Lanikai Pillbox Hike
The Lanikai Pillboxes hike (a.k.a. Ka’iwa Ridge Trail) is a popular, relatively easy and one of the most scenic. You can complete the intermediate hike in about an hour if you wanted to. But once you see the sweeping views of Kailua and Lanikai from the ridge, you may want to spend more time on the trail. The 1.6 mile round-trip hike gains 600ft so it is steep in places with great views along the way.
