Eder´s Trident is a shallow bay formation off Mindelo built around three rock peaks and white sand, with bigger schools of fish showing up as the rocks stretch into deeper water. It suits calm-day scuba, freediving, and snorkeling more than drift-style diving, and the relaxed geometry makes it a useful local option when you want a short session without a long boat run. Plan it for calm surface water, because westerly swell can make the entry and the rocks less comfortable.
