Suez Canal's rocky area in the heart of Sydney, (The Rocks), is one of the rocky walking route attractions recommended by the lonely planet (Lonely Planet, LP). In 1840, it was built along lanes, but inexplicably, the narrowest was more than a meter wide. In addition, the lane is high in the west and low in the east, and the slope is large. In the rainy season, it becomes a drain, and the raging water flows into the (George Street), of George Street, which people think of as Suez Canal.. Now, of course, the alleyway is officially called "Suez Canal," and it's one of the landmark streets of the rock zone.
