    El Secreto, off Costa Rica’s Caribbean coast, has a reputation for keeping you guessing. We usually find ourselves exploring a shallow reef, topping out at around 17 metres, though you’ll often find yourself shallower. Visibility averages around six metres, which isn't the best, but we've seen it push ten on a good day, so don't write it off. What makes El Secreto our favourite here isn't the expansive vistas, but the chance to really slow down and focus. This site is all about the little things. We've spent entire dives here within a small area, spotting Roughbar Frogfish tucked away or watching Antler Dragonets dart across the sand. Look closely for Yellow Snake Eels peeking out, or the striking colours of a Blackfin Soapfish. Currents can be unpredictable; sometimes you'll be zipping along, others it's a calm drift, perfect for macro photography. We'd suggest going with a guide who knows the site well – they're key to uncovering its tiny wonders. It suits divers who appreciate detailed observation over wide-angle views, and who don't mind a bit of a treasure hunt.
