Answer:
16,020 ft.
It is stunning that what most think of as a "tropical island" can contain a peak of over 16,000 feet, but such is the case. To put this in perspective, that is higher by far than any peak in the contiguous 48 states of the United States (topped by Mt. Whitney in California at 14,505 ft.). It is higher as well than any peak in the Alps or western Europe as a whole (topped by Mont Blanc at 15,782 ft.). It is by far the highest point on any island in the world, followed by Mauna Kea in Hawaii at about 13,800 ft. There are several additional peaks on the main island that tower over 14,000 feet.
