So this is what the internet says Lac Rose will look like
And this is what it actually looks like
It is still a really nice lake, it's just not always pink. My host mom explained (if I understood correctly) that the reason it's pink has to do with a certain type of algae that grows in the water. It is only pink with the right combination of sunlight and wind during the dry season, so it's kind of just luck whether it will be pink on any given day. It is also really salty, so you can float on the water like in the dead sea. I didn't know that before going so we didn't try swimming, but it is apparently also pretty common to get infections or diseases in the water so it's probably just was well. My host mom also explained that there used to be no regulations on who could go and collect salt from the lake, so over the years people took a ton of salt, and this may be part of the reason why the pinkness has faded over the years. When my host mom visited years ago though, she said it really was the color of the google photos.
