When your thirst for adventure strikes, Vacations by Marriott has got you covered with our Denver vacation packages. Admire the beauty of the Mile High City by whitewater rafting, zip lining and mountain climbing, or take a casual stroll through the downtown area and admire the historic buildings to round out four amazing summer days in Denver.

Day One: It’s late morning when you hit the ground at Denver International Airport (DEN). Once in your rental car, you head into the city and check in at Renaissance Denver Downtown City Center Hotel, a historic gem that in the early 20th century housed the Colorado National Bank. You admire the series of 16 murals from iconic western muralist Allen Tupper True before enjoying a late lunch at Range. The pepperoni and jalapeno flatbread fuels you up for the evening adventure to come: stand-up paddleboarding after dark! You hit the water using adventure gear and LED paddles and – with a small group – explore like you never have before. The water and wind are calm after sunset, and you’re fascinated by the nocturnal creatures that come out at night. It all makes for a great start to your trip. As you return to the hotel for a nightcap, you’re excited about the fun summer days to come in and around this Mile High City.

Day Two: You sleep in just a bit after an enjoyable first evening in Denver and eventually gear up for some more excitement on the water this afternoon. One of the most popular outdoor activities in Colorado each summer is river rafting, so you make the drive into the beautiful mountains west of the city and eventually arrive in Glenwood Springs. You meet up at your guide’s riverfront facility and take to the water, quickly ripping through rapids with names like The Wall, Tombstone, Man Eater and Superstition. After a few miles, the water calms a bit and you learn about the amazing history of the area and the mighty Colorado River. Natural hot springs join the river, and the group stops for a soak before getting off the water and into showers. On the drive back, you stop to dine at George Restaurant & Pub in Vail. The early evening “surf and turf” specialties really hit the spot after hours on the river, and the scenery is gorgeous.

Day Three: You’ve paddled a board and helped paddle a raft in the past couple of days, and as you get up and moving this second morning in Denver, you spend a few minutes debating the merits of learning to rock climb versus riding a zip line. You eventually settle on the zip lines and decide rock climbing can wait until next time. So it’s off to Colorado's Front Range - the gateway to Rocky Mountain National Park - to zip through the trees and enjoy some more of that fresh mountain air. You gear up and fly through trees and over meadows as you take in the spectacular views and feel the adrenaline surge through your bodies. The entire course spans some 6,000 feet and provides another amazing experience. Back in town a little later, you stop by Mile High Spirits for your own “happy hour” and share some pictures with friends at home while sampling spirits in one of the most popular tasting rooms in Denver. What a day!

Day Four: Your visit to Denver is nearing its conclusion, but before your flight home later this afternoon, a visit to the 16th Street Mall is in order. Less than a five-minute walk from the hotel, the pedestrian promenade is the place where residents and visitors alike get together for shopping, dining, movies and more. You stroll down the tree-lined street and browse through some of the shops before taking a seat near a fountain to people-watch for a few minutes. Eventually you grab a patio table at Appaloosa Grill, where the crab and grapefruit salad seems to perfectly complement the outdoor scene on a sunny summer afternoon. More than just a winter gateway to the Rockies and world-famous ski destinations, Denver and its surrounding area is full of warm-weather adventure and abundant charm, and as you board the plane, you can’t stop thinking about those rock climbing lessons. They’ll still be waiting when you return.
