Discovery Bay Golf Course occupies a distinctive setting on Lantau Island in Hong Kong's New Territories, accessible primarily by ferry from the main urban areas. The Jade-Ruby routing represents one of two eighteen-hole courses designed by Robert Trent Jones, Jr. at this facility, which opened in the 1980s as part of the broader Discovery Bay residential and resort development. Jones's design work here reflects his approach to creating playable resort golf within Hong Kong's challenging topography and subtropical climate. The course navigates rolling terrain characteristic of Lantau Island's coastal landscape, with elevation changes that provide variety in shot-making and strategic options. Jones incorporated natural contours into the routing, and the layout features the designer's typical emphasis on risk-reward opportunities and multiple teeing grounds to accommodate different skill levels. Water hazards and bunkering define key decision points throughout the round, while the subtropical vegetation frames holes and influences wind patterns. Discovery Bay Golf Course serves primarily as a members' club with limited public access, catering to Hong Kong's expatriate and local golfing communities. The facility's island location creates a resort-like atmosphere distinct from the city's density, though the courses remain relatively accessible by Hong Kong standards. The Jade-Ruby routing, along with its companion course, provides year-round golf in a region where course availability is limited by geography and development pressure.
