    The USS Cisco. Now, this is a wreck we often chat about when someone asks for something a bit different in Bohol. Forget your typical reef dives for a moment. This 1942 Balao-class submarine is a true historical relic, and it feels like diving through a time capsule. We’re talking about a significant piece of history here, not just a rusty hulk. Finding the Cisco is part of the adventure, given its depth. But once you descend, the sheer scale of the submarine reveals itself. The visibility here can vary, but even on an average day, the outline of the sub emerging from the blue is quite dramatic. We love how the wreck isn’t just a static display; it’s become a vibrant, living habitat. Look closely, and you’ll spot dashed-line blennies peeking from crevices, and we’ve even had fleeting encounters with sperm whales in the area, which is always a heart-stopper. Exploring the conning tower and imagining the crew’s final moments really makes this dive resonate. It’s a dive for those who appreciate history as much as marine life, a quiet contemplation among the metal and the soft corals. We’d suggest going early in the morning for the calmest conditions.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
