Bungalow Bay, Racha Yai: sheltered reef diving in Phuket

Bungalow Bay, often referred to as Patok Bay, is situated on the northwest side of Racha Yai island. The site is a relatively shallow reef system that benefits from its specific orientation, which provides natural protection against the prevailing winds and swells coming from the east. This makes the bay a preferred choice during the high season when conditions elsewhere in the Phuket region might be more turbulent. You will typically arrive by boat from Phuket or Chalong, making for a transit of approximately 90 to 105 minutes.

The topography of the site is divided into two distinct areas: a northern plateau and a southern section. The northern area offers a more consistent, flatter profile that is highly conducive to buoyancy practice and formation training. As you move toward the southern sector, the reef structure becomes more complex, characterized by large rock blocks and varied relief. Both sectors transition from coral-covered slopes into sandy bottoms, providing a classic reef environment that accommodates different diving styles.

The reef structure itself is dominated by hard corals, specifically staghorn and pore corals. These formations create a complex three-dimensional habitat that supports a wide variety of smaller organisms. As you descend the slopes, you will notice the terrain shifting from shallow, sunlit coral heads to deeper sections reaching approximately 25 metres. The interplay between the hard coral structures and the sandy patches allows for a diverse range of micro-habitats within a relatively small area.

For those interested in macro photography or close-up observation, the site offers significant rewards. The sandy floor and the crevices within the coral and rock formations are home to several cryptic species. You can find various types of ghost pipefish, including the ornate ghost pipefish and the seagrass ghost pipefish, often camouflaged against their surroundings. The presence of frogfish and stonefish in the rocky and coral areas requires a slow, observant approach to spotting them.

The benthic environment is also a productive zone for larger invertebrates and mobile species. It is common to encounter octopus and cuttlefish navigating the reef, as well as moray eels tucked into the crevices of the southern rock blocks. If you keep a close eye on the sandy stretches, you might spot flounder or various nudibranchs. The presence of Kuhl's stingray is another highlight for divers looking to observe bottom-dwelling species in a calm setting.

While the site is known for its stability, the marine life remains active across the different depth zones. You may see barracuda cruising in the mid-water columns or turtles moving along the reef edges. The visibility at Bungalow Bay is generally good, ranging from 10 to 25 metres, which allows for clear sightlines when observing the transition from the reef to the sandy patches. This clarity is a key factor in making the site a successful location for both novice and experienced divers.

The southern sector, in particular, offers a more rugged experience due to the presence of large rock formations. These blocks provide essential shelter for species like the stonefish and offer more interesting topography for navigating. While the northern part remains the go-to for those needing a controlled environment, the southern side provides the visual interest that experienced divers look for when exploring the Racha Yai area. Both zones remain well within the reachable depth limits of most recreational divers.
