Also in Kailua, is the Kawainui Marsh Trail. This trail travels through Kawainui Marsh, which encompasses over 800 acres of beautiful wetlands. Along your run, you will get incredible views of the majestic Ko’olau Mountains, as well as spot some endangered birds and wildlife. The 1.3 mile (one-way) half-paved/half-gravel path is quite popular among the locals and seemingly the preferred running, walking and biking route in the area. You may just want to run out and back on this trail or incorporate it into the loop mapped above.
To run the loop, take a right onto Kailua Rd. at the end of the path. Follow this road until you reach N Kainalu Dr, where you should turn left. Run along through residential neighborhoods until you reach Kaha St. Turn left and complete the loop. Parking is available at the end of Kaha St. To get to this route by bus take Route 56 — Kailua-Kaneohe from Ala Moana Center, until the intersection of Oneawa and Kaha Street. Walk less than half a mile to the end of Kaha, the trail is on the right.
