Always the same cheap resentment, as if only millionaires do such things.
There are tons of regular working and middle class and even poorer people bicycling, walking, etc huge trips for months and years. Some are basking, some are working odd jobs, some save money up for half a year (and I'm talking random job money, not FAANG level salaries) and travel the rest, etc. I had a friend who spent his 20s working at supermarkets, retail, or sometimes as a waiter for half year (the hot, demand-wise season) and doing nothing the rest, leaving off the money.
If you don't have a family (or health problem) all it takes is the willingness to do it and to withstand some hardship - that is, not expect to also keep all regular luxuries). If you're worried about how it would look on your resume, or can't fathom leaving your cushy desk job, then that's on you.
Heck, in this day you can even travel, leave abroad, have fun, while keeping a regular remote job. I've done 2-3 large trips abroad while working remotely, and it was covid time too! Yes, I had to work late night shifts to sync, because I was on a totally another timezone to the expected by the customer. But I still had my 8 hours for sleep and 8 hours for play.
I can attest to this. I have met quite a few 'transient' coworkers who join the org for 6 months. They then use that money to go away to their actual pursuits for 6 months (sometimes 2 years). One of them went on a bicycle from London to Beijing. Another went on a 'back of the truck' tour of South America. They are competent enough at our job (software dev) to drop back in when they feel like, and orgs are happy to have them back, but it's not their passion, just a means of support.
I met a couple of argentinian teachers in the southern Mexico with two small kids, that lived in a hostel and drove from Argentina in a 1960s Ford. It took them 4 years. One kid was born on the road, in Costa Rica. The other was about 6. When they needed money, they would stop in a hostel for 6 months and teach.
