The Kenya of Isak Dinesen may be a thing of the past, but a private place in the country's lush hills can still be had.

The Sanctuary at Ol Lentille (888/588-4590;; houses from $3,800 for three days), a 6,500-acre conservancy on the Laikipia Plateau, is now home to four rental villas and a spa. Each house, with its own pool, butler, and safari guide, is unique in design: the Sultan's House has low-slung Moorish sofas; the Colonel's House, campaign desks and English scroll armchairs. And Ol Lentille backs style with substance—an ownership contract grants the Masai unprecedented autonomy.
