Goat Island, which is hundreds of meters away from the coast, is a green and quiet unmanned island. The sea is clear and suitable for diving. There is also an ornamental boat with a glass bottom, which can see fish in the sea once every 45 minutes. What's different is that there are many big reefs on the bottom of the sea, and there are very few sand. When you step on the slippery reef, you feel like you will fall down immediately. The waves are not very big and you lie in the sea. It's so pleasant to float in the water! ____________
