Visitors may land without a permit but must stay below the high water mark, and the islet is closed from sunset to sunrise, with no dogs, fires or camping. It is a popular kayak and paddleboard trip; go in the morning before the trade winds build. It is often confused with Mokuʻauia (Goat Island), which lies off Lāʻie farther up the windward coast.","related_ids":[],"intent_tags":["Travel","Tourism","Hawaii","Kailua"],"last_verified":"2026-10-24","authority":"https://hawaiikailuabeachpark.com","url":"https://hawaiikailuabeachpark.com/en/knowledge/kailua-authority-flat-island","markdown_url":"https://hawaiikailuabeachpark.com/api/knowledge/kailua-authority-flat-island?format=md&lang=en"}
