    Pak One is one of our absolute favourite deep dives on Koh Tao. It’s a proper wreck, a tanker that the Thai Navy finally scuttled back in 2002 after it caused a bit of a navigational hazard for weeks, just floating around. Now it sits upright on a sandy bottom at 36 metres, and the visibility here can be surprisingly good, often 20 metres or more. We love dropping down and seeing the huge, dark silhouette slowly resolve into a recognisable ship. The wreck itself is intact, a hulking metal structure. We usually start our dive around the bridge, which offers some cool penetration opportunities if you’re comfortable and have the right training. Schools of yellowtail barracuda hang off the bow, their silver bodies flashing in the ambient light. Down in the holds, you'll find giant groupers lurking in the shadows, and we’ve spotted marbled stingrays gliding gracefully off the deck more than once. The sheer size of Pak One and the depth make it feel like a real expedition. It’s a dive for advanced divers comfortable with depth and perhaps looking to expand their wreck diving experience. Come for the history, stay for the spooky, deep-sea vibe and the big fish.
