The constant watery assault on Oahu this winter has caused the closure of one of the island's most popular hiking trails, the Manoa Falls trail. The state Department of Land and Natural Resources closed the trail, located in Manoa Valley just a few minutes from Waikiki, due to a land slide. The trail will remain closed indefinitely.
