What is the difference between the above three words?
An "outing" has the idea of being fun, an amusement. It's the least common of the three.
A "journey" has the idea of being long. For me, and African safari would be a journey. If I were to take three weeks and explore more of my own country, that would be a journey.
A "trip" is the most versatile of the three. You can go on a trip for your vacation ("We made a trip to Disney World") or you can make a five-minute trip to the grocery store. In my experience, it's the most used of the three.
Do you want to write a couple sentences using them to see how they look?

Thank you very much. Yes, please write some examples. Thank you
Why don't YOU write the sentences in which you're not sure which word to use. My reply did have some samples.
