OK, Mar Azul is not technically a beach, but it’s a must visit! Mar Azul is an expansive area made up of volcanic rock. At low tide, a bunch of tide pools with healthy ecosystems can be found in hidden holes. The tide pool pictured is one of the largest and deepest ones. You can slide yourself in and gaze over the powerful ocean waves crashing against the rocks. Just watch out for sea urchins! #costarica #views #beach
