    StandoutExceptional marine biodiversity

    Meros, over on Costa Rica’s Caribbean side, is one of those places we genuinely adore for a chilled-out afternoon dive. Maximum depth is only 12 meters, so it’s perfect for long bottom times and really allows you to slow down. Our favorite thing here is just how much tiny, interesting life you can spot. We’re talking nudibranchs in every color imaginable, little blennies peeking out of holes, and the occasional frogfish if you’re patient enough to really scour the sponges. Visibility hovers around 9 meters, which isn't 'gin-clear' by any stretch, but it's more than enough for macro work. We've often found ourselves eye-to-eye with a Giant Sand Stargazer, buried in the sand with just its alien-like eyes poking out, or watching a Trumpet fish slowly stalk its prey. Look out for Haller's round rays gliding over the sandy patches and the vibrant flashes of scissortail chromis darting through the water. It’s a photographer’s dream if you’re into the small stuff, and frankly, a wonderful spot for anyone who just wants to drift and observe without the pressure of depth or strong currents.
