Serra de l'Espina is a limestone mountain chain located at the north-eastern end of the Iberian System. It connects the Ports de Tortosa-Beseit mountain massif with the Catalan Pre-Coastal Range.[1]
The Serra de l'Espina ridge's highest point is L'Espina (1,181.6 m).[2] Other high peaks are Mola Carrascosa (1.025 m), Cap de la Faixa Blanca (1.023 m), Tossal de Montclí (960 m) and La Moleta d'Alfara (812 m).
On the eastern side of the range are some visible barren patches, devoid of vegetation owing to high winds, the very large Rases del Maraco, or Les Rases, at the southern end and Erms de Canduca further north. Other noteworthy places are Solana de les Feixes, the Cova dels Adells karstic cave and the ruins of Mas del Roig, an ancient farmhouse.
The Serra de Paüls mountain range is located to the north of this range.
