Lanikai Pillbox Hike (Ka'iwa Ridge Trail), Oahu

The Pillbox Hike in Lanikai , also known as the Ka'iwa Ridge Trail, is a fun thing to do before or after visiting Lanikai Beach. The trailhead is easy to reach by car or if you come here with the bus (Route #70). It's a short hike to the top (about 20-30 minutes) and the views are amazing.

The trail overlooks the upscale neighborhood of Lanikai and its amazing white-sand beach, as well as Kailua and Waimanalo Beach . The two islands on the horizon are the Mokulua Islands, a popular kayaking destination.

Along the way are two military bunkers (pillboxes) that people use as lookout points. There isn't much shade on this hike and the trail can be slippery, especially if it has recently rained. It also has a few areas that are narrow (about 4 feet wide) and with a steep drop-off, so be cautious in these areas.

Frequently Asked Questions

Why is it called the Lanikai Pillbox Trail?

The nickname comes from the old concrete military observation stations on the ridge. Many hikers use the first two pillboxes as turnaround points.

What makes the view from the trail special?

The ridge faces the Mokulua Islands, Lanikai Beach and the bright water of Kailua Bay, so the view opens quickly even before the first pillbox.

Is the trail better at sunrise or later in the morning?

Sunrise brings the classic photo angle over the ocean, while later morning makes the footing easier to see. Midday can be hot because much of the ridge is exposed.

How does it compare with a beach visit in Lanikai?

The trail is a dry, exposed ridge climb, not a beach walk. Many visitors pair a short hike with time near Lanikai or Kailua Beach afterward.

What should photographers know?

The best-known photos frame the pillboxes, turquoise water and Mokulua Islands together. A wide lens helps, and early light usually gives the ridge more texture.
