^ Montana State University states in their profile of Rocky Mountain National Park that there has been an increase of 2.5 °F (1.4 °C) in the average park temperature over "the past century" (charts show the period from about 1895-2010).[48] The National Park Service site states that the increase has been 3.4 °F (1.9 °C) over "the last century" (chart shows the period from about 1905-2010).[52]
_{In the shadow of Great Sand Dunes National Park and Pre­serve, the quirky town of Hooper sits atop a natural artesian hot spring, with water flowing year-round into the family-friendly Sand Dunes Pool.

Colorado’s only Relais & Chateaux dude ranch offers a seemingly endless list of things to do, but creature comforts abound, too — from the elegant Western accommodations nestled in aspen groves to the haute mountain cuisine that has been hailed by Bon Appétit and Gourmet. In addition to adult weeks offered August through October, Home Ranch in Clark also hosts yoga and horse­back-riding retreats, perfect for girlfriend getaways.
Estes Park is one of the most beautiful mountain retreats in all of Colorado — and we’re not just saying that because they’re our neighbors! OutThere Colorado named the village on their list of the 10 Most Beautiful Places to Spend a Weekend in Colorado. It was chosen for its proximity to Rocky Mountain National Park and the stunning views from Estes Park Aerial Tramway.

The park contains a network of trails that range from easy, paved paths suitable for all visitors including those with disabilities, to strenuous mountain trails for experienced, conditioned hikers as well as off-trail routes for backcountry hikes. Most trails are for summer use only, since at other times of the year many trails are not safe due to weather conditions.[82] The park provides dozens of designated backcountry campsites and horseback riding is permitted on most trails.[83] Llamas and other pack animals are also allowed on most of the trails.[84]
For dinner, award-winning Trecento Quindici simply can't be beat. Food is mouthwatering and service is impressive; you can even expect a "crumber" to keep the crumbs from building up on the white tablecloths. The food here is exquisite. It's contemporary, handmade Italian (can you say "Lady and the Tramp?"). Dine in tall, dramatic chairs and feel like royalty.
Our last (but definitely not least!) romantic hotel in Colorado is the Leroux Creek Inn & Vineyards. This secluded B&B is surrounded by vineyards and the valleys and mesas of the Grand Mesa located on 54 acres.  Sip their wine while gazing from the Leroux Creek Inn’s flower-bedecked patio onto their vineyards. Near the small town of Hotchkiss, the acreage also includes a creek, dry arroyos, grass pastures, sagebrush, and trees.
Dinosaur National Monument, in northwest Colorado, combines dramatic scenery with natural and cultural history to create one of Colorado's most interesting sites. Dinosaur remains embedded in exposed rock walls reveal evidence of the giants that once roamed these areas. Petroglyphs offer insight into the cultures and people that lived here long ago, and surrounding it all are cliff walls and the Green and Yampa Rivers snaking through the otherwise dry landscape.
Baker Pass crosses the Continental Divide through the Never Summer Mountains and into the Michigan River drainage to the west of Mount Nimbus[36]—a drainage that feeds streams and rivers that drain into the Gulf of Mexico.[28] Other mountain passes are La Poudre Pass and Thunder Pass, which was once used by stage coaches and is a route to Michigan Lakes. Little Yellowstone has geological features similar to the Grand Canyon of the Yellowstone. The Green Mountain trail once was a wagon road used to haul hay from Big Meadows. Flattop Mountain, which can be accessed from the eastern and western sides of the park, is near Green Mountain. Shadow Mountain Lookout—a wildfire observation tower—is on the National Register of Historic Places.[36] Paradise Park Natural Area is an essentially hidden and protected wild area with no maintained trails penetrating it.[39]
That was not my intention. We planned a trip from Florida to the Rocky Mountains of Colorado for one of my freelance writing projects, and originally scheduled a day in Denver (at 5,280 feet in elevation) to acclimate. Frontier Airlines had a different idea. I heard alternatively that our plane had a mechanical issue, that weather in the Midwest grounded the flight, and that the crew went on strike. Regardless, the airline cancelled our original flight.
The Experience: Denver is the perfect urban adventure for anyone who likes midsize cities. It's easy to navigate and manage and doesn't feel at all claustrophobic, but offers endless cultural excursions, gourmet dining experiences, and a fun nightlife you'd expect from large cities. Make sure you visit the Denver Art Museum, check out the breweries in the RiNo neighborhood, and stay at the Crawford Hotel, which is in the old Denver Union Station. For a boutique hotel, stay at The Maven Hotel.
