The Resort at Paws Up, Montana
As well as being a cattle ranch, Paws Up caters for 28 luxurious timber houses that sleep between four and eight. Guests can better appreciate the wilderness from the two dozen luxury tents, scattered in woodland or on the banks of the Blackfoot river. Inside are proper beds and en suite bathrooms, safari-style décor (antler light fittings, dark wood furniture and rattan mats), and each opens on to a private deck.

Wandawega Lake Resort, Wisconsin
Opened in the 1920s, Wandawega Lake Resort had fallen into disrepair until it was restored to its former glory by current owners David and Tereasa. It now offers an idealised take on the camping experience: halcyon days camped between woodland and sun-dappled lake; Scout tents filled with vintage books, plaid blankets and hurricane lamps; bonfire pits, tennis courts and more. There are also lakeside cottages, deluxe log cabins and a farmhouse-chic guest house.
Wandawega Lake Resort, Elkhorn, Wisconsin (001 312 282 4693; wandawega.com). Cabins from $200 (£122), tents from $100 (£61), room only.
El Capitan Canyon, California
El Capitan Canyon campground overlooks the Californian surf at El Capitan beach. A short stroll into the cedar and sycamore groves brings you to the camp's wood cabins and safari-style tents. Despite the campground's claim that it has "purposely avoided attempting to duplicate the conveniences of home", you'll find willow-frame four-poster beds and downy duvets inside the tents. Firepits and barbecue kits invite you to get back to nature while free summer concerts and complimentary use of bikes add to the outdoor appeal.
