Along Kuhio Highway (Hwy 560), Haena HI 96714
About a half mile past mile marker 8 on Hwy 560, park on the side of the small dirt road. Parking is limited at Tunnels Beach. In recent years a paid parking area was created on a grassy area across from the beach, but it costs $10 to park here. Alternatively, you can also park at neighboring Ha'ena Beach Park and walk to the right along the beach to get to Tunnels Beach.
