Glacial Basin was the site of a resort run by Abner and Alberta Sprague, after whom Sprague Lake is named. The lake is a shallow body of water that was created when the Spragues dammed Boulder Brook to create a fish pond. Sprague Lake is a popular place for birdwatching, hiking and viewing the mountain peaks, along with camping at the Glacier Basin campground.[46]
Following pickup from Denver Union Station, travel by comfortable, air-conditioned coach into the famous Rocky Mountains, or Rockies for short. Your knowledgeable driver delves into the powerful geologic forces that created this stunning mountain range as you drive over Berthoud Pass, 11,314 feet (3,448 meters) above sea level, crossing the Continental Divide. Continue to admire the rugged Rockies as you descend curving, tree-lined roads. You will drive through Winter Park, a small ski resort town on the western slope of the Continental Divide with fun family activities throughout the year. Then you will head to the next town, Grand Lake. Enjoy lunch at an outdoor cafe with fantastic views of the town's namesake, the largest and deepest natural lake in Colorado. Your tour culminates at Rocky Mountain National Park, a 265,000-acre (107,240-hectare) park with 150 lakes and dozens of lofty mountain peaks. Keep your eyes open for elk, bighorn sheep, moose and black bears as you make your way through the park. Drive along Trail Ridge Road, ascending more than 12,000 feet (3,658 meters) above sea level. Along the way, pause at overlooks for incredible photo ops of peaks, valleys and rushing streams. Enjoy more scenic mountain roads on your return journey, and conclude your 10-hour day trip in central Denver.
More than 3,000 elk, 800 bighorn sheep and herds of mule deer and moose live in the park. For the best photography lighting and opportunities to spot massive bugling elk, head to Moraine Park just after sunrise. View bighorn sheep at Sheep Lakes May through mid-August and catch a glimpse of RMNP’s ever-elusive moose population along the Colorado River in the Kawuneeche Valley on the park's west side.
The Western Slope has plenty of charms, including being a dinosaur mecca with plenty of hands-on science, and is the heart of Colorado’s agricultural region. At the Museum of Western Colorado’s Dinosaur Journey, visitors can get up close and personal with dinosaur skeletons, a working paleontology lab and realistic robotic dinosaurs. Dedicated to “putting science in the hands of kids,” the Western Colorado Math and Science Center features interactive exhibits in biology, physics, earth and space science, and electronics. From June through October, orchards are laden with some of the sweetest harvests around: cherries, grapes, apples, plums, pears, apricots and peaches. Take an orchard tour or check out the myriad of roadside stands selling fresh produce, jams and ciders. For great biking or strolling, the Colorado Riverfront Trail winds for more than 18 miles through the city of Grand Junction’s picnic grounds, botanical garden, protected wetlands and fishing pier. Buy one/get one free passes are available for six major attractions from the Grand Junction Visitors Center. This “Map to Adventure” includes Dinosaur Journey, Museum of the West, Cross Orchards, the John McConnell Math & Science Center, The Art Center and the Western Colorado Botanical Gardens.
Tucked deep in the San Juan Mountains in southwestern Colorado, this carefully restored 19th-century ghost town and natural spa is surprisingly well appointed. The rugged, old-timey building exteriors hide high-end features such as cathedral ceilings, air conditioning, and gas fireplaces. Dolores has four parks and a peaceful bike trail that takes peddlers along the tumultuous Dolores River. You can enjoy hands-on exhibits and a nature hike at the Anasazi Heritage Center, or explore an exact replica of the original narrow-gauge rail car, the Galloping Goose. Share a romantic meal with tasty cocktails at Sophia’s Bistro.
As of 2010, the preceding one hundred years of records indicated an increase in the average annual temperature of approximately 3 °F (1.7 °C).[48][52][a] The average low temperature has increased more than the average high temperature during the same time period.[48] As a result of the temperature increase, snow is melting from the mountains earlier in the year, leading to drier summers and probably to an earlier, longer fire season.[48] Since the 1990s, mountain pine beetles have reproduced more rapidly and have not died off at their previous mortality rate during the winter months. Consequently, the increased beetle population has led to an increased rate of tree mortality in the park.[53]
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]
Rising from 7,800 feet to 12,000 – even 14,000 feet in some places – RMNP is a high-elevation park and if you don't give yourself time to adjust to the thinner atmosphere and lower oxygen levels, you could run the risk of getting the headaches, nausea and disorientation characteristic of altitude sickness. Along with taking a day or so to acclimate to the high altitude, you should make sure to consume plenty of water and food to ward off symptoms. 
While it is possible to travel through Rocky Mountain National Park and not catch sight of any wildlife, we venture to say that is an unlikely experience. From everyday sightings of chipmunks and mule deer to the moving experience of viewing elk in rut (the mating season), the animals in the park let you know that you are part of something truly wild. Some of these critters are harder to spot than others - they might camouflage themselves in the trees or hide in the underbrush - but look closely and you may have an encounter unlike any other.
