"Aufregend" sounds fitting to me as a native German speaker. In most contexts I would translate it as "exciting". It can have some more negative connotations, in the "getting worked up" sense, but mostly when used like "sich über etwas aufregen" (so as a verb not an adjective), and when describing your feelings regarding this event it's more on the "exciting/thrilling" side.
