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.

‘A great deal of human history is told in stone alone’ writes Arianne Shahvisi, ’what is carved in stone is a hard, enduring message to the future’. Messages etched onto stone walls and tablets tell us of a past literally writ in stone, but the rocks we plunder from the Earth’s crust can also help us build a liveable future. The April issue of the AR examines stone as an architectural and urban material, digs into the political landscape it is extracted from and explores the weight of cultural and social meanings it holds. This issue features projects by IBAVI, Building Beyond Borders, Mauricio Rocha, Grafton Architects, Fernand Pouillon, Demetris Pikionis, and contributions by Steve Webb, Tomoki Kato, Nami Ogura, Nadi Abusaada, Perdita Phillips, Pierre Bidaud, and many, many more.
The front cover of the issue features Tito Mouraz’s Open Space Office series, where the lithic violence of stone creation is frozen and silent in the quarry, the detritus of human extraction feeble and tiny in comparison.
