The town of Quezon lies in the southernmost part of the little Island of Alabat which belongs to the province of Quezon, formerly Tayabas, one of the foremost provinces of the Philippines, because it was well known for its coconut plantations. The little island of Alabat is east of the Island of Luzon, separated from the mainland by Lamon Bay, with perhaps the same distance of none nautical miles to Gumaca, Hondagua and Calauag. There is a wall of mountains shutting off the Pacific Ocean in the east, the Gumaca mountains are in the west and the south is screened by the hills of Quezon. These hills and mountains diminish very much the force of winds. The current in the narrow channel made by the change of tides kept the Silangan Strait, about less than one kilometer in width, which connect the Lamon Bay and the Calauag Bat, always deep free from big rocks that endanger navigation. The land now comprising the town of quezon is sandy in the plains-that is best suited for coconut plantation. There are few hills and little rivers and no irrigation system which account for the poor rice harvest every year. The mountains and hills which are once forested before, are cleared and planted with coconut trees and different crops, except for a few which are not fitted for cultivation.

According to the records kept and filed by the ffice of the Municipal Treasurer, the estimated land area is 10,670.44 hectares. But, this figure will surely increase when the Virgo surveying and Builders Corporation, who was awarded the public land subdivision survey of PLS-1065-D, Quezon, Quezon on May 12, 1972, has finished thir survey. And there was a joint meeting held by the Municipal Councils of Quezon and Alabat at the Hall of the Barrio Health Center, Barrio of Buenavista, Alabat, Quezon on September 30, 1972, wherein Resolution No. 1 has been approved , establishing a new municipal boundary lines between the tows of Quezon and Alabat, Province of Quezon, more or less described as follows:

"The first point is located between the Barrios of Mascariña and Buenavista and is 720 meters more or less from Cayas Creek following the edges of the shore of Lamon Bay on a Southast direction. The second point is 700 meters more or less from the junction of Buenavista Creek (Bicalin Creek) and Pinagcabocan Creek following the upstream of Bicalin Creek on the Northeast direction. The third point is one (1) kilometer more or less from Triangular Station Cliff (Mahiwagang Bato) situated at Barrio Villa Norte going on a Southwest direction. And the fourth point is the Triangular Station Cliff (Mahiwagang Bato)".

Besides, there, exist a foreshore land, which has been part of the sea before, this land, estimated at three hectares more or less is caused by the force of strong waves and by the presence of the cemented wharf constructed perpendicular to the town proper that the sand is kept little by little intact in the adjoining land. It is now mostly occupied and settled by the fishermen. The climate is warm. The rainy season starts when the northeast and westerly winds approach the month of June.
