Titan is the largest moon of Saturn and the second-largest in the solar system. It is also the only moon in the solar system to have a substantial atmosphere. It is covered with a thick smog of nitrogen and sulphur compounds, preventing astronomers from directly viewing its surface. However, planetary scientists who have studied Titan’s chemistry and temperature believe that there may be lakes or even oceans of liquid ethane on the moon’s surface. The Hubble Space Telescope, observing in the infrared range of the spectrum, was able to make out some surface features, including an elevated region that is about the size of Australia. If Titan has ethane seas, then this region may be a continent.
Titan’s atmosphere is 60 per cent more dense than Earth’s and is mostly made of nitrogen (94 per cent), with the balance made up of argon, methane, ethane, hydrogen cyanide, carbon dioxide, and other chemicals. Scientists theorize that Titan has two cloud layers: an upper layer made up of many of the same chemicals as smog on Earth and a lower layer of ethane clouds. Ethane might rain on the surface and flow in rivers to the sea, then evaporate to form new clouds in a cyclical process, in much the same way that water does on Earth.

You can look here

It says that lakes of Methane were found on it. Also it says that there is methane rain.
