Luckily for us, America has surprisingly affordable retreat centers where you can unwind and come home refreshed and ready for another round of life in the 21st century.
Note: Unless stated otherwise, rates are the lowest available per person, per night, meals included. Activities often cost extra.
EarthRise Center at IONS
$310, single; $275 each, double occupancy (for the weekend, with meals)
Apollo 14 astronaut Edgar Mitchell founded IONS — the Institute of Noetic Sciences (from the Greek nous, or "inner knowing") — two years after he visited the moon.
A scant 35-minute drive from San Francisco, EarthRise is IONS' retreat center. It's a place where guests are invited to contemplate, in Mitchell's words, a world in which people are "concerned with greater good for all."
"The only path to a sustainable future on Earth," he says, "is with individuals who are free, responsible, concerned with greater good for all, and willing to put those needs ahead of personal aggrandizement."
Where to sleep
The lodging is rustic but spotless, set among 194 rolling acres in the Petaluma hills. (Don't miss the uphill hike to the sweeping view from Guardian Rock.)
How to unwind
EarthRise takes its proximity to Sonoma's famous vineyards to heart. Besides offering the chance to ponder big questions, the place also has superb California haute cuisine - ginger-miso salmon with Chinese black rice with wine, anyone? (707-775-3500; noetic.org/earthrise)
