Most people consider their childhood among the most carefree times of their lives. Aside from the obvious reasons—no jobs or bills to worry about—one of the key reasons is that children are free to play, imagine and embrace a fantasy world in a way that is unavailable to most adults in their day to day lives. So, it makes sense that there when choosing a vacation destination, there is great appeal to recapturing some of that youthful aura. Vacationers looking to feel like a kid again have numerous options, ranging from high-adventure to imaginative fun. Here are just a few of the best vacation destinations to make an adult feel like a kid again.

Whitney Peak Hotel – Reno, Nevada

At Reno’s Whitney Peak Hotel, adults can relive their Spiderman fantasies on the outdoor climbing wall that scales the hotel. The wall reaches a dizzying 164 feet. Those willing (and able) to reach the peak are rewarded with breathtaking views of the Sierra Nevada mountain range. For less adventurous guests, the hotel’s Basecamp rock gym provides plenty of opportunities to play, as well.

Cottage Lake Treehouse Bed and Breakfast – Woodinville, Washington

Is there anything more reminiscent of childhood than the backyard tree house? Guests looking to recapture that youthful feeling will want to visit the Cottage Lake Tree House Bed and Breakfast. “The Nest” is an ultra-cozy 144 square foot cabin perched among the trees on the banks of Cottage Lake.

Disneyland – Anaheim, California

There can’t possibly be a single reader surprised to see this one on the list, as it is probably the most recognizable symbol of youthful joie de vivre. Fans of the theme park declare that simply walking through the gates makes them feel decades younger. Visitors can while away the hours at such attractions as Small World, Peter Pan’s Flight, Pirates of the Caribbean and Dumbo to recapture the bliss of being a kid.

Travaasa – Austin, Texas

Travaasa, a 70-room sanctuary adjacent to the Balcones Canyonlands Preserve near Lake Travis, has been described as a summer camp for adults. To be sure, there are numerous activities, including zip lining, Outward Bound ropes courses, hatchet throwing, archery and much more. But it is the top-notch amenities that distinguish Travaasa from a typical camp experience. Indeed, visitors can enjoy superior dining choices, drink service at poolside cabanas, and a host of restorative spa services to help with recharging after a day of play.
