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.
If the idea of floating in the air doesn’t exactly, um, float your boat, then we’ve got another awesome thing for couples to do in Colorado: hit up one of their many hot springs. One of the best is Desert Reef Hot Springs. This geothermically heated water flows from 1000 feet below ground and makes for a mineral-rich, relaxing soak with your partner.
Denver's Union Station is a two for one: it's a working public transit station and a highly praised dining and shopping center. The station was a huge success when it first opened to the public in 1881, providing railroad service until the center of the building caught fire in 1894. The architecture from the 1917 redevelopment remains and today, it's home to an Amtrak hub and a bus concourse. Located in the hip Lower Downtown neighborhood (aka LoDo), with multiple dining options and boutiques, and The Crawford Hotel, Union Station is a newfound entertainment center.
After your afternoon of devouring basically everything in sight, chances are you’ll be thirsty. So why not balance out all that food with a beer or two? Denver boasts some of Colorado’s top breweries and is famous for its craft (and historic) beers. Check out Novel Stand Brewing Company in the Baker area for a tasting session, or head north for Belgian-style brews at hip taproom Bruz Beers.
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.
Why not start your trip to Colorado by understanding the history of its capital, Denver? This city is pretty famous for its Old West feel and is full of old architecture and known for tales of gunfighters, crime families and conmen. Go and admire the frontier town atmosphere, take in views of Union Station and other landmark buildings, see what’s going on.
Start your day the right way at Denver Diner. This is a classic, classic place that’s open 24 hours a day and offers up a huge speciality breakfast (one is called “Stoner’s Delight” FYI). Suitably stuffed, roll yourself for 6 minutes to Denver Mint. Opening at 8am, this place is literally the only place that still produces American coinage. Pretty cool to see it all happening. Tip: it’s closed Fridays and the weekend.
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.
Why go? Tailgate on the stadium’s south side; stomp your feet to make “mile-high thunder”; join a chorus of 76,000 yelling “Incomplete!”: That’s the way to show your support for the Broncos. On a tour, you’ll learn such stats while visiting the Colorado Sports Hall of Fame Museum and getting a player’s-eye view of the end zone—something even non-fans get a charge out of.
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.

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?
Why go? Botanical treasure hunting sound like your new thing? Well, here you can peruse thousands of plant species from across the globe, from cacti to rainforest orchids. It’s also a cultural and educational center, regularly hosting art exhibits, plant shows, gardening classes and more. As you explore, be sure to take a breather in view of glass wizard Dale Chihuly’s Colorado, which graces the pond in the Ellipse Garden.
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.

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.

I’m sure you’re already aware of some of the things to do in Denver. As you can imagine, Denver’s proximity to nature and mountains means it offers plenty of opportunities to ski, climb, hike and enjoy many other outdoor pursuits. But for those who prefer to exert less energy while on holiday there is also a fantastic array of art galleries, museums and interesting architecture to enjoy too.
With its excellent views of the Rocky Mountains, miles of hiking trails and cinnamon-hued sandstone cliffs, Red Rocks Park is a big draw for outdoors enthusiasts. Occupying 700-some acres, this impressive park offers visitors the opportunity to experience the fascinating geographic transition between the Great Plains and the Rocky Mountains. If you only have a short amount of time here, stretch your legs along the Trading Post Trail; this nearly 1 ½-mile-long path weaves through the rust-colored buttes, making for some spectacular scenery. Before you head out, travelers recommend stopping by the visitor center, which features information on the parks history and trails.
