3. Riff is a Boca Chica reef built like an underwater mountain, with steeper faces that make it a clear fit for advanced divers. The site rewards a slow, deliberate route across the structure, where you can work the ledges, stay organized on depth, and watch for larger life moving along the reef. Plan it as a guided boat dive from Boca Chica and treat it like a serious reef day rather than a relaxed lagoon stop.
