With more than 2,000 caves and potholes and more than 400km of surveyed passages, the Yorkshire cave system is one of the most extensive in the country and beginners and experienced cavers will be in their element. The Ease Gill system, which extends into Cumbria and Lancashire, is a complex series of passages more than 70km in length.
Gaping Gill is a 105m-deep pothole whose main chamber is big enough to contain St. Paul's Cathedral. The North York Moors, and The North York Moors National Park are a scenic backdrop to the coastline. Heather moors, rolling hills and picture-perfect country towns are best explored by navigating the 2,300km of paths and tracks by bike, by foot, even by ATV (all terrain vehicle). For a thrilling ride head to Dalby Forest, England's largest mountain bike trail centre – it has 50 miles of trails, with woodland cycling for every ability.
Rocksports are big in Yorkshire, with the limestone cliffs of the Yorkshire Dales providing some of the best sport climbing to be found anywhere in Europe. Malham Cove, Gordale Scar and Kilnsey Crag are hot spots where experts can show off their skills. Surfing is popular around Scarborough and Cayton Bay with autumn being the best time for a dip. If it's white water that you're there's plenty of that too, the River Washburn is a top spot.
