Here are well-regarded luxury wellness resorts in Sri Lanka, grouped by region with what makes each special and practical notes to help you pick. I searched the latest resort webpages and recent travel coverage when compiling these. (If you’d like, I can narrow by dates, budget, or travel region.)

South coast / Tangalle / Galle area

• Amanwella (Tangalle) — Ultra‑quiet, minimalist beachfront resort with a long pool, open‑air yoga on the beach, in‑suite and beach treatments, and meditation sessions with local monks. Best for couples seeking privacy and low‑key luxury with yoga + spa focus. (Aman.com)
• Anantara Peace Haven Tangalle — Large resort with an award‑winning Anantara Spa offering Ayurvedic therapies, multi‑day wellness programmes (sleep, detox, fitness), plus gym, yoga and healthy dining options. Good for travellers who want a full spa programme with resort facilities. (Anantara.com)

Ayurvedic specialist resorts (classic therapeutic retreats)

• Barberyn Ayurveda Resorts (Barberyn Reef / Barberyn Waves / Barberyn Sands) — Family of clinics/resorts focused on authentic, physician‑led Ayurvedic treatment plans, daily yoga/meditation and diet‑based healing. Ideal if you want a medical/therapeutic Ayurvedic detox or longer treatment course. (barberynresorts.com)

Hill country / Kandy area

• Santani Wellness Resort (near Kandy) — Boutique, design‑forward wellness retreat on a former tea estate with personalized wellness programmes, Ayurvedic treatments, thermal facilities (steam/sauna/salt bath), tailored meals, daily yoga and guided nature walks. Strong choice for a wellness‑first escape amid cool hill‑country scenery. Recent coverage notes new villas and continued design focus. (santani.com)

Other notable luxury properties with strong wellness offerings

• Aman and Anantara are examples above; many five‑star beachfront hotels (e.g., some in Mirissa, Bentota, and Kalutara) offer spa programmes and Ayurvedic doctors — check each resort’s spa and Ayurveda centre for details and resident doctor availability. (See Amanwella / Anantara pages for examples.) (Aman.com)

Quick practical tips

• Best timing: South & west coast (Galle, Tangalle, Bentota, Mirissa) is generally best November–April; east coast (Arugam Bay, Trincomalee) is best May–October. Check the specific region’s monsoon season before booking. (thetimes.co.uk)
• Ayurveda stays often recommend 7–14+ nights for meaningful results; many resorts require a medical consultation on arrival and will tailor your programme. (barberynresorts.com)
• Price brackets: luxury wellness resorts range from upper‑upscale (Anantara, Amanwella, Santani) to more affordably priced authentic Ayurveda centres (Barberyn). Rates vary by season and programme length—ask for package pricing (detox/ayurveda/yoga) which often includes treatments and meals.
