A few miles off the coast of Athens sits Silver Island Yoga, named for the silver look of the shimmering olive tree leaves on this 60-acre working olive farm. Run by sisters Lissa and Claire Christie, whose family has owned the small island for 50 years, the retreat shares the lush property with little else than a church and a lighthouse. The resort's five rooms are divided between the main house and the villa, two traditional white houses with blue shutters that can accommodate just ten guests. New guests arrive to the pebbled beaches by boat, and spend Sunday through Saturday participating in two-hour dawn and sunset yoga sessions overlooking the ocean, taught by a revolving door of diverse instructors. The Christies encourage guests to take advantage of the picturesque Mediterranean seascape with kayaking and snorkeling, hammocks for unwinding, and art supplies. The resort also provides vegetarian meals harvested sustainably from local farms, served communally beneath a large palm tree.
