Most visitors to the park drive over the famous Trail Ridge Road, but other roads include Fall River Road and Bear Lake Road.[95] The park is open every day of the year, weather permitting.[96] Due to the extended winter season in higher elevations, Trail Ridge Road between Many Parks Curve and the Colorado River Trailhead is closed much of the year. The road is usually open again by Memorial Day and closes in mid-October, generally after Columbus Day.[93] Fall River Road does not open until about July 4 and closes by, or in, October for vehicular traffic.[97] Snow may also fall in sufficient quantities in higher elevations to require temporary closure of the roads into July,[49][93] which is reported on the road status site.[95]

Nicknamed the “Mile-High City” because it sits exactly a mile high in altitude above sea level, Denver is Colorado’s capital and largest city. Located just east of the Rocky Mountains, Denver is a popular winter sport destination that celebrates its mining and cowboy history. The city also boasts a lively arts and culture scene with many distinguished museums, such as the Denver Art Museum, and the Denver Performing Arts Complex, one of the nation’s largest performing art centers.


The Experience: While news just broke that the old-timey train that travels along the mountainside through Pikes Peak will be closed for repairs for the rest of 2018, the nearby town of Manitou Springs should definitely stay on your bucket list. This resort town, located outside of Colorado Springs, is a true gem, complete with 1000-year-old Anasazi (the Ancestral Puebloans) cliff-dwelling ruins in the Mesa Verde National Park and a Victorian-era castle museum and tea room. Stay at the quaint Holden House bed and breakfast.

In the winter, Steamboat Springs is famous for its champagne powder; in the summertime the Yampa River Valley, Steamboat Lake and Zirkel Wilderness Area become a veritable outdoor wonderland with boat rentals, canoeing, kayaking, fishing, SUP, swimming and camping. The Coca Cola Adventure Zone at the base of Steamboat Ski Resort includes ropes course, slingshot bungee jump, climbing wall, mini-bounce, mechanical bull, human gyro and t-shirt spin art. Bring your bikes and wind along the paved four-mile Yampa River Core Trail that follows the Yampa River. Or better yet, grab a tube and cruise down the only free-flowing river in the state, meaning that nowhere along its 261 miles is it obstructed by dams or diversions (a bonus for those float trips). If you want to warm up (really hot), checkout the natural hot mineral springs at Old Town Hot Springs and Strawberry Park Natural Hot Springs. A not-to-be missed event is Steamboat Springs Pro Rodeo where contestants gather once a week to compete. Once upon a time, my daughter won the Ram Scramble and still raves about it. It’s not every day grabbing a ribbon from a sheep’s rear counts as a win!

The complex interactions of elevation, slope, exposure and regional-scale air masses determine the climate within the park,[48][49] which is noted for its extreme weather patterns.[49] A "collision of air masses" from several directions produces some of the key weather events in the region. When cold arctic air from the north meets warm moist air from the Gulf of Mexico at the Front Range, "intense, very wet snowfalls with total snow depth measured in the feet" accumulate in the park.[48]
If you love the great outdoors but also want luxurious comfort on your vacation, let the Cabins at Rams Horn Village Resort be basecamp for your Rocky Mountain Getaway. Our western-styled Cabins are the definition of Rocky Mountain comfort w/ all the modern conveniences.  Each cabin is its own private retreat from everyday cares, allowing families & friends to come & play together, & build lifelong memories.  Rams Horn Village Resort Details
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.

This 5-bedroom residence features a stunning family room with a massive gas fireplace and a professional chef’s kitchen with dining area and breakfast nook. No expense was spared on the multi-zone sound system and other electronics throughout the home. Guests can settle into the cozy library/TV room or be blown away by the mineshaft themed cinema with a state-of-the-art digital projector and 11.1-point channel sound and hundreds of first-run movies and TV – all complimentary!


Many of Arkansas’s cabins are located near areas that are popular for outdoor fun, including float and fishing streams, lakes, hiking and biking trails, national forests and state parks.

Trail Ridge Road will not open until at least Memorial Weekend but there are many amazing areas open year round in the park. Heavenly Valley is the one place in the park where sledding is allowed but you must bring your own tube or sled. Cross-country skiing is incredible with so many trails to choose from and snow shoeing is a great way to explore new areas. Stop at one of the visitor centers as you enter the park to find out what areas are open and it is always best to call ahead for weather and road conditions. Check forecasts before you go at weather.gov and insert "Trail Ridge, CO" for the location. For information about Rocky Mountain National Park call 970-586-1206 daily 8 a.m. to 4:30 p.m. (Mountain Time).

With its reputation for attracting celebrities and well-heeled travelers, Aspen is one of the world’s most famous ski resorts and one of the best places to visit in Colorado.

Most of the more than 3 million people who visit the park each year spend at least one night in one of the park’s many drive-in campgrounds. More than 350 miles of hiking trails offer visitors the chance to view the park’s wildlife, which includes hundreds of elk, bighorn sheep and deer. There is also the specially built scenic Trail Ridge Road, the highest paved road in any of the National Park in the United States.
The Cliff House at Pikes Peak is surprisingly affordable, with additional add-ons that can add a lot to your escape without breaking the bank. Add some chocolate-covered strawberries, crème brulee or an artisan cheese plate to your room for just a few dollars more. Or you can spring for a bottle or two of sparkling wine or Vista Point Chardonnay. Once you arrive, however, you’ll be blown away at the beautiful accommodations in this elegant late 1800s-style hotel with amazing mountain views, two-person spa tubs and much more. Stay at the hotel for some fine dining, venture into Manitou Springs to take in the beautiful sights or head to nearby Cripple Creek for some casino gambling.

After facing near extinction last century, the bighorn sheep population is currently thriving: there are roughly 300–400 of these striking animals in the park. Look for them at the aptly named Sheep Lakes from May through mid-August, when the bighorns descend to eat soil and obtain minerals not found in their high mountain habitat. Their visits generally occur between 9 a.m. and 3 p.m.
You’ll feel really spoiled (especially in Vail!) with complimentary WiFi,  complimentary underground valet parking, free breakfast buffet included a surprisingly hefty selection of pastries, breads, fruits, meats, cheeses, cold cereals, and eggs, as well as juice, tea, and coffee.

The hotel provides two to four hour backcountry hiking excursions led by experienced guides where guests can admire wildflowers and trees.
The park's climate is also affected by the Continental Divide, which runs northwest to southeast through the center of the park atop the high peaks. The Continental Divide creates two distinct climate patterns - one typical of the east side near Estes Park and the other associated with the Grand Lake area on the park's west side.[49] The west side of the park experiences more snow, less wind, and clear cold days during the winter months.[49]

Telluride offers the quintessential Colorado mountain town experience. Not only are its streets lined with grand Victorian buildings, but it has become a hub for adventurers, athletes, and artists of all types, nestled in an isolated box canyon, far from the chaos of modern life.

The Rockies are unbelievable. We explored the Niwot Ridge tundra plateau, speckled with wildflowers of every shape and color, looked down on the layered blue mountain ranges below, while snow-tipped peaks gazed at us from still-greater heights. I felt the elevation only in the difficulty breathing I experienced when walking from Point A to Point B - but we walked for more than three miles. Otherwise, it was the height itself that pulsed through my veins, truly on top of the world.
Dial (970) 586-1222 for a recorded message on the status of Trail Ridge Road. You may not know that our mountain makes its own weather, so it is not uncommon to have snow in July or August at the top of Trail Ridge Road. Such weather will only last for a few hours to a day, but if you are planning to cross over Trail Ridge Road, weather may hamper your travel. You also may find the road closed due to weather in early June and September/October.

The Pierre Shale formation was deposited during the Paleogene and Cretaceous periods about 70 million years ago. The region was covered by a deep sea—the Cretaceous Western Interior Seaway—which deposited massive amounts of shale on the seabed. Both the thick stratum of shale and embedded marine life fossils—including ammonites and skeletons of fish and such marine reptiles as mosasaurs, plesiosaurs, and extinct species of sea turtles, along with rare dinosaur and bird remains—were created during this time period. The area now known as Colorado was eventually transformed from being at the bottom of an ocean to dry land again, giving yield to another fossiliferous rock layer known as the Denver Formation.[58]
