How This Journalist Renewed Her Sense of Self While Helicopter-HikingHow This Journalist Renewed Her Sense Of SelfWhile Helicopter-HikingSharesI’m still glowing from having just returned from helicopter-hiking. To be dropped into a remote landscape and to hike to a hidden glacial waterfall is a heaven-on-earth experience. I’d already been heli-hiking for several days in New Zealand when I had the quintessential helicopter-hiking experience. Dion Mathewson, the pilot of the R40, the 4-passenger Robinson helicopter that he operates out of Cedar Lodge where we were staying, flew my guide and me into Boundary Creek. He swooped us down into a wild valley in the middle of nowhere, exactly like I’d imagined. With the propeller still whirling, he yelled that he’d be back about 4:30, in six hours.The low valley floor was crisscrossed with rocky streams, and steep mountain ranges rose on all sides. We slogged through a swampy, muddy marshland toward the trickle of a waterfall we could barely see. Since there are no predators in New Zealand, no bears and no snakes, no poison oak and no poison ivy, those weren’t the dangers we had to watch out for: Instead we had to be careful with each step–to lift your boot all the way up out of the muck, and then locate a safest spot to place it back down. This was mindful-hiking at its most extreme. Out in the middle of nowhere with no one around you don’t want to twist your ankle, or worse. The sight of the first graceful waterfall was worth wading through swampy marshland for a hour. “Just wait,“ said Ket, my guide. “The best is yet to come.” After inhaling that first waterfall, we headed back, and started fording the chunky creekbed. Sometimes we were wading in freezing mountain water up to our knees.For almost four hours we crossed the creekbed sixty plus times, and still we hadn’t heard or seen this next huge waterfall. I teased Ket that it didn’t exist. Ket Hazledine, 57, and a world-class mountain climber—she intended to climb the Matterhorn in Switzerland in the summer— smiled, and kept charging, sure-footed, ahead.Finally, we came around a corner and hidden by a mountain ridge–was the waterfall! Ket called it “Spectacular,” and it was. To reach such a stunning sight, untouched in nature, unnamed on a map, is a once-in-a-lifetime hiking experience. And it was available only because we got helicoptered into a totally inaccessible valley. At the top of the 70’ vertical drop there was no viewing ledge with a protective guard rail with the obligatory caution sign for tourists, because there were no tourists. And at the edge of the glacial pond there was also no green and yellow government sign like at other tracks in New Zealand because the “Spectacular” waterfall is off the charts.We positioned ourselves on rocks, wearing raincoats for protection against the spray, and just when I thought things couldn’t get any better, Ket produced a picnic lunch: a salad picked fresh from her garden, and, because I’d commented that I hadn’t been getting much shellfish in New Zealand, her husband, a fish exporter, contributed crayfish. Biting into the delicious sweet crayfish, in the spray of that waterfall—and I know this will sound corny– but I felt, I’ve died and gone to heaven.Because we’d arrived by helicopter, we didn’t have to trudge all the way back. We could lay down and relax until the helicopter came for us.It was my best day in nature—ever, and it caused me to question why when I take out my passport I’m most likely to travel to places in nature. Whether it’s trekking in Torres del Paine National Park in Chilean Patagonia, struggling across the Nature Walk marshland in Bhutan, or hiking in the mid-Atlas Mountains in Morocco, why am I also always lacing up my hiking boots, strapping on my fanny pack, and grabbing a water bottle?I suspect it’s because I grew up on Lake Washington in Seattle. It was around that gorgeous evergreen lake where stately evergreens grow down to its shoreline that I first started walking in nature, though I wouldn’t have put it that way when I was five years old.Back when kids could wander out safely by themselves, I’d leave early, carefully cross Lake Washington Boulevard, meander over to the swing sets–take a pump or two–and then I’d leave the public playground and enter my very favorite private place–the walking path in the forest that led up to the middle of the peninsula. That path, always unpopulated by other people, was my hidden, secret place. I still remember the green, musty smell and the spongy softness of the footpath. My parents and I certainly never thought little Jo Ann is getting smarter by spending her days out in nature, but recent scientific studies prove that getting outside not only does people good but makes them smarter. In an experiment at the University of Michigan, participants took memory and attention tests after strolling in a botanical garden and along city streets. The nature walk improved their results as much as 20 percent, while the sidewalk version had no effect. The research found that even looking at nature imagery had a positive effect on concentration. But we know that’s not nearly as much fun. And many of us are familiar with that well-publicized study where patients recovering from surgery were facing a brick wall versus recovering in rooms overlooking trees. The patients confronted with an expanse of brick requested narcotics at a higher rate, complained more, and spent longer in recovery than those with the leafy vista.My next travel adventure?
