U.S. Naval Radio Station Haiku

U.S. Naval Radio Station Haiku is a former military communications site in the hills above Kāneʻohe on O‘ahu’s windward side, known today more for its historical significance and secluded setting than for public visitor facilities. It sits in a lush, quiet part of the island where the landscape itself helps explain why radio and communications infrastructure once mattered here. For travelers interested in military history, Cold War-era infrastructure, or lesser-known O‘ahu sites, it offers a sense of place that is very different from the island’s beaches and resort areas.

History

U.S. Naval Radio Station Haiku was part of the U.S. Navy’s communications network in Hawai‘i, taking advantage of O‘ahu’s strategic location in the Pacific. Like many military radio facilities of its era, it supported naval communications rather than serving as a public attraction, and its remaining structures are associated with the broader history of U.S. defense operations in Hawai‘i. Today it is generally recognized as a historic military site rather than an active station.

Expert notes

• Do not assume public access; verify whether the site is viewable from outside only.
• Wear sturdy shoes if approaching nearby trails or uneven terrain.
• Treat any remaining structures as historic resources and avoid entering fenced or posted areas.
