 years ago, the cliff dwellings at Mesa Verde National Park represents some of the best-preserved of their kind. In fact, they’re the best preserved in all of North America. Who built them? The Puebloans did, indigenous people of this region of the Americas who constructed the stunning cliff-based buildings back in the 1190s AD. These have been given names like Balcony House, and Cliff Palace, which has 150 rooms. For one of the most interesting things to do in Colorado, ranger-led tours can (and should – trust us) be arranged before your visit.

It might not be the cheapest thing to do in Colorado, but heading up to the Peaks Lounge at the top of the Hyatt Regency is definitely one of the best things to do in Denver at night. The view from up here on the 27th floor of the Hyatt building offers up an immense vista of the city skyline. Have cocktails as the sunsets and watch the buildings of Denver begin to glitter in an urban light show that you really should capture to show off just where you are and what you’re doing. To top it all off, Peaks Lounge has great service (as it should) and an awesome ambience. Definitely one of the best things to do in Colorado for couples, actually.

Speaking of couples, here’s an awesome thing for couples to do in Colorado: a sunrise hot air balloon ride. Yeah, yeah, we know, you have to get up super early to actually experience this, but honestly, it’s worth it. On a clear day, you’ll be able to see 100 miles in all directions as you watch the Rocky Mountains gradually light up as the sun rises. You’ll even be able to spot wildlife like deer and coyotes from the basket as you float on by. Awesome.
The Royal Gorge is a pretty epic spot. Hosting the tallest suspension bridge in the world, the soaring walls of this cut in the Earth tower 1,000 feet above the raging Arkansas River. If you’re up for the challenge, how about some white river rafting to best soak up the dramatic natural scenery? Even though it’s one of the most adventurous things you can do in Colorado if you’re a first-timer, don’t worry: it can be done! It’s the sort of experience that’ll either make you think, “wow, I really need to do this again!” … or “that was terrifying, let’s never do that again.” Who knows? But you won’t know unless you try!
That’s right: the Georgetown Loop Railroad takes you out of the city on a narrow gauge railway, along and across Clear Creek, for some prime mountain views on a history-laden steam train, complete with vintage carriages to match. Any sort of person wanting to soak up the past of this area will enjoy this one, but if you’re a train fan… this day trip in Colorado is going to make your head explode. In a good way.
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.

Named for Denver's famed beer, Coors Field in Denver's LoDo district is home to Major League Baseball's Colorado Rockies. The stadium occupies a whopping 76 acres and has the capacity for more than 50,000 people. Of course, the main reason to come to Coors Field is to catch a game, but there's more to this stadium than a diamond. Whether you're traveling with children or alone, be sure to spend some time at the Interactive Area, where you can test your skills in the video batting cages and the Speed Pitch area. And if you've left the kids at home, take the opportunity to sample some of Denver's local brews on the Rooftop, a 38,000-square-foot platform with fantastic views of the field and downtown Denver. If the weather isn't cooperating, pay a visit to the on-site SandLot brewery instead.
