"More and more we're hearing from guests that they loved walking during the day and then could splurge at night," Yeaton-Masi said. "They could indulge in a great meal at night and not feel guilty about it.
"It's not like one of these big tours and have an all-you-can-eat buffet. They're locally grown, organic food that's delicious but also makes you feel good," she added.
Lauren Hefferon, owner of Ciclismo Classico, a Boston-area bicycle company, tells a similar story.
"Get fit, eat well, be with your family and be one with nature," she said of her biking vacations. "We like to take hobbyist to passion."
While such active vacations are a small part of the overall travel industry -- one or two big cruise ships might have more customers than Hefferon sees in a season -- such trips are growing in popularity.
Ciclismo Classico tries to teach its travelers not just about the area around them but also about biking and how to improve their experience, Hefferon said.
"We sincerely believe in it as an alternative form of transportation that is good for the world and good for people," she said. "We call it the cycling movement because it really is a movement."
