Siargao is a tear-drop shaped island in the Philippine Sea situated 196 kilometers southeast of Tacloban. It has a land area of approximately 437 square kilometres (169 sq mi). The east coast is relatively straight with one deep inlet, Port Pilar. The coastline is marked by a succession of reefs, small points and white, sandy beaches. The neighboring islands and islets have similar landforms. Siargao is known as the surfing capital of the Philippines, and was voted the Best Island in Asia in the 2021 Conde Nast Travelers Readers awards.
The island is within the jurisdiction of the province of Surigao del Norte and is composed of the municipalities of Burgos, Dapa, Del Carmen, General Luna, San Benito, Pilar, San Isidro, and Santa Monica.
The first recorded sighting by Europeans of Siargao Island was by Spanish navigator Bernardo de la Torre on board of the carrack San Juan de Letrán in 1543 when attempting to return from Sarangani to New Spain. It was charted as Isla de las Palmas (Palm Island in Spanish).
On December 16, 2021, Typhoon Rai struck the area as a Category 5 super typhoon. It left the island devastated, with many buildings damaged or demolished. It caused ₱20 billion ($400 million) in damages.
