Who was the first European explore

This is a hard question, do you mean a specific time?

Europeans have been exploring lands around them before our time (1000 BCE) such as the Phoenicians (but you might argue they were not originally European), who might have travel led to Britain at that time.

Probably the first well - known European explorers were the Vikings, who settled Iceland, Greenland (you mightname Erik the Red, who went to Greenland in 10th century) and even reached America.

You may need to be more specific because there are many European explorers.
