Another waterfall in the Wailuku River Basin along with Rainbow Falls is PeePee Falls. PeePee Falls is relatively unknown. At the bottom of a small valley, it was once open for people to go upstream and play. Nowadays, railings have been blocked by the surrounding area due to danger, but many locals will climb the railings and stand on the cliff and jump into the deep pool. I followed them to find out. PeePee Falls is the last attraction of all the itinerary in Hawaii. When I left, I bought a rainbow shaved ice with Hawaiian characteristics to finish it. Although the rainbow shaved ice is not very delicious, the gorgeous colors make people very happy to eat, just like Hawaii, like the Rainbow Continent, the moment I stepped on her, I couldn't stop the warm and unrestrained desire to embrace her with open arms.
