 Singapore is a major financial hub but with that comes long hours and a lot of stress. I'm finding out how people relax in this urban city starting with a guided eco tour during low tide. Dennis is an eco guide and shows me around. We just found a hermit crab, a leaf quarter crab is using a shell to hide from its predators. I didn't realize you could see so much sea life in a place like Singapore. A few of you suggested cycling and apparently that's become hugely popular here. There is more than 200 kilometers worth of cycling routes. I've cycled all the way to the Marina Barrage. It might be hard to tell from here but that is a dam that was built to keep out seawater. I actually learned that from one of your comments. And now it's become a popular recreational spot. And these super trees behind me are not just here to look pretty. They are also vertical gardens that capture rain and sunlight to use as clean energy. So despite the skyscrapers, Singapore's variety of beaches and gardens make it easy to unwind.
