Best for technical divers, 6-100m, shore entry, mild current.
Song Hong is a technical cave system in Phi Phi Leh, Thailand, offering a challenging overhead environment for experienced divers. The site features a depth range of 6 to 60 metres, with an average depth of 50 metres. Divers must navigate a hydrogen sulphide layer located below 25 metres and manage significant thermoclines. Visibility is highly variable, ranging from 5 to 80 metres, and can collapse rapidly inside the cave. Due to the deep, overhead nature of the site, divers must maintain a continuous guideline to the exit, carry three independent light sources, and plan gas usage on a rule of thirds. The site is accessed from the shore.
