Box jellyfish warning in Krabi: Safety tips for tourists

Krabi's national park authorities issued an urgent warning after three tourists were stung by box jellyfish near Bamboo Island in the Phi Phi archipelago. Fortunately, all injured tourists received treatment and are now recovering.

Warning signs have been put up in Had Nopparat Thara-Mu Ko Phi Phi National Park, advising tourists and marine activity participants to be cautious. The affected areas include Bamboo Island, Ao Nang, Muang Krabi and other popular marine locations.

National park chief Yutthapong Damsrisuk stressed the highly venomous nature of box jellyfish. Their stings cause great pain and can affect the skin, nervous system and heart, potentially leading to death.

Following the incident, where tourists were immediately rushed to Phi Phi Hospital by tour operators, the Department of National Parks, Wildlife and Plant Conservation (DNP) advised on immediate action to be taken if stung by a box jellyfish. It is important to scrape off the tentacles with a hard object, avoid direct contact and apply vinegar for at least 30 seconds. Avoid using freshwater, as this can make the spread of the venom worse.

Box jellyfish are common in Thai waters, especially in Krabi, Phuket and the southern provinces. Their transparent bodies and long tentacles make them easily recognisable, but their venom is one of the most powerful in nature, causing rapid death if left untreated.

Tourists are urged to be cautious, wear protective clothing when swimming and keep vinegar readily available to minimise the risk of box jellyfish stings.
