Surigao del Norte is the second northernmost of the Mindanao provinces and is an important transportation hub between Visayas and Mindanao. Numerous ferries cross the Surigao Strait between Surigao and the island of Leyte carrying vehicles and passengers between Liloan in Southern Leyte and Surigao City.

The area of Surigao del Norte was once part of an ancient district referred to as "Caraga" during the Spanish colonial period named after its chief inhabitants, the Caraga tribe or Caragans who were largely concentrated in a settlement called Caraga. The ancient district of Caraga, which was established in 1609 comprised all of the present day provinces of Surigao del Norte, Dinagat Islands, Surigao del Sur, the northern part of Davao Oriental and eastern Misamis Oriental. The seat of government was at Tandag until it was transferred to the town of Surigao in 1848. Six Spanish military districts were established in Mindanao in 1860 and the areas of present-day Surigao del Norte, Surigao del Sur, Dinagat Islands, Agusan del Norte and Agusan del Sur (collectively called Agusan back then), including the territory lying between present day Butuan and Caraga bays, formed the third district called the "East District" which was changed in 1870 to "Distrito de Surigao". By the end of the Spanish rule in 1897, Agusan had been organized as a single politico-military comandancia named "Butuan", within the administrative jurisdiction of Distrito de Surigao.

Distrito de Surigao became a chartered province on May 15, 1901 (Philippine Commission Act 127). The territorial expanse of the Surigao province was further reduced in 1907 when the politico-military commandancia of Butuan, then a sub-province of Surigao, was created into a separate province and officially named it Agusan with present-day Butuan as its capital.[4]

Dinagat Islands had been a part of the First District of Surigao del Norte until becoming a province on its own on December 2, 2006, with the approval of Republic Act No. 9355,[7] the Charter of the Province of Dinagat Islands, in a plebiscite. Between February 2010 and March 2011, the islands were part again of Surigao del Norte after declaring RA 9355 unconstitutional by the Supreme Court, then were reinstated as a separate province.

The province, with an area of 1,972.93 square kilometres (761.75 sq mi),[1] comprises the mainland situated at the northeastern tip of Mindanao and several offshore islands, the largest of which include Siargao and Bucas Grande. The mainland is generally mountainous.[4]

The province has many caves and tunnels in its islands. Some are half-submerged in water most of the time and could be accessed only during low tides like the Sohoton Cove at Bucas Grande Island.

Its biggest islands are usually mountainous and rich in minerals. Nonoc Island has one of the world's largest deposits of nickel. The smaller ones either rest on sand and gravel or have a limestone base bonded by boulders, reefs and sandbars. Some islets which include those in Del Carmen in Siargao Island are a cluster of rock formations jutting out from the sea covered with shrubs and coconut trees.

Surigao is home to the Mamanwa ethnic tribe. Their dances are showcased in a local festival called "Bonok-Bonok", held at the feast of San Nicolas de Tolentino which is held annually on September 10. The Bonok-Bonok depicts the native folks' merry-making to show gratitude to God for bountiful harvest and good health.

A collection of ancient archaeological diggings like burial coffins, jars and Chinese ceramics unearthed in Panhutungan, Placer is on public display at the Surigaonon Heritage Mini-Museum located at the Boulevard in Surigao City.

Mangroves are the major vegetation in the coastal areas of the province, which form interminable marine forests covering 175 square kilometres (68 sq mi) along the coasts of the mainland and the islands of Siargao and Bucas Grande. The province is host to a variety of marine ecosystems like the lush seagrass beds and coral reefs which are relatively healthy and intact, supporting a rich diversity of marine flora and fauna.

Over 23 different species are caught the whole year round. Marlin, tuna, lapu-lapu, mollusks, crabs, even squids, stingrays and octopuses can be bought from fish vendors and fishermen.

The unique "magcono" (ironwood) forests of Surigao del Norte are one of the watersheds most productive resources. By its nature, it is slow growing and adapted to a mineralized soil.

Surigao City, the provincial capital, is dubbed as the "Gateway to Mindanao". The ferry landing terminal in Lipata links Mindanao to Luzon through Eastern Visayas. It annually showcases its distinct cultural heritage through the Bonok-Bonok Maradjao Karadjao Festival.

On the northern side of the province are Siargao and Bucas Grande Islands, known for their long stretch of sugar-fine beaches, vast mangrove forest, and deep waters teeming with marine life.

The Panhutongan and Amoslog archeological excavations in Placer would give a glimpse of the origins of the province and its people.
