Brian and I descended back to ~7,000 feet for dinner in a small-town Indian restaurant in Nederland, Colorado, west of Boulder. By then, both our heads ached like a bad hangover, and my lungs literally burned when I tried to inhale anything but shallow breaths. Add generalized joint pain, and I had a full-blown case of altitude sickness. Given that I am a noted hypochondriac, I expected the worst.

^{An alpine village peppered with an array of modern resorts, Beaver Creek is the perfect weekend getaway destination. A laid-back ambiance of unhurried travelers, here visitors can get away from it all with the area’s world-class skiing and resort amenities. With gorgeous Rocky Mountain views, Beaver Creek is located in the Vail Valley and offers plenty of activities to fill a weekend itinerary. Many people come to try their hand at the 1,815 acres of skiable slopes, catering to both novice and experts alike. The area has plenty of other things to do, however, as visitors can take in a show at the Vilar Performing Arts Center, or indulge in anything from golf courses to pampering spas, shops and restaurants, with the city even home to a large outdoor ice rink in its city center.}

We love Colorado Springs staples like the Garden of the Gods Park, The Pike’s Peak Cog Railway, U.S. Olympic Training Center and Manitou Cliff Dwellings but the big news this summer is Cheyenne Mountain Zoo’s new $13.5 million exhibit Encounter Africa. Highlights include an amphitheater that will allow guests to see elephant training, enrichment and husbandry, a new exhibit for the African lion pride and a “Skybridge” that will take guests from the exhibit to the barn, enabling them to see the elephants from above. www.cmzoo.org. For a thrill, check out the Cave of the Winds’ Wind Walker Challenge Ropes Course that is located on the rim of a 600-foot drop into Williams Canyon.  Colorado Wolf Adventures have teamed up to host “Up Close with the Wolves” this summer. The new 4,400 square-foot Florissant Fossil Beds National Monument’s Visitor Center offers more fossils on display and interactive exhibits.  If a train ride is on your bucket list, the South side of the Royal Gorge Bridge and Park takes on a new look with the addition of Pinon Ridge Play-Land, a 2,000-square foot playground built specifically to blend into the natural surroundings.

The montane ecosystem is at the lowest elevations in the park, between 5,600 to 9,500 feet (1,700 to 2,900 m), where the slopes and large meadow valleys support the widest range of plant and animal life,[69][70] including montane forests, grasslands, and shrublands. The area has meandering rivers[70] and during the summer, wildflowers grow in the open meadows. Ponderosa pine trees, grass, shrubs and herbs live on dry, south-facing slopes. North-facing slopes retain moisture better than those that face south. The soil better supports dense populations of trees, like Douglas fir, lodgepole pine, and ponderosa pine. There are also occasional Engelmann spruce and blue spruce trees. Quaking aspens thrive in high-moisture montane soils. Other water-loving small trees like willows, grey alder, and water birch may be found along streams or lakeshores. Water-logged soil in flat montane valleys may be unable to support growth of evergreen forests.[70] The following areas are part of the montane ecosystem: Moraine Park, Horseshoe Park, Kawuneeche Valley, and Upper Beaver Meadows.[70]
The Experience: Everywhere you look in Aspen, the views will take your breath away, especially if you stay at the historic Hotel Jerome. It's the ultimate mountain resort town every time of year, with world-class shopping, delicious food spots, and, as we mentioned, gorgeous scenery. Ski in Snowmass or Highland Bowl. In the summer, try to plan your trip to attend the wine and food festival or the annual jazz festival. Catch a show at Belly Up, party on the mountain at Cloud Nine, eat at Matsuhisa, or cross-country ski to dinner at the remote Pine Creek Lodge.
Situated in Southern Colorado, the Great Sand Dunes National Park is an impressive sight. Shaped by winds blowing from and against the nearby Sangre de Cristo Mountains, the piles of sand climb to more than 750 feet (230 meters), making them the tallest dunes in North America. Sand-boarding, skiing and sledding on the dunes are the park’s most popular activities, and there are medium-size slopes to slide on located near the main parking area. A longer hike to the north brings thrill seekers to a 300-foot (90 meter) slope that tumbles onto into Medano Creek.
The park is home to some 2,000 to 3,000 elk in summer, and between 800 and 1,000 elk spend the winter within its boundaries. Because of lack of predation, the National Park Service culls around 50 elk each winter. Overgrazing by elk has become a major problem in the park's riparian areas, so much so that the NPS fences them out of many critical wetland habitats to let willows and aspens grow. The program seems to be working, as the deciduous wetland plants thrive within the fencing. Many people think the elk herd is too large, but are reluctant to reintroduce predators because of its proximity to large human populations and ranches.[76]
Chapin Pass trail traverses a dense forest to beautiful views of the Chapin Creek valley, proceeding onward above timberline to the western flank of Mount Chapin. Tundra Communities Trail, accessible from Trail Ridge Road, is a hike offering tundra views and alpine wildflowers. Other trails are Tombstone Ridge and Ute Trail, which starts at the tundra and is mostly downhill from Ute Crossing to Upper Beaver Meadows, with one backcountry camping site. Cache La Poudre River trail begins north of Poudre Lake on the west side of the valley near Milner Pass and heads downward toward the Mummy Pass trail junction. Lake Irene is a recreation and picnic area.[40]
