Petchbury Bremen wreck - Koh Tao

The Petchbury Bremen wreck always makes for an interesting dive on Koh Tao, especially if you’ve spent a few days on the usual reef sites. This isn't a deep dive, probably topping out around 22 metres, making it accessible for Advanced Open Water divers looking for a bit more structure than the HTMS Sattakut. What we love about the Bremen is its character – she’s a former cargo ship, so the holds are big and open, inviting exploration without feeling too enclosed. Swim through the main cargo holds and you’ll often find schools of fusiliers swirling inside, using the structure for shelter. Look closely at the superstructure and you might spot a stonefish blending into the growth, or a scorpionfish perched on a rail. Our favourite spot is the stern, where the prop shaft leads down to the rudder – it’s a great place to find schooling yellowtail barracuda hanging in the mild current. We’d suggest hitting it early in the morning before the dive school boats descend; it’s a much more peaceful experience. It's not a massive wreck, but it's got enough nooks and crannies to keep you engaged for a full bottom time.
