80-Year-Old Becomes Oldest Woman to Hike the Appalachian Trail

Carson City, Michigan — A journey of a thousand miles begins with a single step, but what about tackling 2,200 miles—like climbing 16 Mount Everests across 14 states?

Are you feeling overwhelmed yet? Not Betty Kellenberger. At the age of 80, she recently made history as the oldest woman to hike the entire Appalachian Trail. Now, she’s taking time to reflect on her incredible journey.

“You get to see amazing parts of our country—things you just can’t find anywhere else,” she shared, relaxing in her living room where a large hiking map laid on the rug. “The wildlife is diverse, and it’s truly beautiful.”

Kellenberger grew up on a farm in Howell, Michigan. She always dreamed of the trail that stretches over 3,000 miles from Georgia to Maine, but until now, she hadn’t committed to a six-month venture.

“I used to think, ‘It would be so cool to hike the Appalachian Trail,'” she laughed, recalling how she’d always imagined meeting Daniel Boone during her hike, even if it was just a whimsical thought.

With over 40 years in teaching—mainly English and social studies to seventh graders, along with adult evening classes—Kellenberger led a fulfilling life. She took biking trips and extended hikes in places like the Canadian Rockies and Peru. Since she was unmarried with no children, she had the freedom to explore hiking across many states without anyone saying, “You shouldn’t do that.”

“It definitely made it easier for me,” she noted.

Her journey didn’t come without challenges, especially after recovering from knee replacement surgery. Her doctor suggested she start with an easier section of the trail.

“I went to Harpers Ferry and climbed the Shenandoah Mountains, which is one of the simpler parts, and began hiking,” she explained. “I was able to do it, even with knee replacements. So I just kept at it.”

Kellenberger didn’t find the logistics and planning overly stressful either. Living in Michigan meant she couldn’t really train for the mountains, so she embraced the challenge of getting fit while on the trail.

The Appalachian Trail Conservancy reports that between 3,000 to 4,000 people attempt to hike the full trail each year, but less than 25% actually finish it.

Kellenberger first stepped onto the trail in 2024 and acknowledged that the experience was no walk in the park.

“You dream while you’re hiking,” she said with a chuckle. “You think about food, what you can remove from your pack to lighten it. It has to get up and down all those mountains.”

Enduring dehydration, a concussion from a bad fall, and even Lyme disease, she eventually reached Virginia’s southern border. But then, Hurricane Helen hit and forced her to pause her journey.

“Helen really wrecked that part of the South,” she remembered.

She managed to reroute north, but cold weather pushed her hike to the spring of 2025. As she explored New England that season, whispers emerged about her likely becoming the oldest woman to complete the trail.

Previously, the record was held by Linda Vanderloop, who finished the hike in 2024 at 74. Kellenberger didn’t initially aim for that title.

“You just have to step into it, enjoy the view, and keep moving forward,” she said. “I focus on the trail.”

Spending over 3,000 miles on foot provided her with space to reflect inwardly.

“Hiking alone allows you to sort through your thoughts; you get to see the presence of nature, stunning scenery, and meet various people,” she explained.

The end of her trek was especially emotional.

“I was overwhelmed. So many emotions as I was excited to finish,” Kellenberger said. “I looked forward to saying, ‘It’s over,’ but also felt a pang of loss for that special time on the trail.” She reflected on the quiet and peace she’d miss.

She pinpointed Maine and New Hampshire as the most challenging yet breathtaking portions of the journey. One standout memory for her was encountering a full-grown elk deep in the Maine wilderness.

With one challenge now behind her, she is preparing for her next phase of life.

“Life is a journey; it can be a series of smaller adventures or one continuous trek,” she stated. “And the greater the effort, the greater the rewards.”

Kellenberger now holds the record for the oldest woman to hike the entire Appalachian Trail. Despite her recent knee replacement and some bumps along the way, she feels it’s put her in exceptional shape.

Her next ambitions? Hiking in Iceland and possibly tackling the North Country Trail.
