During summer vacation, my family and I went to Green Island which is just about 130 kilometers away from Taiwan. It turned out to be very hot there despite being surrounded by the Pacific Ocean, hence its nickname "Fire Island". The island wasn't very large as it was originally a place for prisoners, and only had a road that circled around it. As our tour guide drove us along the winding path, he explained that water activities are usually on the west side of the island because the ocean floor has a gradual slope upwards to the shore on the west unlike the steep slope on the other side of the island, thus the ocean waves are calmer on the west than east. Indeed, when our tour guide drove further towards the east side of the island, the light-colored, gentle, lapping ocean waves shifted to a deep shade of blue, rolling fiercely. Fascinated by the dramatic change of scene, I immediately told him to stop by the side of the road and whipped out my camera. Unlike the usual beach waves that I've often experienced, the wild waves crashed powerfully against the giant rocks as the sea breeze blew, spraying misty seawater everywhere. I stood in that spot for a long time, sweating under the hot sun, trying to take a good shot. Never have I seen such a stunning sight: the dark ocean water churning restlessly, along with the vivid green mountains and the clear blue sky, and you could even see other lands in the distance.
