Here are high-quality eco-friendly luxury stays within easy reach of Sigiriya (Cultural Triangle). I’ve listed each property’s distance to Sigiriya Rock, the main sustainability features, the style of accommodation, and a quick note on who each is best for.

1. Jetwing Vil Uyana — wetland eco-luxury (≈ 5–10 km / ~10–20 min from Sigiriya)

• Why stay: Built on a restored wetland/paddy mosaic, villas are raised over reed beds, marsh and paddies; strong biodiversity / birdwatching focus, nature trails, organic produce and on-site wellness. Ideal if you want a luxury stay that’s explicitly designed around conservation and wildlife. (jetwingeco.com)

2. Heritance Kandalama — landmark green architecture (≈ 18–25 km / ~30–40 min)

• Why stay: Geoffrey Bawa–inspired design that blends into the rock/reservoir landscape; long-established sustainability programs (water/energy management, recycling, community projects) and excellent views of the Cultural Triangle. Good if you want iconic architecture + eco-practices with easy access to Sigiriya and Dambulla. (cahayaharamain.com)

3. Kalundewa Retreat — small solar-powered eco-retreat (≈ 20–30 km / ~30–45 min)

• Why stay: Low-density luxury chalets set among lakes and paddy fields; strong farm‑to‑table program, large on-site organic gardens, significant solar generation (they advertise very high solar/renewable usage) and wellness offerings. Best for a secluded, slow-living wellness escape. (kalundewaretreat.com)

4. Ulagalla by Uga Escapes — countryside eco-boutique (≈ 40–50 km / ~50–70 min depending on route)

• Why stay: Boutique villas spread across extensive private grounds with an organic garden, solar and water-treatment initiatives, local community engagement and nature activities (horse riding, cycling, birding). A good option if you want private villa-style luxury on sustainable grounds and don’t mind a longer transfer. (ugaescapes.com)

5. (Smaller / more local options) Kuwera / Backwaters / boutique eco-lodges around Sigiriya (within ~10–30 km)

• Why consider: Several family-run eco-lodges and small retreats emphasize low-impact construction (mud-brick, natural ventilation), organic food, village experiences and community involvement — cheaper and very low‑impact while still comfortable. Good if you prefer local, community-led stays. (Examples and aggregator listings reference multiple local eco-lodges near Sigiriya.) (explorehiddensrilanka.com)

Practical notes

• Transfers: Sigiriya Rock is in the Cultural Triangle; most resorts offer airport transfers or can arrange private drivers from Bandaranaike International Airport (Colombo) or from Colombo/Kandy. Transfer times above are approximate by road and vary with traffic.
• Booking & questions: For current room types, exact availability, up-to-date sustainability certifications and rates (seasonal), check each hotel’s official website or a trusted booking platform before booking — I cited the hotel pages and sustainability pages above for each property.

If you’d like, I can:

• Compare nightly price ranges and sample room types for selected dates, or
• Build a 3–5 day sample itinerary from Sigiriya that pairs one of these eco-resorts with a Sigiriya climb, a Minneriya/Kaudulla elephant safari, and Dambulla caves.
