Colombia Reef - Cozumel

Guaraguao I isn't about dizzying depths, it’s about history you can touch. At a shallow 15 metres, it’s a friendly dive, great for knocking off some rust or introducing new divers to something beyond a simple reef. This isn't a modern wreck, mind you. Here, you're exploring an artificial archaeological site, laid out with cannons, cannonballs, and old muskets salvaged from a sunken galleon. We love the way the coral has started to claim these historical artefacts, painting them in oranges and purples. You’ll spot plenty of typical Caribbean residents around the scattered pieces: yellowtail snapper drift past the cannon barrels, angelfish pick at the encrusted metal. Keep an eye out for nurse sharks tucked under ledges, and we’ve occasionally seen eagle rays glide over the sandy patches between the "debris." Our favourite part is lingering over the muskets, imagining the hands that once held them. Visibility averages 18 metres, often allowing the sunlight to dapple right down to the sand, illuminating the scene beautifully. This is a wonderfully relaxed dive, rich with a sense of the past.
