About this site
Tagachang lies along the eastern shore of Guam in the Mariana Archipelago, facing the open Pacific rather than the more sheltered western coast. Sites along this stretch of coastline are typically reached by a short drive from the island's main population centers, with entry over the fringing reef into deeper Pacific water.
