On 2 July 2018, the cave was brought to international prominence when twelve members of a junior association football team and their assistant coach were found deep inside the cave. They had become trapped due to monsoonal flooding on 23 June. A rescue effort succeeded in bringing them out safely by 10 July. Two Thai rescue divers died as a result of the rescue.
The cave is also known as Tham Luang (Thai: ถ้ำหลวง, lit. 'great cave'), Tham Nam Cham (Thai: ถ้ำน้ำจำ, lit. 'Nam Cham cave'), and Tham Yai (Thai: ถ้ำใหญ่, lit. 'big cave').[2] Since tham means 'cave', the commonly used phrase Tham Luang cave is a tautology.

The cave's main entrance chamber is 80 metres (260 ft) long and the complex winds through 10.3 kilometres (6.4 mi) of limestone strata. It has many deep recesses, narrow tunnels, boulder chokes, collapses, and sumps. Stalactites and stalagmites are found throughout the cave.[1] There is a permanent stream inside the cave, which enters from the west, flows with the passage for several metres, and exits via the eastern wall.[2] A team of French cavers made the first survey of Tham Luang's main cave in 1986 and 1987. Further surveys were done in 2014 and 2015 by the British cavers Vern Unsworth, Martin Ellis, Phil Collett, and Rob Harper.[3][4][5]
A visitor centre outside the main entrance has a detailed map of the cave.[2] There is a car park nearby. The first 1 kilometre (0.6 mi) of the cave is open to the public for guided tours between November and April.[1] The cave floods during the rainy season and is closed to visitors.[1]
In 2018, twelve boys aged 11 to 16, all members of a junior association football team, and their 25-year-old male assistant coach were stranded in the cave for 18 days by a flood.[6][7] They were rescued in a massive joint operation between the Thai government, the Thai military, and a group of international expert cave divers.[8] British divers found them on a muddy ledge in darkness more than 4 kilometres (2.5 mi) from the entrance nine days into their ordeal. The effort to save their lives was a global operation watched around the world.[9] In all, 90 divers – 50 of whom were foreigners – helped to extract the group.[10][11] An ex-navy diver, Saman Kunan,[12] died during the mission[13] because he ran out of air, having placed air tanks along the route for the boys.[14] Another diver and ex-Navy Seal, Beirut Pakbara, died the next year from a septic shock from an unspecified blood infection he contracted during the cave rescue.
