travel or trip?

"When is your next travel?" or "When is your next trip?"

I received 2 answers saying that trip is the more appropriate word to use in this sentence. Unfortunately, I didn't receive any explanations why. Could someone help me please?

When is it right to use the word travel and the word trip? And can't I use the words interchangeably?

Do not use "travel" as a singular noun like that.

Your travels may take you around the world, but you go on a trip.

Thanks Barb_D. Now that you mentioned that, may I ask if it's correct to say: "Let's talk about travel".

Absolutely. "Let's talk about travel" is a comment which frequently results in long and interesting discussions about where people have visited.

...except that phrasing it so suggests introducing the lesson plan of a primary school teacher to her class.
Most native speakers would introduce the topic with:
"Do you like to travel?"

I would say that the context of the usage has a lot to do with it. Consider people who are chatting over dinner. Having exhausted a previous subject, and sitting in silence, someone says "Let's talk about travel" as a way to get the conversation started again.

Or, in the case of two people who haven't chatted in a while, one might ask "What shall we talk about?" with the other replying "Let's talk about travel."

There is no indication that the originally posted query was intended to be a question -- such as, "Do you like to travel?"

The query asked if the phrase was correct, and acceptable. It is.
