*** Spoiler - click to reveal ***After crossing the bridge and taking a nap, you'll come across two paths. You'll want to go left, and then continue down the path. There will be a well that you can inspect. Your character will see a coin, and you'll need to choose to grab it. Your character will attempt to climb down, but ultimately fall into it and drown. Don't worry though, the splash you make from falling in from such a height causes an achievement to launch out of the well.
