How do you decide if it's le or la?

Think about a vacation you want to take in the future. how will you get there? write five sentences saying where you want to go and how you will travel. each sentence should include a method of transportation according to the rules you learned this week. do not copy directly from the example below or from any other source. (so i assume it needs to be in french) example: je vais voyager à paris en avion.
