What is Porto de Santa Iria?

Geology & Volcanology
At Porto de Santa Iria, you can see pieces of evidence of past volcanic eruptions with your bare eyes and feel them with your hand. Indeed, to reach the water, you must pass by old lava that has dried a long time ago, creating a natural pool surrounded by lava rock and interesting geological formations, such as the islets found in the ocean.
All this comes from the Volcano of Lagoa do Fogo, whose last eruption was in 1543. It is still active and could erupt at any time, but don’t worry – we have scientists monitoring the Azorean volcanoes.
History & Geography
Porto de Santa Iria has always been a fishing harbor, but nowadays, you won’t see as many fishing boats. Now, some boats are doing excursions to explore the nearby caves and cliffs, and locals use this wonderful place to swim and sunbathe.
The small harbour of Santa Iria is located in Ribeirinha, in the county of Ribeira Grande, on the north coast of São Miguel.
Fauna & Flora
Between the impressively high green cliffs and the magnificent Atlantic Ocean, Porto de Santa Iria is rich in marine wildlife. The Azores’ archipelago is a paradise for cetaceans, fish, and many aquatic species.
Here you have a beautiful, small spot to jump off lava rocks or the tiny harbor made of cement. But don’t forget your mask and tuba, you won’t regret it! We might not have corals in the Azores, but fish are colorful here.
What to Do at Porto de Santa Iria

Swim in the Atlantic Ocean
While Porto de Santa Iria itself does not have a sandy beach, you can swim at an authentic Azorean natural pool that used to be a fishing harbor. It might be different from the regular beach experience, but there is nothing better than living like a local! Those are probably the clearest and most luxurious waters you will find around.
Please note that this is not an official bathing area, so there is no lifeguard, changing rooms, toilets, café, or other facilities available. If the weather or sea conditions are not great, we do not recommend taking a chance swimming there, especially if you are not comfortable in the ocean.

Plan Your Visit to Porto de Santa Iria

Best Time to Visit

However, if you want to avoid strong sun rays, you can always come at any time to this incredible place. It is open at any hour of the day and night, however, it is not recommended to come at night because there are no lights around.

How to Get to Porto de Santa Iria
Porto de Santa Iria is only 10 minutes away from the city of Ribeira Grande by car, towards Ribeirinha. Follow the directions towards Ponta do Cintrão and stop your car near the straight cement road on the right.
You cannot reach the harbour by car, or public transportation. You will need to walk for 5 minutes down to Porto de Santa Iria. It is quite a steep way down, and then up when you want to get back to the car. But it is all worth it!
What to Bring
Walking on lava rocks to get to the ocean can be uncomfortable for some people. Bring water shoes to walk safely on the rocks. Sunscreen is always very important to bring in the Azores, because of the strong sun rays. As there is no sand, you will not be able to bring a beach umbrella.
A mask and tuba are a must-have, if the sea conditions are nice. And always have some snacks and water with you!
