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.
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.
Do you like food? Good, because Denver has a real vibrant culinary landscape going on and you should definitely make it your quest (we’re using that word) to discover what the cuisine here is on offer. There’s a lot of history layered in between the different dishes on offer, making it a good way to find out about who made the city what it is. Think Mexican and indigenous influences. Try shishito peppera la plancha combined with sheep’s cheese, Rocky Mountain oysters (yes, that’s a thing), Olathe Sweet Corn, to name just a few.
Did you know that you can actually walk along dinosaur tracks? Well, you can and you can do it in this very state. It’s honestly so cool and one of the more… off the beaten track things to do in Colorado. There are over 1,300 tracks making up the Picketwire Canyon Trackway and come from a line-up of famous dinosaurs like apatosaurus and allosaurus.
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.
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.
Visiting the Molly Brown House is an architectural gem in itself; it was built in 1887 and definitely takes you back in time. But it’s not just one of the best things to do in Colorado for its admittedly pretty facades. This was the house of “The Unsinkable Molly Brown”. How’d she get that name, you ask? Simply by surviving the sinking of the Titanic, that’s how. She happened to be traveling alone in a 1st class cabin at the time (a pioneering solo traveler). Pretty amazing – and you can earn all about her here. Perfect for any fan of Titanic.

A great way to get an adrenaline rush and a great vista without having to climb up the side of a sheer cliff face is ziplining. It’s one of our most favourite things. Colorado isn’t short of places to get your fill of this sport (is it a sport?). Pretty epic, and one of the best adventurous things to do in Colorado. Head on over to Manitou Springs for a collection (5 to be exact) of some awesome ziplines strung out over the foothills at the bottom of the famous Pike’s Peak. Some of these ziplines are over 600ft long, which is perfect for all you adrenaline junkies out there.

Why go? You can either shop for vintage wares, weed or both: These days, SoBo is also called the Green Mile, reflecting the influx of marijuana dispensaries. The quirky shopping experience only gets funkier as you head north into the Baker District, where boutiques like Decade, a source for up-and-coming designer labels, skew as hip as the nearby eateries. 
Still haven’t packed enough into your Colorado vacation? Make time to see some of the great Colorado mountain attractions — tour a ghost town near Aspen, sail above the mountains in a balloon over Breckenridge, rock out at a music festival in Telluride, check out the nightlife scene in Vail and try your luck at a casino in Black Hawk, Central City or Cripple Creek.
Why go? Possibly nerve-wracking and definitely slow-going yet breathtaking in every sense of the word, Mount Evans Scenic Byway takes you past alpine lakes and meadows, through bristlecone-pine stands and the habitats of elk and bighorn sheep; along the way, you can hike, fish, picnic and even snowshoe. The summit itself is accessible only in summer—and even then the weather can turn nasty without warning.
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. Reviewers also recommend perusing the museum's gift shop for some unique and interesting finds. If you don't make it here on your own, you'll find that the museum is a popular stop on many of the best Denver tours.

Modeled after a Kenyan nature preserve, the Denver Zoo is home to more than 4,000 animals, including tigers, black rhinos, kangaroos and orangutans. Sprawling across 80 acres of City Park, this impressive facility boasts a number of ways to view our furry, feathered and reptilian friends. Head to Predator Ridge, the recreated African savanna, to see hyenas, lions and African dogs roam, watch monkeys swing from tree branches at Primate Panorama or catch a glimpse of colorful critters like Panamanian golden frogs and green tree pythons at the Tropical Discovery center. You can also overload on cute during a visit to the nursery and take on a ride on the zoo's train and carousel.
