The 5 Most Popular Pillbox Hikes on Oahu

Hiking is one of the most popular activities on O'ahu and with good reason. The island is home to some of the most beautiful and challenging hikes in the world, and few hikes are as popular as those that lead to World War II "pillboxes".

Pillboxes (bunkers) were built on the island during World War II to serve as lookout points and defensive positions against potential enemy attacks. Today, many of these structures still exist and have become popular hiking destinations. Here are some of the most popular pillbox hikes on Oahu:

1. Lanikai Pillbox Hike

Located on the east side of the island, this trail takes you through a residential neighborhood and up to the top of a ridge overlooking the beautiful Lanikai Beach. Along the way, you'll encounter two pillboxes, both of which offer incredible views of the turquoise waters below. This hike is a very popular sunrise spot, for good reasons. To make this hike into a loop, from the 2nd bunker you continue the trail all the way around in a U shape and descend at the end, steeply into the neighborhood. For a less crowded experience visit for sunset. You will not have the sun rising from the ocean but you will have the sun setting behind the Ko'olau Mountains makes the golden hour light very precious.
