The latest Spa & Wellness Collection by National Geographic Traveller (UK) turns its focus to one of the world’s fastest-growing wellness obsessions: longevity. From the lifestyles of centenarians to the rise of cutting-edge, science-led retreats, this issue asks what it really takes to live not just longer, but better and where in the world to begin that journey. Elsewhere, take a deep dive into the healing power of water, from riding waves to overcome trauma on Morocco’s Atlantic coast to drifting through Norway’s fjords to the soundtrack of whale song. This issue also travels to South Korea, where a booming beauty scene is drawing in visitors in pursuit of the ultimate glow, before heading to Los Angeles, where rage rooms offer a chance to smash, shout and let go — part therapy, part thrill. All this, plus a curated roundup of the latest spas and retreats to help you plan your next soul-soothing escape.
