Sheffield The Outdoor City

Sheffield is The Outdoor City:

The historic and spiritual home of the Peak National Park, UK climbing; unrivalled downhill mountain biking; infamous road cycling and a hive of activity for kayakers, cavers , walkers and runners of all ability. We recognise that this is not only part of our local character, but it also is about community, health and wellbeing, and we are incredibly lucky to have this resource as part of our urban landscape.

It has not all happened by design – it is partly the result of the city’s unique geography (of which 1/3 sits in the Peak District National Park) but also the amazing clubs, facilities and communities and people who live there because of it. On top of this there is a thriving cultural scene around music, art and beer, which means the nights are as much fun as the days.
