Looking for a scenic, family-friendly hike on Oʻahu’s Windward side? The Lanikai Pillbox Hike, also known as the Kaiwa Ridge Trail, is a short but rewarding trail that offers some of the best panoramic views on the island. Popular with both locals and visitors, this moderately challenging hike near Lanikai Beach takes families up to two historic military bunkers (pillboxes) with sweeping views of the ocean, the Mokulua Islands, and the Koʻolau Mountains. It’s one of the most memorable hiking trails for families visiting Oʻahu—as long as you’re prepared for the steep, unshaded terrain.
While the hike isn’t very long (just under 2 miles round trip), it does have some steep, slippery, and narrow sections—so it’s important for parents to know what to expect before setting out with kids.

What Parents Should Know Before Hiking Lanikai Pillbox with Kids
1. Trail Conditions and Safety
- The trail begins with a steep incline and loose dirt. There are no handrails or fencing in many sections.
- Some scrambling is required, especially in the first third of the hike.
- If it has rained recently, the trail can be muddy and slick. Shoes with good grip are essential.
- Portions of the trail run along cliff edges with no guardrails, so keep a close eye on young children.
- The trailhead is located just outside the gated Lanikai residential community, across from the Mid-Pacific Country Club on Kaelepulu Drive.
- There are no signs at the trailhead, but the dirt path leading upward marks the start.
- You’ll first reach the lower pillbox, then can continue another 10 minutes to the upper pillbox, which offers even better views.
- An optional final climb to the highest point on the ridge (603 ft) leads to a concrete survey marker.
How Long Does the Lanikai Pillbox Hike Take?
- To first pillbox: About 20–30 minutes
- To second pillbox: Another 10–15 minutes
- To ridge summit: Optional 10 more minutes
- Total round-trip time: ~1 to 1.5 hours depending on rest stops and pace
Many families choose to hike just to the first pillbox and back, which still offers stunning views.
