I am just about the processes of writing a short story and I am looking for a word/phrase that can properly describe a departure, without a destination(I am not going to specify anything to reflect the tone and theme of my story) that is just taken based on whim and for self discovery purposes. Is there a good way of describing something like this?

Since I don't know the context of your story... ????

You might say the character boarded a train not knowing where it was going...or started driving on a highway that was unfamiliar...or stowed away on a tramp steamer...any mode of transport that you choose, as long as the destination is unknown.
Or -- She stomped out, slamming the door, and disappeared into the darkness.

The stranger slipped into the fog and was hidden from sight.
