Who discover river Niger and what year was it discovered?

It is often said that it was MUNGO PARK who discovered river Niger; however we all know that is as true as saying Spiderman invented trafic lights.

Who was the first European to discover river Niger? Mungo Park.

Who discovered river Niger? I dont know but i think my bet would be that it was a member of the community that lived in the region of the river Niger. I mean there were communities that fished in the Niger before Mungo Park was even born.

It was a mystery to the outside world until the Scottish explorer Mungo Park came across the river in June 1786.
