As travel trends increasingly shift towards mindfulness, purpose, and environmental responsibility, sustainable tourism is no longer a niche — it’s the new standard.
With 83% of travellers stating that travelling more sustainably is important to them, Europe’s lesser-known eco-destinations are stepping into the spotlight.
According to new research from Accor and Natura 2000 — a network of protected areas across the EU safeguarding Europe’s most valuable habitats and species — the continent’s hidden green getaways are reshaping what sustainable travel looks like in 2025. From Portugal’s wild Atlantic coastline to Albania’s serene karst lakes, these destinations are proving that it’s possible to explore without leaving a heavy footprint.
Whether you’re hiking across Lithuanian wetlands or sailing beside Cyprus’ marine sanctuaries, these countries are making bold moves to protect their landscapes on land and at sea, ensuring they remain thriving for generations to come.
Here are some of Accor’s favourite under-the-radar green escapes to consider for your next conscious adventure:
Baie de Somme, France — Nature as Sanctuary
Designated as a Natura 2000 site, the Baie de Somme is a beacon for biodiversity preservation. From kayaking through peaceful salt marshes to seal-spotting along the coast, this area is perfect for slow, nature-first travel. It ranked 3rd in the Green Destinations Award 2024 – Destination Management, thanks to its commitment to protecting fragile ecosystems while delivering enriching visitor experiences.
Lagos, Portugal — Between Golden Cliffs and Wild Coves
Tucked away in the Algarve, Lagos is a model for coastal conservation. Its protected shoreline invites visitors to hike dramatic cliffs, swim in clear waters, and observe local biodiversity — all while supporting sustainable tourism efforts. It was recognised with the Green Destinations 2024 Award – Nature & Scenery for its outstanding natural preservation.
Miren Kras, Slovenia — Where Karst Meets Forest
Just a short drive from Ljubljana, Miren Kras blends ancient limestone caves with deep green forests. Its community-led sustainability approach has earned it the Green Destinations Award – Environment & Climate, offering visitors eco-friendly lodging, locally sourced food, and scenic, responsibly maintained hiking trails.
Castro Daire, Portugal — The Village That Preserves the Soul of Travel
Located east of Porto, Castro Daire is an authentic, rural municipality that invites you to slow down. Known for its cultural richness, traditional honey production, and biodiversity-rich landscapes like the Serra do Montemuro and Rio Paiva, it took 1st place in the Green Destinations Award – Culture & Tradition for its strong ties to heritage and nature.
Belsh, Albania — The Luxury of Simplicity
Roughly 60km south of Tirana, Belsh is a quiet gem set among karst lakes and olive groves, where life moves at the gentle pace of the seasons. Grounded in farming, fishing, and authentic hospitality, it placed 2nd in the Green Destinations Award – Culture & Tradition. Here, simplicity isn’t a sacrifice — it’s the luxury travellers are craving.
