The Municipal Natural Area "Serra de Quatretonda" extends through the northern part of the municipality of this town. Geographically, it belongs to the extreme north-eastern part of the Serra Grossa, a 60-km-long mountain range that stretches from the town of Font de la Figuera, to the southwest, to the town of Pinet, to the northeast, and which acts as a natural barrier between the districts of La Costera, on the northern slope, and the Vall d'Albaida, on the southern slope. The total area of the Natural Area is 1676,284 ha and the land is municipal property.
The average altitude is between 400 and 440 meters above sea level, reaching its highest altitude in the so-called Alt de l'Hedra, 672 meters high.
From the Geological point of view the Site is included within the zone of interference between the Prebatic and Iberian domain, characterized by a great structural complexity, in which no defined tectonic alignments appear. The structure that affects the Serra is the Pinet syncline, a fold of direction NO-SE to N-S produced by two large normal faults.
