The National Trust's best campsites Clumber Park, Nottinghamshire Best for: Mongolian yurts The traditional Mongolian yurt at Clumber Park is 22ft wide and sleeps up to 8 people. Also available for campers is a 4-mile walk around the serpentine lake with its 18th Century bridge, bicycles for hire to traverse the many bike tracks and boat and tractor rides. Dolaucothi Gold Mine, Carmarthenshire Best for: sea trout fishing The River Cothi is also one of the best spots in the world for sewin (sea trout) fishing and it is right next door to this wooded site. Also close by are gold mines - so if you've had no luck with your rod, you can try your hand at gold panning instead, in a complex of pits left by the Romans nearly 2,000 years ago. Highertown Farm Campsite, Cornwall Best for: beach This eco-friendly campsite is a short walk from a secluded beach hidden within an impressive coastal landscape. Gribbin Head across the coast, is famed for its association with Daphne du Maurier and is walking distance away. The towns of Polperro, Fowey and Looe are also nearby. Downhouse Farm, Dorset Best for: fossil hunting Only 200 yards from the beach, Downhouse Farm sits on the Jurassic coastline, which traces almost 185 million years of the earth's history. Nearby attractions also include Brownsea Island - home to some of the rarest wildlife in England - and Corfe Castle. Upper Booth Farm, Derbyshire Best for: walking In the central Peak District, here you can pitch up on a working hill-farm with access to some great walks from your tent. There are options for both leisurely strolls and more challenging hikes. The Longshaw Estate, with views over the Derwent Valley, is nearby. Etherley Farm, Surrey Best for: croquet At the foot of Leith Hill, beneath an 18th-century gothic tower that crowns the highest point in south-east England, this is a small campsite near Polesden Lacey, a home where campers can experience life in the roaring Twenties, with a croquet lawn in the garden and collected objects from the lady of the house's many parties. Houghton Mill, Cambridgeshire Best for: wildlife Great for anyone wanting to see voles, dragonflies and butterflies scampering around tall grasses by the side of the River Ouse, close to its last working mill. Set over five storeys, the mill includes lots of hands-on exhibits for all the family and there's the chance to buy wheat which is occasionally still ground. Wasdale Head, Cumbria Best for: hiking Set under rugged Scafell Pike, England's highest mountain, this remote site has views that stretch out over wild Wastwater lake. Campers are not too far from home comforts however, as new camping pods have been installed that keep cosy and dry in even the wettest Lakeland weather. Nostell Priory Holiday Park, Yorkshire Best for: family fun A new adventure playground will amuse children at this site, as if running free in 300 acres of parkland were not already enough. Other activities include lakeside walks, exploring the priory grounds and croquet on the lawn.
