Red Rock Pinnacle is a grand granite formation that reaches almost two meters beneath the sea, at depths of 60 to 66 feet (18 to 20 meters). It’s perfect for divers of all levels and experiences – often used as an amazing drop-off spot. Planned as a drift dive, you can explore Red Rock and then swim with the current along the shore to Japanese Gardens. That way, you get two Koh Tao dive sites with one tank. However, don’t miss out on exploring the Nang Yuan cave.

About Red Rock/Nang Yuan Pinnacle dive site
The Red Rock dive site is also often referred to as ‘Nang Yuan Pinnacle’. Located off Koh Nang Yuan’s east coast, the Red Rock Pinnacle dive site on Koh Tao offers a journey through the eastern waters and finishes in Japanese gardens for an extended underwater experience.
Fun fact: most pictures you see of Koh Tao are actually photos of Koh Nang Yuan.
Red Rock itself is a small pinnacle with a maximum depth of 66 feet (20 meters), reaching just shy beneath the surface. On the Eastern and northern sides of the Pinnacle lies a large crack that provides a haven for captivating aquatic creatures.
When diving Red Rock Pinnacle, you have two options: Continue straight to Japanese Gardens or stop at the Nang Yuan Cave.
The dive plan for Red Rock/Nang Yuan Pinnacle in Koh Tao
Your dive journey begins by descending along Red Rock to depths of 60 to 66 feet (18 to 20 meters). The maximum depth of the dive site is 72 feet (22 meters) with an average of 33 ft/10 m. The pinnacle itself as a dive site is quite small in size, so you’ll have plenty of opportunities to explore its ridges and crevices at a leisurely pace. Don’t forget your flashlight – who knows what you might find.
After you complete a loop around Red Rock, set your compass westward and journey to the shore. There, tucked away among coral walls, lies the entrance of Nang Yuan cave.
The entrance to the cave begins at approximately 36 – 39 feet (11–12 meters). Visiting Nang Yuan cave is a mesmerizing experience, as its long hallway provides perfect backdrops for serene swim-throughs. As you pass through the massive boulders that form an underwater chamber, beams of light penetrate from above and illuminate your path. Looking up reveals the various silhouettes of small fish inhabiting this cavernous wonderland.
Keep your eyes peeled for Blue Spotted Ribbon Tail stingrays and the Jenkins Whipray, who often inhabit the depths of this cave.
From here, you have two options, swimming back to Red Rock or continuing to Japanese Gardens.
As you scuba dive along the eastern Nang Yuan shoreline, your eyes will be treated to a tremendous spectrum of color and various landforms featuring gigantic boulders bedecked with both hard & soft corals. You’re likely to spot plenteous marine life including Bannerfish, Angelfish, Beaked Coral fish, Red Breasted Wrasse, and Parrot fish among many other species.
Reaching a drop-off, you will enter the Japanese Gardens dive site.
In order to make it to all three sights, it will require good air consumption.
Alternatively, you can also make your way to Japanese Gardens and skip the swim-through at Nang Yuan Cave. In that case, it’s a drift dive and the diving boat will pick you up at Japanese Gardens. For safety reasons, make sure to bring your inflatable dive marker.
