Lamon Bay is a body of water connecting the northern part of Quezon to the Pacific Ocean. It bounds the coastal towns of Atimonan, Gumaca, Plaridel, Lopez, and Calauag, and the islands of Alabat. It is a rich fishing ground and the home of various living corals. Most parts of the bay consist of gray sand, some parts are filled with rocks, and other living corals. It is gradually sloping to the extend that, during low tide, the water level is low enough to allow one to walk as far as five hundred meters from the shore. The beaches in the towns of Gumaca and Plaridel are sandy and ideal for swimming. In some parts of the bay, about ten feet from the beach front, are living corals. The town of Lopez has the best colonies of corals which are located just about15 minutes by boat from the shore. Lamon Bay is located at the northern part of Quezon.
