Route: Kaiwa Ridge Trail climbs up the ridge behind Lanikai on the windward side of Oahu. It traverses through native and introduced coastal vegetation and ends at the first WWII bunker. Kaiwa Ridge Trail is currently an undeveloped trail and receives minimal maintenance from the State of Hawaii. Hikers are advised to watch their step and not to climb the bunkers. Trail offers 360 degree views of Kailua, the Mokaluas and the Ko`olau Mountains.

Directions: From Kalanianaole Highway, turn right on Kailua Road into Kailua. Continue through Kailua town (road turns into Ku`ulei) until you reach a T-intersection at a traffic light. Turn right on Kalaheo Road, continuing past Kailua Beach Park, where the road` turns into Kawailoa. Heading into Lanikai, follow the right fork onto Aalapapa Dr., and take a right onto Kaelepulu Drive. When you reach Mid Pacific Country Club (on the right), park in the turnout on the right side of the road, taking note of the No Parking areas. Across the street you will see a dirt trail running along a fence. This is Ka`iwa Trailhead. The first part of the trail is very steep, slippery, and confusing. Remember! This trail is undeveloped. WATCH YOUR STEP!.
