Happiest Waist-Deep In The Current On any given Saturday, you’re likely to find Gina Kelley standing in a river. The 60-year-old tried fly-fishing 4 years ago on vacation and got, well, hooked. She now drives for hours to fishing haunts or heads to her second home in Idaho, where there’s a river just out her back door. “I thought I’d just be sitting there and waiting for the pole to move. But fly-fishing is so different from that,” she says. “It took me about 2 years to really feel comfortable, because there’s so much to figure out at first. I still learn something new every time.” Then there’s the allure of her fishing spots, like this one on Silver Fork American River in California. “Fishing brings you to unbelievable places that you ordinarily might not see,” Kelley says. And if the fish aren’t “on,” there’s still something to be said for just being outside: “My days on the river are always filled with peace and beauty.” MORE: 7 Daily Habits That Are Totally Sapping Your Energy Joy On The Open Road She never mastered biking as a kid, but moving to scenic Northampton, MA, when she was 27 inspired Andrea Dre Domingue, now 34, to try again. “I’d watch people ride, and it seemed like they were flying. My friends tried to teach me, but I’d just fall,” she says. She took a beginner’s biking course in 2011 and has been rolling ever since. In 2013, Dre Domingue crossed the finish line of a 105-mile, 2-day ride in Province­town, MA, that she rode in memory of her dad, who had died of lung cancer the year before. “The last day was grueling,” she recalls, “but as soon as I saw the sign for Provincetown, I started pedaling as fast as I could.” Conquering The World’s Biggest Mountains Audrey Cadwallader has a goal to reach before she turns 60: hiking 27 of Colorado’s 53 famed 14,000-foot-elevation mountains. So far, the 58-year-old from Darien, CT, has scaled 11 of them. Cadwallader caught the climbing bug 15 years ago in Telluride, CO. “That’s where I saw Mount Wilson, my first Colorado 14er, and I had a burning desire to climb it,” she says. She reached the top in 2010, just a few months after conquering Tanzania’s Kilimanjaro. In between her Colorado expeditions, she has also reached Mount Everest base camp in Nepal; crested Mount Rainier in Washington; and, this spring, made it to the top of Antisana, Ecuador’s fourth-highest volcano, pictured here. And though she’s usually 20 years older than her climbing companions, Cadwallader keeps pace just fine. “I’m late to the game,” she says, “but so happy I found something that tests me to my limits.” MORE: 5 Common Cancer Myths You Shouldn’t Believe Anymore Five Days, Three Friends, One Mighty RiverOlder, Faster, Stronger.) To celebrate milestone birthdays last year, Marcella Wimsatt, 60; Jennifer Alvenus, 50; and Suzette Teall, 50—all operating room nurses from Gainesville, FL—headed west. Their 5-day rafting trip down the Colorado River (with guides leading the way) started with an 8-mile hike into the Grand Canyon, which the women prepped for with a yearlong training regimen developed by Alvenus, who is an avid runner. They were well prepared but had their share of challenges, including a cliff dive. “The rocks were about 25 to 30 feet high,” Teall says. “But once I saw Jennifer, who’s afraid of heights, do it, I just had to.” Going on the trip as a team also amped up their motivation to do it again. “We haven’t started planning our next trip,” says Teall, “but we know it’s going to be good.” (Learn how you can grow fitter, faster, and stronger at 50+ with the training plan in marathoner Margaret Webb’s new book,  A New Adventure Every Year Elaine Lee may be 62 years old, but (according to her) she really started living at age 40, when she met an American expat who’d dedicated his life to travel—his passport had 54 stamps from Africa alone. Inspired, Lee left her workaholic lifestyle behind to embark on her own exploits. Since then, the Berkeley, CA–based part-time lawyer and travel writer has logged more than 80 international adventures. Just a few of her accomplishments: trekking the rain forest in Costa Rica, where she is in this shot (in 2007); squeezing her way through the tunnels of a sacred cave in Belize; climbing Machu Picchu; and reaching the top of a glacier in New Zealand. She even scaled Sossusvlei in Namibia, the world’s highest and oldest sand dunes. “The view from the top was otherworldly,” Lee says. “It’s one of the few places on earth where the desert meets the ocean.” With Costa Rica’s Cloud Forest and a hiking trek in Thailand on this year’s to-do list, her passport is due for more stamps. “These experiences push the borders of your life,” Lee says. “You have more room to be who you really are.”
