The Park Behind the Wild Beach
Praia da Adraga looks untouched: cliffs, sea caves, a reef point break, one restaurant, no boardwalk. The land immediately behind it is not untouched. It is the site of an active, multi-year ecological restoration project — the Parque Ecológico da Adraga e Praia Grande — and understanding what that project is, and is not, changes what "wild" means at this beach.
How the land was acquired
In 2021 Sintra's municipal council paid €500,000 for 54.6 hectares of coastal land between Praia da Adraga and Praia Grande. The seller was Cintra – Urbanizações Turismo e Construções, a now-bankrupt development company; the land had sat in that company's hands before the council stepped in. A January 2025 press report confirmed the deal and the project it enabled: a partnership between the municipal council, the Aga Khan Trust for Culture, Portugal's Institute for Nature Conservation and Forests (ICNF), the Portuguese Environment Agency (APA), and the Lisbon and Tagus Valley regional development commission (CCDR Lisboa e Vale do Tejo). A municipal technician said the park could eventually grow to 67 hectares with further acquisitions.
What condition the land was in
Before restoration work started, invasive exotic plants covered about 63% of the site, and only three of its habitats were rated in good conservation condition. That is the baseline the numbers below have to be read against. The council's own survey found 14 natural habitat types on the land — about 16% of every habitat type identified anywhere in Portugal, six of them under EU protection — plus 199 recorded plant species (25 invasive exotics, 34 rare or threatened natives) and more than 200 recorded animal species. A 2022 marine monitoring campaign off the same coast, fed by coastal upwelling, identified around 300 species, from algae to marine mammals.
The work itself, and who's doing it
Restoration crews have directly intervened on 17 hectares so far, using nature-based solutions tailored to each habitat rather than one blanket treatment. Some of that work has come from volunteers: the 2025 Ubuntu Fest Sintra brought about 320 participants — children, young people and educators from 12 schools in the county — out to clear invasive plants, and that single effort removed roughly 1.5 tonnes of hottentot-fig and 3 tonnes of carpobrotus ground-cover.
Phase one of the official project, due by 31 July 2025, covered clearing 35% of the northern area and laying three kilometers of marked trails. Phase two, running from August 2025 to 31 December 2027, is meant to clear the remaining zone, finish the trail network, and add observation points, rest areas, and an environmental interpretation center. A 13 January 2026 update from Público confirmed the project was still under way and still on track for the end of 2027. Officials have said the park can be visited before it's finished, but that full ecological recovery — not just clearance, but the habitats actually returning to a healthy baseline — will only be complete after ten years.
The deeper history under the restoration
The land carries more than recent history. Paleolithic tool sites were identified along this stretch of the Sintra coastline in the first decade of the 20th century by Henri Breuil and Georges Zbyszewski, who recovered chipped quartz, quartzite and flint tools from the Middle Paleolithic — roughly 300,000 to 36,000 BC — from red-earth ravines at the site. Nearby, on the cliff face of the adjacent Praia Grande do Rodízio — not on Adraga's own sand — 11 tracks of 51 dinosaur footprints and 15 isolated tracks survive from roughly 125 million years ago; signs there warn the cliff-top footprint path is closed for unstable cliffs, with a fine threatened for trespassers. Both finds belong to the shared protected coastline the park now covers, not to Adraga's beach itself.
The whole park falls inside the UNESCO-listed Sintra Cultural Landscape's special protection zone, and remains of the Roman villa of Santo André de Almoçageme survive near Almoçageme village next door — a reminder that people have been present on this exact stretch of coast, on and off, for roughly 300,000 years.
What this means if you're standing on the beach
None of this is hidden from a visitor, but none of it is obvious either. Walk up from the sand onto the cliff paths today and you are walking through a construction site for an ecosystem, not a finished nature reserve: some trails are new, some observation points don't exist yet, and most of the 54.6 hectares have not yet had the 17-hectare treatment applied to the rest. The council calls the finished product an ecological park. It might be more accurate to call it a decade-long repair job on land that a private developer's bankruptcy left derelict, and that the public then had to pay €500,000 to actually protect.
The beach itself — the sand, the point break, the Pedra de Alvidrar, the Fojo — was never for sale and isn't part of this project. But the backdrop that makes Adraga feel remote and wild is being actively managed, on a public schedule, by five institutions, one hectare at a time. The next time someone calls this coastline untouched, the more accurate word is unfinished.
