I want to travel and ask my parents for money. I don’t want them to know how I can get it.

First of all, you have to ask how old you are. If you are completely able to walk alone, you can ask your parents for money. If you are afraid that they will know, it is just because you are afraid that they will not ask you to go. This is also a sign that you are worried about your concern. You can try to make it clear. There are ways to ask for money without telling you, but I can't tell you. It's better to make it clear. If it doesn't work, don't go. You can go again in the future. It's better than hiding it from you in the future or something like that. Much better.
