The explorers who traveled farthest west were likely the Spanish explorers, such as Ferdinand Magellan, who led the first expedition to circumnavigate the globe in the early 16th century. Magellan's journey took him across the Pacific Ocean, reaching the Philippines before his death. Additionally, explorers like Sir Francis Drake and later American expeditions during the Age of Exploration also ventured into the far western territories of the Americas and the Pacific.
