The largest World War II naval and military facility in the Pacific behind Pearl Harbour, the clear waters of Santo hold a treasure trove of sunken ships and aircraft, making it one of the best wreck diving hubs in the South Pacific. 

During World War II, the sleepy island of Santo was transformed by the United States Armed Forces into the largest Allied military base in the South Pacific behind Hawaii’s Pearl Harbour. Codenamed Base Button, Santo hosted over 500,000 servicepeople throughout the war years – nearly 10 times more people than the entire population of Vanuatu at the time. The legacy of this era can be explored at many places above and below the water in Santo today.

With World War II wrecks to dive, dreamy blue holes to paddle to, rivers you can float long and natural wonders to explore in the island’s tropical rainforest, Santo was made for adventure.
