The trails were built in 2008 by the Sun Valley Company. The local trail group Big Wood Backcountry Trails worked with the Sun Valley Company in designing the trails. The S.V. Co. hired the International Mountain Bicycling Association to refine the designs and build the trails.
The trails offer five miles of easy hiking and biking. They provide a nice overview of Ketchum and parts of Sun Valley, with some excellent views of Baldy gained in a number of locations. There are several scenic overlooks equipped with benches.
There are five different sections of the White Clouds Hiking and Biking Trails - Valley View, Sellgren's, Big Wood Connector, Elk and Sunrise Trails. The Valley View and Sunrise trails form the 1.7 mile Sunrise Loop, and the Valley View, Sellegren's, Elk View Trails, and the paved Trail Creek Path form the 4 mile White Clouds Loop.
There are two primary trailheads, Carol's and Earl’s. They're just off the paved Trail Creek Path, along Trail Creek Rd. Parking is available at the Sun Valley Village (Carol's Trailhead) or the S.V. Clubhouse (Earl’s Trailhead). Access by foot or bike can be had at the west end of the Big Wood Connector Trail.
