Kaʻena Point State Park

"Kaʻena Point Ancient Hawaiians believed their souls would leap into the spirit world from this lava shoreline on the western tip of Oahu. These days, people jump off here in gliders instead, soaking up views of the Waiʻanae coast to the south, Mokuleʻia to the north—and the glorious, denim-blue Pacific stretching from here to eternity. Take a 5.4-mile round-trip hike and check out the albatross sanctuary on Kaʻena's wild coastal acreage (free to visit). Keep an eye out for monk seals, one of the world's most endangered species, found only in Hawaii. Watch for their silvery-gray sausage shapes as they lounge on the beach, but give them space. Always retreat if a seal awakes, vocalizes, shies away, or tries to shield a pup."
