Located in the scenic town of Tobermonry, the island is named for two large vase-shaped limestone boulders. It takes four hours by bus and more than half an hour by double-decked glass boat. Personally, I think there are a lot of similar strange stones in our country, but what impressed me is the clear lake water and the ubiquitous environmental protection concept on the island - "over 200 hectares of islands are not over-exploited but underdeveloped; the island is not allowed to leave any garbage on the island, but each person sends a garbage bag after going to the island; even the toilet facilities are very special, not flushing with water, but using sawdust.
