Set in 600 acres of mountains, orange groves and mature gardens, California’s Golden Door is the original Hollywood wellness retreat. For 60 years, it has played host to the stars, from Elizabeth Taylor and Debbie Reynolds to Nicole Kidman and Julia Roberts. Following its acquisition in 2012 by philanthropist Joanne Conway – wife of Carlyle Group founder Bill Conway – it underwent a root-and-branch makeover, with Conway also doubling the estate’s footprint. Today, Golden Door offers more than 80 classes, from yoga and mindfulness to fencing with Olympic champion Dmitry Guy and Bollywood dancing, while the acclaimed chef Greg Frey Jr creates farm-to-table menus with ingredients grown in the retreat’s biointensive gardens and 3,000sq ft glasshouse. Golden Door (from $9,450 per week) donates all net profits to charities supporting survivors of abuse, such as the New York Society for the Prevention of Cruelty to Children and the I Have a Dream Foundation.
