Na appears to be the largest island in Madolenihmw after Temwen, although it mostly consists of mangrove forests. In the mid-1830s, Na was home to a renegade Pohnpeian chief — the Wasai — who joined a group of foreign whalers in a fight against the Nahnmwarki of Madolenihmw and his brother, Nahnawa. The violent conflict ended with the murders of the Nahnmwarki and Nahnawa at the hands of the whalers, and the Wasai became the new Nahnmwarki (beginning a long cycle of violent power struggles in the district).
Currently Na is uninhabited. Though seagrass beds characterize the areas further out, there’s a beautiful swath of shallow, crystal clear water between them and the northern coastline. The bottom is sandy and a fantastic place to observe resident stingrays. The island itself is little more than a long, curving sandbar that has collected trees over its lifetime — mostly coconut palms. All the potential camp sites are on the northern coast as well as the beaches and best swimming. Snorkeling spots include Namwen Na Stingray Sanctuary to the north and the reef walls at the eastern edge of Pahn Nahkapw south of the island. The closest SCUBA diving is located on the reef wall around the eastern end of the island (boat access from outside the reef only). Divers usually begin there and drift on an in-coming tide along the wall as it curves west. Due to exposure to the prevailing winds, which cause heavy seas, the site is only an option during the middle of summer.
