It’s essential to have diving insurance and travel insurance before you come to Thailand. World Nomads is recommended by Lonely Planet as the best travel insurance – it’s reasonably priced and can be easily bought online.
Make sure you don’t forget to buy diving insurance before you go scuba diving in Thailand. The cost of medical procedures as well as getting injured divers to medical facilities from a boat to the coastline can be prohibitively expensive – diving insurance makes sure you don’t have to face those costs yourself.
