Its terrain is rolling plains suited for ricelands and its mountainous areas are best suited to coconuts, bananas and other crops which the people derived thir income. The boundaries of Lopez touches the municipalities of Calauag, Guinayangan, Buenavista, Catanauan, General Luna, Macalelon and Gumaca.

Once a part of municipality of Gumaca, Lopez has undergone many changes since it decided to be independent of its mother town. Then known as Talolong, it was not spread from Moro pirates that raided and plundered the villages along the shorelines of Lucena Bay. Sometimes in 1795, the Spanish Priest of Gumaca appointed Don Francisco de San Jose as Teniente Mayor of Talolong to take charge of repulsing the plunderers and raiders.

With peace restored, tha place attracted several couples from Gumaca and among them was Mateo Lopez of Tayabas to make a settlement in the place. As time went by, more and more people flocked to the site of the new settlement and Don Mateo Lopez, who then noted as the leader or "Cabeza de Barangay" of this group of prisoner settlers realized the need of placing this newly founded settlement on its own feet.
