In 2019, two Norwegian women dived into a Venice, Italy canal for a swim and a few hours later they ended up at the local police station. They were fined around $3,000. It is illegal to swim in canals because it is dangerous.
A few thousand miles away and at a different time, two Czech tourists were arrested in Bali, Indonesia for taking a bath at the holy fountain at the Sacred Monkey Forest Sanctuary and posting the video online.
While both these cases are extreme, the takeaway is the same – to know the basic dos and donts before travelling to another country.
