The May issue of National Geographic Traveller (UK) is out now. The cover story this month focuses on the UK’s 15 national parks — from the highest peaks and deepest lochs to the most biodiverse countryside and treasured historical sites. Far from being just beautiful places to admire, they’re also adventure playgrounds, living classrooms and green spaces that bring joy, health and wellness to people nationwide. These tranquil spaces and historical sites have grown and evolved over the decades to offer hands-on action and adventure amid spectacular backdrops. We explore the best places to get involved, give back and go wild.
