Welcome to the Ka‘iwa Ridge (Lanikai Pillbox) Trail User Survey

The Ka‘iwa Ridge Trail, also known as the Lanikai Pillbox Trail, is an approximately 1.25 mile hiking path to two historical coast artillery observation stations (pillboxes) used during World War II. The pillboxes sit on parcel Tax Map Key 142002017 which is owned and managed by the Department of Land and Natural Resources. Situated in the ahupua‘a of Kailua, Ko‘olaupoko District, O‘ahu, Ka‘iwa Ridge is the rugged hillside that forms the backdrop of the Lanikai neighborhood. It is the summit of the crescent shaped Ka‘ohao watershed which includes the hillside, single-family homes, an ephemeral stream, Lanikai beach and A‘alapapa reef. 

This survey, conducted on behalf of the State of Hawai‘i Department of Land and Natural Resources, Division of Forestry and Wildlife, has been developed to solicit your feedback regarding your experience(s) with the Ka‘iwa Ridge (Lanikai Pillbox) Trial.
