Helicopter pioneer Stanley Hiller Jr. founded the Hiller Aviation Museum with the future in mind, using history to inspire future generations to explore and create. He had firsthand proof of the innovative abilities of youth—his design for the first successful coaxial helicopter landed at age 15.

In the museum he established in 1998, 53,000 square feet of exhibits let visitors of all ages discover more than 40 aircraft without the dangers of encountering them in the wild. A narrated walking tour leads the way through them, tracing the history of flight from its humble beginnings in village jumping contests to today's supersonic jets. Fixed-wing and rotary aircraft designed by Hiller and others rest throughout the huge, bright space, while weekends beckon would-be pilots into a flight simulator equipped with huge monitors of bay views and realistic yokes, throttles, and pedals.

Yoga Belly's misty-blue studio with its inviting wicker armchairs envelops students in a soothing ambiance to match its relaxing yoga schedule. A stable of savvy instructors guides stretchers of all stripes amid heated classrooms stoked to warm the muscles, enticing stubborn sweat and room-temperature leftovers from the body. Yoga Belly's sprawling studio affords each stretcher enough space to sprawl atop rich, chocolate-colored wooden floors. Yogis can bring their own mats and towels, or can rent them for class or makeshift-fort duty.

Emerald Hills Golf Course strings together nine par 3 holes that test short-game proficiency as players use shorter irons to propel their golf balls through course's frequent elevation changes. The sixth hole presents opportunities for holes-in-one with a downhill tee shot of just 120 yards into a bowl-shaped green, easily replicated from a backyard deck into an inflatable swimming pool.

Golfers hoping to shave strokes off their scores can work under the tutelage of the course's certified teaching professional, Chris Raddie. Players can then practice Chris's corrective advice after a lesson or before a round on the two practice greens or midsize practice cage, which can double as a penalty box for prevaricating scorekeepers.

Course at a Glance:

• 9-hole, par 27 course
• Total length of 1,156 yards from the back tees
• Course rating of 54.2 from the back tees
