To Travel
To Take A Trip
する verb
You've hopefully seen 旅行 by this point. This is the verb version of that. Instead of "trip" it's to travel or to take a trip. These are fun to do. You should do them!
The reading is the same as 旅行, but it also happens to use the reading you learned with the kanji anyways, so you should be able to read it.
いつ旅行する予定なんですか？
When are you planning to travel?
あー、旅行したいな。
Ah, I want to travel.
