The RSGC, located in the prime section of the Golden Triangle district of the city centre, is indeed a sanctuary beneath the vibrancy of the happening Kuala Lumpur. Against the backdrop of the city skyline, the iconic Twin Towers forms a magnificent view over the golf courses. Many international shopping havens and wold class hotels, as well as exclusive residential enclaves and embassies rows, are just a stoneβs throw away. With the convenience of a strategic location, the Club is centrally accessible from all parts of the town and outskirts through a well-connected transport infrastructure link. Heading south along the expressway, the Kuala Lumpur International Airport (KLIA) is easily within reach in about 30-minutes drive.
