Located just a few miles to the northwest of Denver, Boulder is a college town nestled against the foothills of the Rocky Mountains. Boulder’s inhabitants are best known for their healthy lifestyles, and outdoor activities are plentiful in and around the city. Boulder Creek cuts straight through the town and is lined with walking and biking trails. The four-block pedestrian-friendly Pearl Street Mall features outdoor performers in all but the most inclement weather. A drive up Baseline Road on Flagstaff Mountains rewards visitors with spectacular views, and there are picnic areas and hiking trails to enjoy at the summit as well.
Just a 5-minute stroll from downtown Estes Park, Fall River Village offers 66 luxury accommodations, including 60 two bedroom and two bathroom condos, a honeymoon suite, four three bedroom and four bathroom townhomes and a four bedroom townhome with panoramic views of the Continental Divide. Property amenities include a heated, outdoor pool, year-round, outdoor hot tubs, a community room, fire pit and grill areas as well as an outdoor recreation area with yard games and a hammock.
With many peaks and granite rock formations, there are lots of rock climbing opportunities. Some favorite climbs include the aptly-named Lumpy Ridge and Longs Peak. Whether you prefer bouldering, mountaineering, rock climbing, or ice climbing, the park has something for climbers of all levels. In the winter, opportunities for snowshoeing, skiing, and sledding draw all levels of explorers. If you're in the western part of the park, visit Grand Lake. This breathtaking lake is the state's largest natural body of water, promising scenic views and plenty of outdoor fun. 
Precambrian metamorphic rock formed the core of the North American continent during the Precambrian eon 4.5–1 billion years ago. During the Paleozoic era, western North America was submerged beneath a shallow sea, with a seabed composed of limestone and dolomite deposits many kilometers thick.[54] Pikes Peak granite formed during the late Precambrian eon, continuing well into the Paleozoic era, when mass quantities of molten rock flowed, amalgamated, and formed the continents about 1 billion–300 million years ago. Concurrently, in the period from 500–300 million years ago, the region began to sink while lime and mud sediments were deposited in the vacated space. Eroded granite produced sand particles that formed strata—layers of sediment—in the sinking basin.[55]
The Experience: If Aspen isn't quite your mountain town scene, head to Vail instead. It's equally as idyllic (it was modeled after European mountain resorts), pedestrian-friendly, and lovely, but the town itself is more of a square in a village with a small collection of boutiques and restaurants for visitors. Ride up and down the gondolas for mountain views in every direction and ski the unique back bowls. It's also closer to Denver, making it easier to get to and, therefore, a little more crowded during peak seasons.
The city of Vail was built to accommodate the Vail Ski Resort, which is the largest single-mountain ski resort in the country. With 193 marked skiing trails, Vail is one of the nation’s most popular ski resorts as well. The Tyrolean-style village is nearly as well visited during the summer. Nearby streams and lakes stocked with fish make Vail an angler’s dream, and opportunities for river rafting abound. Horseback riding, mountain biking, golf and hiking are other popular warm-weather activities.
Thanks to a wide variety of things to do and places to see, Boulder is arguably one of the best weekend getaways in Colorado—if not the whole Western United States! This college town (home to University of Colorado Boulder) has it all: hike the Flatirons or Chautauqua Park in the morning, tour the Celestial Seasonings Tea Factory and Leanin’ Tree gallery in the afternoon, and then head to Pearl Street for shopping, drinking, and dining at night—and get around on the Boulder Creek Path in between. A Boulder bike tour helps you fit in even more sightseeing, perfect for a quick itinerary.
At about 68 million years ago, the Front Range began to rise again due to the Laramide orogeny in the west.[58][59] During the Cenozoic era, block uplift formed the present Rocky Mountains. The geologic composition of Rocky Mountain National Park was also affected by deformation and erosion during that era. The uplift disrupted the older drainage patterns and created the present drainage patterns.[60]
