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.

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
• Course slope of 88 from the back tees
• Two sets of tees per hole

Developed by acclaimed yogi B.K.S. Iyengar, Iyengar yoga emphasizes precise body alignment, which increases stability, concentration, and the mind’s ability to focus inward. Yoga Fitness codirectors Linda Bostrom and Jito Yumibe know the discipline inside and out—both studied with the Iyengars in India and received Iyengar certification in 1988. Their team of expert instructors teaches poses to students of all levels, from guests with no yoga background to advanced pupils with command of every pose. At sessions catered to yogis aged 50 and up, teachers leisurely move through Iyengar poses before bending into walkers to help students back to their cars. The facility accommodates all visitors with changing rooms, props, and mats, though students can bring their own. Along with classes, Yoga Fitness hosts workshops and 200- and 500-hour registered yoga trainings with certified Iyengar teacher Marla Apt.
