CAN or COULD - Please help me!

Hello everyone, I have read many articles about CAN and COULD. But I'm still confused in some situations. For example, there's a writing test with the topic: 'Describe a place you want to visit.' In the writing, I could write, for example: "I want to visit Paris because of many reasons. Firstly, I CAN see many beautiful scenes... Secondly, I CAN learn French better ... " I wonder that I should use CAN for these sentences (because they are real possibilities) or I should use COULD (because at the moment I'm not in Paris, I just know/imagine that I like to visit Paris because when I go there I could do those things)? Please pardon me if I made any mistakes - I'm not a native speaker. Could anybody help me?
