1. Wolgan Valley Resort & Spa, Australia

The property: Australia’s first conservation-led luxury resort, the Wolgan Valley estate covers 4,000 acres of pristine beauty, but the actual property only occupies two per cent of that land. Comprised of 40 free-standing suites each with their own private swimming pool, the resort features a world-class spa, a hefty list of outdoor activities and first-class dining.

Eco-friendly highlights: Wolgan Valley regularly maintains eco-centric preservation programs, including restoring native vegetation in key wildlife zones. They also only use bio-degradable cleaning products, serve seasonal and regional fare in their restaurants and use 100% natural and chemical-free products in their spa.
