Nearly everyone who starts a travel channel comes home from the first trip with four hours of footage and no idea what to do with it. The filming was never the hard part. Cutting that four hours into six watchable minutes is, and it is the stage almost nobody prepares for, which is why a travel vlogging course earns its place before the next trip rather than after it.
The useful ones are honest about covering three separate jobs.
Shooting comes first, and travel makes it harder than studio work - you get one pass at a location, usually in bad light, often with a stranger waiting for you to move. Courses that teach coverage and sequences rather than single beautiful shots are the ones that save you in the edit.
Editing is second and it is where most channels quietly die. Pacing, sound and knowing what to cut are learnable skills with rules, not taste you either have or lack. Then third comes the audience side - titles, thumbnails, structure, the reason someone clicks a video about a place they have never heard of. A course that covers only one of the three will leave a visible gap.

Six that between them cover all three stages, listed in the video course catalogue.
The most directly on-topic of the set, built around travel vlogs specifically rather than video in general. It deals with the awkward parts nobody warns you about - talking to a camera in public, and finding a narrative in a day that did not have one.
Broader and more craft-focused, covering camera work and sound as a whole discipline. A good foundation if your footage looks amateurish and you cannot pin down why.
End to end, from filming through to publishing. The publishing half is the part most creators improvise badly, so a course that treats it as a step rather than an afterthought is worth having.
Audience-side rather than craft-side. It covers what makes a video get found and clicked, which is the difference between a channel with an archive and a channel with viewers.
Pairs the writing with the filming, which matters more than it sounds - the script, or at least the structure, is what stops a vlog turning into a walking tour with commentary.
A current, beginner-level run through the whole process. Sensible as a first purchase if you want one course rather than three and are willing to go deeper later.
Edit something small before the next trip. Applying a module to a two-minute cut of footage you already have is where the lessons land, and it exposes the gaps in your shooting while there is still time to fix them. Most video editing courses set an exercise like this early for exactly that reason.
Publish the first few even if they are rough. A channel with six imperfect videos improves faster than one with a single perfect video, because the feedback loop only starts once something is out.
Take the stage you are actually stuck on. If the footage is fine and the videos are dull, that is an editing and structure problem and no amount of new gear will touch it. If nothing gets watched, the craft is not the issue and the audience-side course is the better spend.
The whole set is on Udemy, so you can enrol in the vlogging course covering the stage you are stuck on and work through it before the next trip.
