Key Dive Site Facts
Dive Site Overview
This site stands out as a distinctive granite pinnacle dive off Koh Nang Yuan, characterized by its dramatic rock formations and a notable swim-through cave. Divers often embark on a controlled descent, exploring depths ranging from 2 m / 7 ft to 22 m / 72 ft, with the most engaging exploration typically occurring around 12 meters.
The main attraction here involves navigating the lengthy, scenic swim-through, formed by several large, fallen boulders; this passage artfully leads toward the adjacent coastal reef. It's a structure-rich environment, where vibrant whip corals and expansive table corals thrive, creating intricate layered habitats for diverse marine life. Many dives here transition into a gentle drift, allowing groups to safely converge for their safety stops in the shallower, adjacent Japanese Gardens.
This approach offers a seamless and engaging experience, blending an adventurous swim-through with relaxed reef exploration. It's suitable for Open Water divers, yet also offers enough complexity and visual interest for more experienced enthusiasts.
The site often features good visibility, generally over 10 meters, and consistently warm water temperatures between 27-30°C / 81-86°F.
Best Time to Dive
Planning your dive at Red Rock during the optimal season significantly enhances the experience, delivering the calmest waters and clearest visibility. The period from January to May generally offers the best conditions. During these months, average air temperatures comfortably sit between 27.2°C and 29.5°C, ensuring pleasant surface intervals. Rain is minimal, with monthly averages often below 2 mm in the peak season, which contributes to more predictable underwater clarity. March and April frequently register "Excellent" dive scores, indicating ideal conditions for exploring the pinnacle and its swim-through. While diving is possible year-round, these peak months minimize potential challenges from stronger currents or reduced visibility that can occur during other periods, particularly when seasonal weather patterns bring increased wave activity or rainfall. Expect consistently warm water temperatures, typically hovering around 28°C, regardless of the month, but calmer surface conditions are key for enjoyable access.

Dive Difficulty & Safety Guidelines
Navigating Red Rock's unique structure requires particular attention to safety protocols. When entering the prominent swim-through, maintain precise buoyancy and avoid pushing the route if visibility is compromised or currents are unexpectedly strong. This overhead environment demands competence and adherence to your guide's instructions. A local guide is often essential for managing the swim-through profile and the overall route, particularly if the site is busy. Never attempt cave penetration beyond the designated swim-through. Surface conditions can vary, with typical wave heights generally below 1 meter, but checking daily forecasts is always prudent.
