Volcanic rocks cooled from lava explosions compose the structure of the 180 kilometer coastline, twisting in weird formations along the highway. Cliffs and unpredictable sands are everywhere. This stretch of road is highly favored by the more fanatical hikers and bicyclists.
例如以集塊岩為主要結構的東海岸長約一百八十公里，沿著公路，奇岩、險灘、斷崖處處，是熱愛健行或自行車旅行者的最佳路線。
