Parque Regional de Sierra Minera & Calblanque Border
The rugged hills that frame Mazarrón to the east are part of a protected natural corridor linking the Sierra Minera with the Calblanque Regional Park — a landscape of abandoned mine workings, wild rosemary scrub and hidden coves that sees a fraction of the visitors who flock to the coast below. It is one of the last genuinely wild corners of the Murcian coastline.
Hiking the old mining trails
Signed walking routes from the village of Perín lead up through the sierra past the rusted headframes and ochre spoil heaps of 19th-century silver and lead mines — a haunting industrial archaeology lesson set against panoramic sea views.
The 8 km Ruta de las Minas loop is manageable in two to three hours at an easy pace and rewards walkers with views stretching from Cabo Tiñoso all the way to the Isla de Adentro off Puerto de Mazarrón.
Secluded coves below the sierra
Where the sierra meets the sea, a series of tiny, roadless calas — including Cala del Mojón and Cala Cerrada — can only be reached on foot or by kayak, which keeps them beautifully uncrowded even in August.
The water over the rocky seabed here is extraordinarily clear, and the lack of sand means snorkelling visibility can exceed 10 metres on calm days — bring a mask and fins rather than a beach umbrella.
