Maré Verde · Western Atlantic Coast, Portugal

Water is
not the destination.

It is where we remember who we are.

Women who chose this coastline — and in choosing it, made it theirs. Science that belongs to the community. Tourism that heals what it touches.

The Foundation
01 / Conservation

The Ocean as Commons

We train women as marine monitors and citizen scientists, mapping the invasive alga Rugulopteryx okamurae along Portugal's Atlantic coast. The ocean is everyone's home, not a resource to exploit — the Blue Commons, in economist Guy Standing's words.

02 / Community

Dignity Before Impact

Our monitors are trained, paid professionals — not volunteers. Gender equity is not a project add-on. It is the architecture of the project.

03 / Blue Mind

Water as Medicine

Here, you're not just a visitor — you take part. Alongside our guides, you monitor invasive species and contribute real scientific data, while the ocean calms your nervous system. This is regenerative tourism: personal healing and real action, on the same tide.

What We Believe

The science of Blue Mind is already inside us.
We just forgot to listen.

  • The ocean is not a backdrop for wellness retreats. It is an active participant in human healing — neurologically, emotionally, spiritually.
  • Conservation and wellbeing are the same work. You cannot heal people in a broken ocean. You cannot protect an ocean that people do not love.
  • The women who choose this coastline — immigrants, newcomers, young women who stayed — bring perspectives no university has yet measured.
  • Every visitor who kneels in the water to identify and log an invasive alga is not a tourist. They are a citizen of the ocean.
  • Regenerative means that the act of healing creates more healing. Tourism that restores. Revenue that stays. Science that belongs to the community.

Practical Info

Frequently Asked Questions

What should I bring?
Closed, non-slip shoes, sunscreen, a hat, and clothes that can get wet. We provide all scientific equipment.
Do I need to know how to swim?
No. Rock Pooling and Scientist for a Day don't require swimming — just walking in low-tide areas.
What's the minimum age?
From age 8, always accompanied by an adult. Children aged 8–15 pay half price.
What happens in bad weather?
Outings depend on tide and safety conditions. If we cancel due to weather, we reschedule at no extra cost.
Is it accessible for people with reduced mobility?
We're working to make more experiences accessible — please contact us directly to discuss your situation.
How do I book?
Through the "Reserve your spot" button on each experience, which opens a direct email to us.
Summer 2026

The first outings are happening now.
Be part of it from the beginning.

We are launching our first pilot outings in Summer 2026. A small group of people will be the first to become citizens of this ocean. Leave your email and we will reach you before anyone else.

Already in the Water

A consortium built on real commitment — and a community already in motion.

Maré Verde is not waiting to begin. We are already in the water — alongside women of different origins and generations, conducting field outings to document invasive species and building ocean literacy from the ground up. Community engagement is not a future milestone. It is happening now.

Our formal consortium brings together municipal authorities and a research university committed to this coastline.

For Organisations & Investors

This is the right moment to become part of it.

Maré Verde operates at the intersection of marine conservation, regenerative tourism, and community equity on Portugal's Atlantic coast. We are building partnerships with organisations that share our mission.

If you are an investor, foundation, impact fund, accommodation partner, or organisation working at the intersection of ocean health and social equity — we want to talk.

Meet Leonor

My path here began at a tide pool. As a child I would sit at the water's edge watching the small creatures, the shells, the colours in the sand, feeling completely at home. That peace — that sense of returning to oneself — is the thread that runs through everything Maré Verde is trying to offer.

Years later I learned to dive in Asia. Sailed the Atlantic after becoming a mother. And what I understood, slowly, is that the ocean never changed me. It kept confirming me. Across every continent, every version of my life — the same breath: slow, deep, surrounded by water.

Maré Verde was born from that certainty, built on the margins of my life — between a full-time job and raising my daughter.

"Blue Mind has always been here — in the rock pools of every child who grew up on this coast, in the hands of the women who mended nets and gathered shellfish, in the silence of a dawn sail on the Atlantic. Today it lives in the hands of other women who chose this coastline — surfers who stayed, immigrants who arrived, young women who didn't leave.

We are simply giving it a name, a structure, and a home."
Leonor Salgueiro · Founder, Maré Verde

Come to the water.

Maré Verde is a movement still being built — and that is precisely the right moment to become part of it. People don't come back out of duty — they come back because they belong. You protect what you love, and you learn to love what you protect — the ocean, this coast, and, somewhere in between, yourself. In 20, 50 years, we want this still to be true. The Western Atlantic coast of Portugal is waiting. So are we.
