Lost City of Gold, Steel roller coaster at Sunway Lagoon, Malaysia

Lost City of Gold is a steel roller coaster at Sunway Lagoon featuring trains with six cars that accommodate 24 riders across two rows per car. The track winds through multiple tunnels and over hills while maintaining a traditional out-and-back layout without inversions.

The ride first opened at Bayern Express in Dolancourt, France in 1988 and operated there until 1993. It was relocated to Sunway Lagoon in Malaysia in 1994, where it has remained in operation.

The ride's name comes from its setting in Sunway Lagoon's Lost City of Gold zone, a themed area built around a fictional lost civilisation. The coaster itself is a Soquet mine train, a model type recognisable by its linked open cars and low, winding track. Visitors often mistake it for Rolling Thunder Mine Train at Genting Theme Park, another Soquet mine train in Malaysia, closed since 2011.

The ride sits in Sunway Lagoon in Subang Jaya, Selangor. Its six-car train carries 24 passengers, seated two per row across four rows per car, so groups of four can ride together in one car. The coaster is a Soquet mine-train type, the same model as Rolling Thunder Mine Train at Genting Theme Park, which closed in 2011.

The coaster was designed by manufacturer Soquet and features multiple tunnels that create moments of darkness during the ride. This design choice makes the experience less predictable as riders alternate between bright daylight and narrow dark passages.
