Boca do Inferno
A dramatic sea cave and cliff formation where Atlantic waves crash into a collapsed grotto, creating explosions of spray. Free to visit, a short walk west along the coast from the town centre.
Town in Portugal
Cascais
4 things to see
Just 30 minutes from Lisbon by cheap commuter train, Cascais pairs Atlantic beaches and the dramatic Boca do Inferno sea cliffs, both free to reach, with a polished but accessible town centre that is pleasant to wander at no cost. Budget travellers use it as a beach base for Lisbon exploration, especially when city-centre accommodation prices spike in high season. The hilltop palaces and gardens of Sintra are a short, cheap onward hop, so the two pair well in one trip. Shoulder season keeps the warm coast without the peak-summer rates.

Things to do in Cascais
What each one costs, where the cost is known.
Casa das Historias Paula Rego
A striking terracotta museum designed by Eduardo Souto de Moura, dedicated to the work of Portuguese artist Paula Rego. Entry is free and the building itself is an architectural highlight of Cascais.
Cascais Old Town
A pedestrianised centre of cobbled lanes, pastel-coloured houses, and fish restaurants between the marina and the citadel. Free to wander, and the train from Lisbon costs under three euros each way.
Praia da Rainha
A tiny sheltered beach tucked between cliffs in the centre of Cascais, once reserved for the queen. Free access and calm water, though it fills fast in summer due to its small size.
