How did the Vikings establish trade routes across the North Atlantic?

The Vikings established trade routes across the North Atlantic through their advanced shipbuilding and navigational skills. They used their longships, which were lightweight and had a shallow draft, allowing them to navigate through shallow waters and reach distant lands. They also utilized their knowledge of celestial navigation, using the sun, stars, and landmarks to guide their journeys. Additionally, the Vikings established settlements and trading posts along their routes, such as in Greenland and Iceland, which served as bases for their trade activities.
