Visit some of Thailand's best snorkelling reefs at Koh Racha Yai and Koh Racha Noi – two idyllic Racha islands, sometimes referred to as Raya island. Their quiet tropical beaches stretch endlessly with white powdery sand along crystal clear turquoise waters, teeming with amazing marine life. Koh Racha Yai, a 45-minute speedboat ride from Phuket, is a popular tourist attraction, but 5 Star Marine can take you a little further to its smaller twin, Koh Racha Noi, as well. It's an interesting uninhabited rocky island with plenty of fantastic snorkelling bays. You can make a stop at Mai Ton island, where dolphins frequent. This VIP private tour is completely customisable, so you get full control over planning your itinerary.
