Perched 600 feet above the turquoise waters of Lanikai Beach, two weathered concrete structures stand as silent witnesses to World War II history. These observation posts, built in 1943 to watch for incoming enemy ships, now serve as Instagram-worthy viewpoints for thousands of hikers each year. Here’s a comprehensive guide to conquering one of Oahu’s most beloved hiking trails, from parking nightmares to sunrise magic.
Understanding the trail basics
The Lanikai Pillbox trail, officially known as the Kaiwa Ridge Trail, spans just 0.8 miles each way, with an elevation gain of 636 feet. Most hikers complete the round trip in 60–90 minutes, reaching the first pillbox in about 20–30 minutes.
Don’t let the short distance fool you—some sections are steep and can become quite slippery following heavy rainfall. The trail earns its intermediate rating from the sustained steep grade right from the trailhead.
Solving the parking puzzle
The Lanikai Pillbox Trail is the single most difficult hike to find parking for on Oahu. Residential streets have increasingly restricted visitor parking, creating a major headache for hikers. There’s unfortunately no parking near the trailhead, and parking along private residential streets is frowned upon.
Your best bet? Park at the free Kailua Beach parking area and walk about 15–20 minutes to the trailhead. Alternative spots include the seven parking spaces near the Mid-Pacific Country Club entrance gate.
Timing your adventure
Sunrise hiking offers the perfect combination of cooler temperatures, fewer crowds, and stunning views as the sun creeps over the horizon. To catch the sunrise from start to finish, begin hiking at least 30–40 minutes before it emerges. The morning light hitting the Mokulua Islands creates an almost otherworldly glow…
