Beach guide

Porto do Seixal beach

Dark sand that nobody imported, on the north coast, free to enter and staffed through 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.

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, which is how the annex records that assistance to bathers is assured.

Neither of those is our judgement. It is which column the beach appears in.

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.
