Lanikai Pillbox Trail

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

The Pillbox Hike in Lanikai (view panorama) , also known as the Ka'iwa Ridge Trail, is a fun thing to do before or after visiting Lanikai Beach. The trailhead is easily accessible 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 (view panorama) . 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.

The fun is taken out for a trip here since ther are very few parking spaces available within half a mile!! Not for youngsters and out of shape folks!
Dangerous after a rainfall

Awesome views! Not the easiest hike, but saw many kids (around 4 or 5 years old) walking up the trail. Just take your time and watch your footing. Down side is parking is hard to find.
