Grand Lake is arguably the biggest attraction in the town of Grand Lake, offering boating, sailing, fishing, swimming, kayaking and yachting – it even hosts a Regatta Week in early August.

Plus, as it sits near the western entrance of Rocky Mountain National Park, you’ll be steps away from one of the country’s most spectacular wildlife-filled parks too.
Loveland is called so for a reason. Romantic getaways in Colorado are blessed with vast views of Big Thompson Canyon and its inhabitants – sheep, deer, and the odd eagle. Don't miss out on Loveland Brewery, which is a bastion of Colorado's brew culture. Meanwhile, Telluride is overlooked by sky piercing peaks and retains a sense of seclusion from the outside world, making it ideal for weekend getaways in Colorado for couples. Mountain Village presents visitors with a horde of glittering attractions, while a charming "free box" is still used to exchange items.
Known as a world-class ski destination, Aspen is beautiful year around and offers activities and attractions for all ages.

Lumpy Ridge Trail leads to Paul Bunyan's Boot at about 1.5 mi (2.4 km) from the trailhead, then Gem Lake, and a further 2.2 mi (3.5 km) to Balanced Rock.[43] Black Canyon Trail intersects Cow Creek Trail, forming part of the Gem Lake loop which goes through the old McGregor Ranch valley, passing Lumpy Ridge rock formations, with a loop hike that goes into the McGraw Ranch valley.[42]


Located near the towns of Cortez and Mancos, Mesa Verde is reached by a long road that leads high up above the surrounding landscape. The drive from the highway up to the site takes about 45 minutes. Near the highway is one of the visitor centers, where you can get information on the park and road conditions before driving up. You can book a ranger-led tour of Cliff Palace when you arrive so you know what time to show up for the one-hour tour.
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. 
One of the best properties situated in Manitou Springs is Cliff House at Pikes Peak, which is perfect for your romantic getaway. Why do we call it perfect?

In around a 5 minute walk, you and your partner can explore the city all day together.
Rocky Mountain National Park is an American national park located approximately 76 mi (122 km) northwest of Denver International Airport[4] in north-central Colorado, within the Front Range of the Rocky Mountains. The park is situated between the towns of Estes Park to the east and Grand Lake to the west. The eastern and westerns slopes of the Continental Divide run directly through the center of the park with the headwaters of the Colorado River located in the park's northwestern region.[5] The main features of the park include mountains, alpine lakes and a wide variety of wildlife within various climates and environments, from wooded forests to mountain tundra.
Escape from the city with a romantic getaway just 30 minutes west of Denver to the Highland Haven Creekside Inn in Evergreen. This family-owned and operated Colorado Mountain B&B will charm you upon the moment of entering the wooded grounds.

There is a sense of history in the meticulously renovated 1800’s historic stagecoach stop that has been converted to a rustic and charming bed and breakfast. All rooms are wonderfully decorated with period antiques and there are a variety of essential and pampering amenities, including plush down comforters.

Brian eventually caught one small trout in the Moraine creek - success! - and many more in the other rivers that flowed through the park, both that afternoon and the next day. We gazed at fellow monoliths from the top of tundra trails, and spooked a red fox along a riverway. All the time, my small knitting project lay safe and secure in my pack, ready to emerge anytime we sat for more than a few moments.
Getting to Ouray is a spectacular adventure in itself, especially if you take the Million Dollar Highway that follows a 25-mile stretch of US 550 from Silverton to get here. The road’s endless twists and turns, many at the edge of sheer cliffs, brings some of the most jaw-dropping vistas in the world. As you turn each corner, the views of the soaring, jagged peaks of the San Juan Mountains seem to keep getting better – providing a pretty big clue as to why Ouray is often called the “Switzerland of America.” It’s an ideal spot for soaking in natural hot springs, gazing at countless waterfalls, and even exploring old mines.  For an in-depth knowledge of the town’s gold and silver history, head to Bachelor-Syracuse Mine where you’ll find out what it was like to be a miner back in the day. There are also lots of interesting shops on the main street, historic walking tours and even a ghost tour if you’re brave enough.
The rooms here are Euro-sexy, with dark, thick, exposed beams and spacious, mirror-lined bathrooms. The spa is one of the best in Vail Valley, with a beautiful indoor-outdoor pool, fresh spa water and tea easily accessible and multiple hot tubs, both inside and out. Sit in the bubbling, warm water with a cup of tea while snowflakes drift around you. 

Explore many miles of cycling and mountain biking trails or go white water rafting, paddling, wind-surfing and kayaking. Mesa Lake is rumored to be the best place in Colorado for trout fishing and in winter you can even go ice fishing.

Some of the highlights along the way are the towns of Silverton, Ouray, and Telluride. Set at more than 9,300 feet and surrounded by mountains, Silverton has one main street with a few shops and restaurants. In summer, it can be ridiculously busy, but in winter, most of the establishments are closed, and the place can feel like a ghost town. On the edge of town, Silverton Mountain is an old school ski "resort" with great backcountry downhill skiing for advanced skiiers. Ouray, with a sign at the main lookout calling it the "Switzerland of America," is another mountain town, known for its hot springs. If you choose to do the Skyway, you can stop in at Telluride. Known for the Telluride Ski Resort, this is one of the most beautiful mountain towns in America, with a traditional main street and gorgeous mountain scenery. You can take a free gondola up the mountain for a better look over the area.
My mind calm, the knitting absorbed any excess energy and left my senses free to absorb the stunning surroundings. Feeling no need to move, I watched the silhouettes of fish moving upstream, hummingbirds zip over my head, and a northern harrier cruise over the grassland, looking for prey. Months later, I can imagine every detail of that spot on the bank anytime I close my eyes.
Summer is the busy season in Rocky Mountain National Park, with the most popular activities being hiking, wildlife viewing, camping, fishing, horseback riding, climbing, and bouldering. Winter in the park holds its own unique beauty and attractions. Many of the roads are open year-round, although closures may occur due to weather conditions. People often come here at this time of year to snowshoe or cross-country ski, and ranger-led tours are offered in both of these sports.

It is within walking distance of the ski mountain and close to four championship golf courses and Rocky Mountain National Park.
After your fireside meal, retreat to one of the private, wooden hot tubs tucked in the middle of the woods. A hand-held stroll along the forest path to a bubbling tub overlooking the city's lights will set the perfect mood. Take it to the next level and request a night's stay in the old firehouse on the tip-top of the mountain. There's no better view — maybe anywhere in the state.

Enos Mills, the main figure behind the creation of Rocky Mountain National Park, enjoyed walking to Lily Lake from his nearby cabin. Wildflowers are common in the spring and early summer.

Other lakes in the Wild Basin include Chasm Lake, Snowbank Lake, Lion Lakes 1 and 2, Thunder Lake, Ouzel Lake, Finch Lake, Bluebird Lake, Pear Lake, and Sandbeach Lake. Many of the lakes have backcountry campsites. Waterfalls include Ouzel Falls, Trio Falls, Copeland Falls, and Calypso Cascades.[47]

Most Coloradoans know about hiking and camping in glorious Rocky Mountain National Park, biking around Lake Estes, checking out the darling shops on Elkhorn Avenue and tearing around the go-cart tracks.

Festivals abound in Estes Park during the summer–the Fishing Derby (June 1, 2013) and Wool Market (June 8-9) is free and fun for kids.

Loveland continued its expansions during the 1990’s. In 1990, Yan was contracted to install Loveland’s first fixed-grip quad. The lift serves intermediate and expert bowl terrain to the right of Chair 4. Due to increased skier numbers, in 1995, Loveland decided to enlarge the Basin lodge to its current size. This drastically increased the number of people the building could accommodate. The following year, chair 3 was replaced by a Poma quad chair, doubling the lift capacity at the Valley.


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]

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.

Vail doesn't always fit with everyone's budget, particularly if you want to spend a night during the high season. In the vicinity are a number of small towns and villages that are less well known but more affordable and also worth a visit.

The town has all kinds of quirky cafés, shops, and restaurants, and a true mountain vibe. Just up the way from here is the small town and ski resort of Breckenridge, at an altitude of 9,600 feet.
Teachers must help build the foundation for critical thinking and challenge students instead of assigning an overload of material to memorize for 1 test and forever be forgotten. Teachers themselves must be challenged as well to continue their education and modify their teaching based on this ever changing world. Hopefully these new bonus programs and raise in salaries provides satisfaction and it sparks more rigor for the staff in Denver schools.

The park may be accessed through Estes Park or via the western entrance at Grand Lake. Trail Ridge Road, also known as U.S. Route 34, connects the eastern and western sides of the park.[91] The park has a total of five visitor centers. The Alpine Visitor Center is located in the tundra environment along Trail Ridge Road, while Beaver Meadows and Fall River are both near Estes Park, with Kawuneeche in the Grand Lake area, and the Moraine Park Discovery Center near the Beaver Meadows entrance and visitor center.[9]
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]
