Toledo lies on Tanon Strait across from Negros Island and the city of San Carlos, Negros Occidental. Toledo City is home to the Philippines' largest copper mine, owned by Atlas Consolidated Mining and Development Corporation; concentrates from the mine are shipped from the port of Sangi near Toledo. Low-quality coal has also been mined in the area, but little coal is mined today. Important local crops include maize (corn) and coconuts.
