The light from the entrance thins as you step into Sarudado; the limestone walls cool the air and the soft scrape of rubber boots answers the cave’s hush. You don a black costume, swap stories with your instructor, then move deeper where low tunnels and tight turns test balance and quiet focus — the environment is part obstacle course, part lesson in restraint.
