Hidden Coves and Secret Beaches
Beach & Coast
Beyond the well-known resort beaches, the Algarve harbours dozens of tucked-away coves that reward those willing to walk, scramble or take a boat. These hidden spots are carved into the limestone and sandstone cliffs that define the central and western coastline, and many are only accessible at low tide or via narrow cliff paths. They offer a quieter, more intimate experience of the Algarve coast, though they generally lack the facilities found at larger beaches.
Praia da Mesquita, near Carvoeiro, is one such gem. Reached by a rough path from the clifftops east of the village, this tiny cove sits between towering rock stacks and is often empty even in August. The sand is coarse and mixed with pebbles, and the water is deep enough for swimming close to shore. There are no facilities whatsoever, so visitors need to bring water, food and sun protection. The path down is steep and unmarked, requiring sturdy footwear and a reasonable level of fitness.
Praia do Submarino, also near Carvoeiro, takes its name from a rock formation that resembles a submarine conning tower. This sliver of sand is almost completely enclosed by cliffs, creating a natural amphitheatre effect. At high tide the beach disappears entirely, so timing a visit around the tides is essential. The Carvoeiro boardwalk passes above, and a set of carved steps leads down to the sand. Snorkelling here is excellent, with clear water and rock formations that shelter small fish, octopus and sea urchins.
Further west, the coastline around Benagil is famous for the Benagil sea cave, a cathedral-like cavern with a collapsed roof that lets sunlight pour onto a small internal beach. The cave can only be reached by water, either by kayak, paddleboard or swimming from the adjacent Praia de Benagil. Tour boats also visit, though they cannot land. The cave has become heavily visited in recent years, and authorities have introduced boat traffic management during peak season. Early morning visits by kayak, setting off before nine, remain the best way to experience the cave without crowds.
Praia da Marinha, consistently rated among Europe's finest beaches, is not exactly secret but its layout creates pockets of privacy. The main beach sits at the base of a steep staircase, but those who explore eastward along the waterline at low tide will find a series of small coves separated by rock arches and pillars. These natural alcoves feel completely secluded, with warm shallow pools and dramatic cliff scenery. The snorkelling along the base of the cliffs is outstanding, with visibility often exceeding fifteen metres.
On the west coast, the beaches become wilder and less visited. Praia da Arrifana, set in a dramatic cliff-ringed bay near Aljezur, attracts surfers but has a quieter northern section accessible by walking along the sand at low tide. Praia do Barranco, also near Aljezur, is reached by a steep descent through a wooded valley and feels genuinely remote. The Atlantic swells here are stronger than on the south coast, and swimming requires caution, but the landscape is spectacular.
Praia da Afurada, tucked between Portimao and Ferragudo, is a local favourite that few tourists discover. Accessed through the small fishing village of Afurada on the eastern bank of the Arade river, this sheltered beach faces the river mouth rather than the open sea, making the water calmer than neighbouring ocean beaches. The village itself has several excellent fish restaurants where the catch is grilled on charcoal outside the front door.
A few rules of thumb help when seeking hidden coves. Always check tide times before setting out, as many small beaches are submerged at high water. Wear proper shoes for cliff paths, as the sandstone crumbles easily. Carry water, as there are no kiosks at remote coves. Tell someone your plans if venturing to isolated spots alone. And resist the urge to share exact GPS coordinates on social media, as overcrowding has already diminished the appeal of several formerly quiet beaches.
