Pulau Ubin is an islet just off the coast of Singapore. It only takes 10 minutes to get there, but it's a world apart from the city. Few vehicles are permitted on the island, most roads are unpaved, and but for day trippers it's now mostly uninhabited. It's so quiet you might imagine that not much has changed on the island since the late 1880's when it was first settled, but that's not exactly true.
What is true is that the trees planted by those early settlers are now huge, and their durians are both awesome and free, if you can find them.
