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.
Boulder – Boulder is Denver’s neighbor city, well-known for its liberal-minded and affluent population. The town itself is smaller and pretty quiet compared to Denver but is much closer to the Rocky Mountains. Some of the best attractions near Denver are located around Boulder including the Flatirons, Eldorado Canyon, and Isabelle Lake. Visit Boulder for a chance to get outdoors and play around a bit.
Colorado is home to over 80 wineries spread out across the state, including the highest altitude vineyards in the US! Visits to the wine country are normally a two or three-day affair and a pleasant experience. But, if you don’t have the time to head out of town on your Denver itinerary, then you’ll be pleased to know that many of the wineries have cellar doors right in the city!
Denverites don't hesitate to praise their beloved Washington Park, comparing it to Boston Common or New York City's Central Park. You can get to Washington Park from the downtown area by hopping on the E light rail line.  You are welcome to visit Washington Park at any time of day or night, and there's no entry fee; however, different facilities within the park adhere to their own hours of operation and may charge admission. For more information, visit the Washington Park website.
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.
If hiking, ziplining, rock climbing and white water rafting constitute way too outdoors-y stuff for you to be getting up to in Colorado, that’s ok. There’s plenty of ways to see the true scale of the scenery of this state without even getting out of your car. The Loveland Pass is one of those ways. Passing through the Rocky Mountains at 11,990 feet above sea level, the views from here are going to be pretty spectacular. Some say it’s the highest mountain road that’s open even when there are snowy conditions. It can be pretty hairy if you drive it during snow season (you will need snow chains!) and even in spring and summer there’s still a risk of altitude sickness. If you want adventurous stuff to do in Colorado, note this one down!

Even if you hate the sound of excess change rattling around your pockets, you'll find a tour of the Denver branch of the United States Mint to be an interesting way to spend an hour or so. Having opened in 1863, its purpose was to transform the Gold Rush's findings into coinage. Today, the U.S. Mint in Denver can produce up to 50 million coins a day.

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? Peep iconic modernist furnishings (see: Irving Harper’s marshmallow sofa and Pierre Paulin’s ribbon chair) and exquisite Art Nouveau and Art Deco housewares. Located in the studio of its late namesake, Vance Kirkland, the collection is displayed salon-style—which means that you’re surrounded on all sides by irreplaceable objet d'art as you wander through the galleries. (For better or worse, children under 13 are not admitted.)
