We used Samara Info Center to book to turtle tour to Playa Camcaronal where we witnessed the miracle of 100,000 years of evolution. An Olive Ridley turtle mother shuffling up the same beach she was hatched on 45 years ago and laying her eggs. She got to the perfect spot for her above the high tide line amongst the driftwood, snuffled around and started digging her nest with her amazingly prehensile rear flippers. Reaching down as far as flippers would go, removing the last 1/4 cup of sand until every thing was just so, and depositing her 100 or so eggs in a zen like trance. She then buried the little ping pong sized bundles of joy and packed it all down with her hundred pound body, thumping up and down and sounding for all the world like a big bass drum in a Sousa band. A quick turn around scattering debris, camouflaging the nest's presence and she was off back to the sea, pausing often to get her bearings and rest from her exertions. Pura Vida! Our guide was Renaldo, a native of Samara and very knowledgeable about the local sea turtles and our driver took care and caution navigating along the treacherous roads at night.
