Re trip vs. journey, see some good answers here: https://www.italki.com/question/499292. Re shore vs. beach: Not every shore has a beach. There might just be cliffs falling straight into the water. Beach is a flat area — often but not always sandy. Also, “shore” is a broader term that can include a beach area but also other areas close to the water. Example: Along the shore there was a sandy beach about 100 feet wide, some grassland behind that, then some cliffs.”

A trip is short time and a journey is like a map of where you will be going or a specific place you will be traveling past and time it will take. Shore is on the beach its where shells lie or fish, treasure and beach is where people come to bathe and spend time with one another.

"Trip" usually implies a destination (e.g., I'm going on a trip to Italy). "Journey", on the other hand, usually focuses on actually being on the road or in the midst of travel (e.g., his journey to Italy was long and difficult). You can also use journey for any kind of change in state or being (e.g., my inner journey to enlightenment). You would never say "my inner trip to enlightenment" -- "journey" is about the process of getting somewhere. Shore and beach are very similar. In some cases, the shore means the actual place where the water and sand meet, whereas the beach means the entire place (sand, water, etc.). But they both can be used interchangeably -- when people talk about the Jersey Shore, they mean the beaches in New Jersey, so same thing.
