The Bivouac
Yorkshire's newest posh site (it opened in April) is a hit with Richard. Among the accommodation options are eight yurts equipped, unusually, with running water. "The site has an impressive commitment to sustainability, including a vast wood-chip boiler to supply heating and hot water, and a café that serves delicious local food." For ultimate decadence, book a lomi lomi massage.
High Knowle Farm, Knowle Lane, Masham (thebivouac.co.uk). Yurts from £240 for four nights for up to five
