There are many tour operators that offer snorkelling tours to these islands, and the tours typically include round-trip transportation from your hotel, snorkelling gear, and a guided tour of the best snorkelling spots. Some tours may also include lunch or other amenities.
When snorkelling in Koh Tao and Koh Nang Yuan, you can expect to see a variety of marine life such as colourful fish, coral reefs, and possibly even sea turtles. It’s important to follow proper snorkelling etiquette and guidelines to protect the delicate marine ecosystem and ensure the safety of yourself and the animals.
It’s a good idea to book your tour in advance, especially during peak tourist season, to ensure availability. It’s also a good idea to bring sunscreen, a hat, and a towel, and to wear a rash guard or other protective clothing to protect your skin from the sun and any potential irritants in the water.
