Under a mile away across the fields is Wilstone village and the Half Moon pub (01442 826410), a fireplace-and-oak-beams sort of place with bar meals and real ales. You can get supplies from the rather nice Meads Farm Shop (01442 828478), also in the village, by the reservoir. There's a tea room here for meals, drinks, and cakes, while the Puddingstone Distillery (01442 502033) also has its base at the farm shop site; the top product is, no surprises here, their Campfire Gin.
Other shortish pub walks from the yurt site are to the Queen's Head (01296 668368) at Long Marston, just half a mile away, or the mile to the Red Lion (01296 668366) at Marsworth — proper old country pubs, both. The more contemporary Waters Edge (01442 891708), in a lovely location on the Tring reservoirs, offers an all-day brunch and is a wine bar in the evenings. You could walk here, too, in about half an hour, and it's a really nice route out to the reservoirs. For fine dining, people swear by the rather grand King's Head (01296 668388) in Ivinghoe, a ten-minute drive away, though you'll need to book. And if you really don't know what you fancy, then a short drive to either Tring or Berkhamsted — the local market towns — gives you the choice of plenty more bars and restaurants. Tring even has its own brewery, Tring Brewery (01442 890721), where you can pop in to buy or take a tour.
