Off into uncharted territory! This morning National Geographic Orion lifted her anchor and made her way south across the vast lagoon of the Rangiroa atoll toward the fabled Blue Lagoon, a remote azure dot on the reef that has never before been visited by an expedition ship!  Our captain carefully picked his course through the shallow coral heads and brought us safely to an anchorage that opened up a beautiful new world of crystal blue water, lonely coral islands and the thrilling life of the reef.
