Singer Olivia Newton-John and three partners founded a 25-acre retreat in the hinterlands outside Byron Bay in 2005. You can participate in daily yoga sessions designed for all levels as well as tai chi, qi gong, and Pilates. Organic cooking classes and guided bush walks through the nearby Nightcap Range are a nice study break. For an additional cost, you can customize your stay with one-on-one lessons in yoga, guided meditation, and pranayama.

From $3,865 for a five-day, yoga- focused retreat, including meals and activities. 61/(0) 2-6687-1216, gaiaretreat.com.au. Image courtesy of Gaia Retreat & Spa. This story appeared in the January-February, 2012 issue.
