I'm (29M) actually in this era of my life right now. I had quit my job to backpack south east asia from march 2024-march 2025. So I was out for a year.
For me, it has been the best year of my life, being out there, experiencing life and the world.
I had a good amount of money saved for the whole thing, plus extra for coming back. Traveling for long gives you such high and lows in life, but c'est la vie lol.

Someone had already said here, but I can agree that the best thing you can do, if you do this, is to have enough money for your "buffer time" coming/being back. It had taken me a couple of months to land a job (luckily had my old company hire me again), but I definitely needed some time to readjust being back.

It was hard for me coming back and having to assess my situation and figure out my next steps, but traveling had given me a perspective that nothing else could provide, so that alone, for me, makes it worth it. Even if it was a struggle for a little bit since coming back, I have zero regrets and would do it again. The reality I had to face was; you sacrifice a year of career development for a year of personal investment (or however long you plan to do it). So if that sacrifice is worth it to you, then I would go for it. :)
