Ferns and tropical plants hanging in the middle of the sky can only be reached through Wailua River in Weiluya. It used to be the imperial garden of the Hawaiian Royal family. Because we can't wear shoes when we paddle boat, we just leave them on the shore. When we get here, we find that we have to walk barefoot in the jungle. Fortunately, it's not very far. Kayak can stop at a fairly well-built pier on the other side of the bank. My paddle boat was thrown aside directly, but there was still some difficulty in getting out of the river. It was mainly because barefoot was inconvenient to pull up a very thick tree root next to it.
