Why go
Fountains is the big one. The largest monastic ruins in Britain, standing almost to their full height along the River Skell, and attached to them one of the finest Georgian water gardens in England, all of it a UNESCO World Heritage Site covering around 800 acres. The Cistercians built the abbey, the Aislabie family laid out the water garden with its temples, cascades and mirror ponds in the 18th century, and the two sit together as a single landscape that has no real equal in the north. Rievaulx is more complete and more atmospheric; Fountains is bigger, grander and takes far longer. If you only do one large day out from Thirsk, this is the strongest candidate.
