Notes and quick tips

• “Eco‑friendly” can mean different things (energy/water saving, local sourcing, waste reduction, habitat protection, certifications). If a specific practice matters to you (solar power, plastic-free, certified carbon‑neutral, organic food, or wildlife protection), I can check each hotel’s current policies and certifications.
• I only pulled a quick set of sources just now; let me know if you want me to:
  • check up‑to‑date sustainability certifications and recent guest reviews for any of these properties,
  • find additional boutique eco options in the Bentota / Beruwala / Kosgoda area, or
  • compare rates/availability for your travel dates.
