Great — here are highly recommended luxury resorts in Sri Lanka that focus on wellness, Ayurveda and spa programs, grouped by region with a short note on what makes each special and a source you can check for details.

Cultural Triangle / Inland (nature + Ayurvedic clinics)

Heritage / Architecturally notable

• Heritance Kandalama (near Dambulla/Sigiriya) — Geoffrey Bawa‑designed resort with a well‑regarded spa and proximity to jungle and heritage sites; good for combining architecture, birding and spa treatments (Six Senses/Heritance spa offerings vary by season). (letsgomelo.com)

Quick planning tips

• Programs vs single treatments: if you want a true wellness reset, book a multi‑day Ayurvedic or detox programme (3–7+ nights) — many resorts require a pre‑arrival consultation with their resident Ayurvedic doctor. (Anantara.com)
• Best times: south coast and hill country are pleasant December–March and May–September respectively (weather varies by coast). (If you want exact seasonal guidance for specific dates, I can check current climate averages.)
• Transfers: allocate time for road transfers (Colombo → southern beaches ~3–4 hrs; to Cultural Triangle ~4 hrs); some resorts offer domestic plane or helicopter options. (luxus-reiseprofi.de)
• Ask about inclusions: resident Ayurvedic doctor consultations, yoga classes, daily juices or Ayurveda cuisine, and how many treatments are included in package rates. Compare packages (wellness vs. room‑only) before booking. (Anantara.com)

If you’d like, I can:

• Narrow this list to 2–3 resorts that suit a specific travel window, budget or vibe (silent retreat vs. active wellness), and check current package availability/prices for your dates.
• Pull direct links and contact info for any of the properties above.
