Over the years, the practice has changed. Back in the mid 90's when I was a lot younger, we started hiking at 8 am and stopped for a short lunch at noon then 4-5 more hours of hiking followed by a bowl of beef noodle soup and a couple of beers on the way home where we just collapsed.

Maybe 10 years ago, the hiking started a bit later like 9 am for several hours with a small lunch then off to a nearby hot springs (and showers and soaks) for several hours followed by a very nice dinner.

But yes, I always bring a change of clothes. We find showers at hot springs and local high schools or a pretty good wash up and change of clothes in the restaurant lav works.

But everyone in Taiwan sweats. If a group of us hike, we are all in similar conditions and everyone cools/dries off in AC. And we are going to restaurants like https://www.tripadvisor.com/Restaura...t-Keelung.html not places that have a dress code.
