Hotel Casa del Mar, Santa Monica, USA

Take your body back in time at the Hotel Casa del Mar‘s eco-friendly Sea Wellness Spa, where signature anti-aging and hydrating skin-care therapies and new-age, full-on body de-stressers (this is California after all) will put your mind at ease and your body at rest. The property itself time-travels you back to Jazz Age elegance, with a hint of contemporary Mediterranean allure. Built as an opulent beach club in 1926, the grand Renaissance Revival architecture fuses perfectly with the needs of today’s OutThere traveller, not to mention spa-bunnies.
