The Kaiwa Ridge Trail, also known as Lanikai Pillbox Hike, is an intermediate hike that will take you to some of the most stunning views on Oahu’s windward side. Sitting above Lanikai Beach, Kaiwa Ridge Trail has a steady steep grade throughout the climb.
Access begins with the neighborhood. The new Oʻahu plan listed on HTA's destination management plan hub identifies Kaʻiwa Ridge/Lanikai Pillbox as a visitor-pressure hotspot. There is no trailhead parking lot, and daytime parking restrictions apply in the surrounding neighborhood. Managed-access and “park once” transportation ideas are being evaluated; do not assume they are operating. Check current posted signs and official transit information, never use the country club lot or block a driveway, and avoid circling residential streets in search of a space.

Before you drive to the trailhead, check the trail and weather layer.
Hawaii hikes can change quickly with closures, rain, mud, heat, and daylight.
However, if you’re up to it, you will enjoy unbeatable views of the Mokulua Islands, Kailua Beach, and Lanikai Beach when you reach the top. It takes about an hour to 90 minutes roundtrip and you can choose how far up you wish to go. In hand with the steep grade, you will also be walking a trail with a lot of slippery gravel. Some people find the grass beside the trail is safer and the trail worth the effort to reach the stunning vista.
If you aren’t up to the full trek, the first pillbox is only about 20 to 30 minutes away. You can choose to turn around here or travel another 10 minutes or so to reach the second lookout and pillbox. The scenery along the trail offers broad coastal views whether you turn around at a pillbox or continue farther along the ridge.
There is no formal trailhead parking lot. Do not park in the Mid-Pacific Country Club lot, block a driveway, or repeatedly circle residential streets. Use only parking that is legal under current posted signs, or check current TheBus and City transportation information for a park-once approach. Keep voices, doors, and music quiet while walking through the neighborhood, especially early in the day. If you cannot reach the trail without adding to the access conflict, choose another hike.
Whether you are a fitness enthusiast determined to run the trails or more of an ambler, you will find the ideal hiking trails to lead you to the unmatched views of Oahu.
