Known as the "Garden Island," Kauai is the oldest of the Hawaiian islands. Abundant rain makes it rich with greenery and tropical plants. Most effected by erosion of the Hawaiian islands, Kauai island has popular natural marvels like the NaPali Coast and Waimea Canyon. Because it is the oldest island, Kauai has more sandy beaches than any other Hawaiian island.
Nawiliwili Harbor has a tropical climate, although the island has many different microclimates. Temperatures range from about 30°C (mid-80s) in the summer to the low 20s ( C or 80s F) in the winter. Even in the heat of summer, trade winds cool Nawiliwili Harbor.
Nawiliwili Harbor boasts two parks that residents and visitors enjoy. Nawiliwili Beach Park and Niumalu Beach Park are both on the shores of Nawiliwili Bay. Niumalu Beach Park is a popular location for launching kayaks, and campers need a county permit.
Located about three kilometers (less than two miles) west-southwest of Nawiliwili Harbor is the Huleia National Wildlife Refuge. The Refuge was established in 1973 to protect the natural wetlands and habitat supporting several endangered species of Hawaiian waterbirds. It is adjacent to the Menehune Fish Pond, a thousand year old man-made National Historic Landmark used by natives to raise fish. Neither the Refuge nor the Fish Pond are open to the public; however, the public can get to the nearby shoreline at the Niumalu Beach Park.
