Porto Mari - Curaçao Southeast
Sidem has always been a reliable pick for us when we’re in the mood to go small. While some sites get all the glory for big pelagics, Sidem delivers on the tiny, the camouflaged, and the downright weird. We love drifting over the sandy patches, eyes peeled for frogfish – the freckled anglerfish here are particularly good at blending in, so you need to look carefully, maybe even twice. The staghorn coral patches act like little cities, full of palebarred reefgobies flitting in and out, and if you’re patient, you might spot a seahorse clinging on. It’s a site for the slow explorers, the ones who get a thrill from finding a Sargassum nudibranch the size of a fingernail, or an elegant sandburrower disappearing into the substrate. Maxing out at 21 meters, it’s a calm, shallow dive, perfect for photographers or anyone wanting to spend an hour just observing the smaller residents of the reef.
