Take the world’s largest outdoor mineral hot springs pool (Glenwood Hot Springs), add an adventure park built on top of a mountain (Glenwood Caverns Adventure Park), sprinkle in the Roaring Fork Valley’s crimson rocks and emerald forests and you have a memorable family vacation just a few hours from Denver. The new Historic Fairy Caves Tour at Glenwood Caverns Adventure Park has sections never opened to the public before, takes 50 minutes and has only 12 stairs (perfect for families with small children than the tour of King’s Row, which has 127 steps each way). Also, don’t miss the adventure park’s thrill rides including the Cliff Hanger Roller Coaster, bungee jumping station, zipling, giant canyon swing, alpine coaster, laser tag and much more. Glenwood Hot Springs is celebrating its 125th birthday this year, so guests get in free on their birthdays. Glenwood Canyon Resort has white water rafting on the Colorado River and for an extra thrill, soar on the zipline across the river or test your mettle on a ropes course. Grab your bikes and take the paved Rio Grande Trail, which winds along the Roaring Fork River from Glenwood to Aspen. If you visit mid-week, pack a picnic and enjoy free concerts at Two Rivers Park on Wednesday. For a night out on the town, your family will love the Glenwood Vaudeville Revue dinner variety show.
I am convinced Chautauqua is Colorado’s best-kept secret and I’m amazed how few locals know about its charms. Located at the base of the Flatirons in Boulder, this National Historic Landmark has rental cottages that are surrounded on three sides with open space that includes 48 miles of hiking trails and thousands of acres of natural lands begging to be explored. On weekends in June, Theatre-Hikes Colorado will take audience members on a moderate hike amidst the scenic backdrop of Boulder Open Space while scenes from “Snow White” are performed along the way. On June 29, don’t miss the Colorado Music Festival’s Young People’s Concert, which is a is a narrated work about a cartoon score being performed at a symphony concert (tickets are $8). The historic Chautauqua Dining Hall (a tradition since 1898) has recently undergone a huge overhaul and the wraparound porch offers some of the best patio dining in Colorado. If you visit on a Saturday, be sure to also visit the Boulder’s Farmer’s Market (the largest in Colorado). Not to be forgotten are Pearl Street Mall’s restaurants, shops, people-watching and Pop Jet Fountain–they never fail to entertain.
Fort Collins is the perfect base camp for your trip, located just 35 miles from the peaks of Rocky Mountain National Park that soar to more than 13,000 feet and form the Continental Divide. The town of Estes Park sits at the eastern edge of the park. Rocky Mountain National Park covers 410 square miles and includes Longs Peak (14,255 feet high), 18 named peaks above 13,000 feet, 150 named lakes, and the highest continuously paved highway in the U.S. — Trail Ridge Road. The road is usually open from Memorial Day until early October. However, the park is open year-round and lower elevation roads are open during the winter. 
It’s always “do not disturb” mode at this quaint adults-only hideaway in Crested Butte that’s strictly 16-plus. Just a few blocks from historic Elk Avenue, Purple Mountain Bed & Breakfast has six plush rooms, an onsite day spa and an outdoor hot tub. In the winter, a free shuttle whisks you to Mt. Crested Butte for some of Colorado’s best skiing; when you’re ready for après, retire back to the house for complimentary craft beer on tap and a Ghirardelli hot chocolate bar you won’t have to share with the kids. Happy hour, indeed. Find more B&Bs in Colorado >>
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.
