Beach guide

Porto do Seixal beach

Dark sand that nobody imported, on the north coast, free to enter, with lifeguard service listed for the season. It is the answer to “where is the real black-sand beach?”.

Checked against the portaria and the municipality’s own pages on July 26, 2026.

Wet black sand reflecting a grey sky at Seixal, small waves running up the beach, a stone breakwater with a striped beacon to the left and a steep green cliff dropping into the sea on the right.

What it actually is

Surface
Natural dark sand
Municipality
Porto Moniz

The sand arrived by itself. On an island this young and this volcanic, that is the rare case.

A short bay under green cliffs, with waterfalls coming off them after rain. The sand is volcanic and it got here by itself, which on this island is rarer than the golden sand everybody photographs.

No Blue Flag for 2026. A flag is an application as much as an award, so a beach without one has not necessarily failed anything.

What the state says about it

Annex IV of Portaria n.º 204-A/2026/1 lists it as a designated bathing water, with a 2026 season running June 1, 2026 to September 30, 2026.

It appears in the “praia de banhos” column: lifeguard service is listed in the published documentation, not confirmed live.

Even where the documentation lists lifeguard service, this does not confirm a lifeguard is present when you visit. Always check on arrival.

Getting there

It sits in the concelho of Porto Moniz, which is how the portaria files it.

We print no bus route for this one. Route numbers are published here only for the four destinations checked against the operator’s own guides, and this is not among them.
