Here’s a curated list of widely regarded five‑star / luxury hotels across Sri Lanka, grouped by region so you can pick by location and travel style. I’ve included a one‑line highlight for each and a reputable source for the pick.

Colombo (city / business)

• Shangri‑La Colombo — modern 5★ on Galle Face with ocean views and extensive facilities. (en.wikipedia.org)
• Taj Samudra, Colombo — longstanding luxury seafront hotel popular with business and diplomatic travelers. (en.wikipedia.org)
• Cinnamon Grand / Cinnamon Lakeside — large full‑service 5★ hotels near the commercial district (great for dining/conference). (luxury-hotels.com)

South coast & Galle

• Amangalla (Galle Fort) — intimate, heritage five‑star inside the UNESCO Galle Fort (historical charm). (en.wikipedia.org)
• Jetwing Lighthouse (Galle) — Geoffrey Bawa‑inspired coastal property overlooking the Indian Ocean. (en.wikipedia.org)
• Cape Weligama (Weligama) — high‑end cliff‑top resort with dramatic sea views and villas (great for romance/families). (widely listed among top luxury south‑coast hotels). (luxury-hotels.com)

Cultural Triangle & Central Highlands

• Heritance Kandalama (near Dambulla / Sigiriya) — iconic hotel set into the landscape with panoramic rock/jungle views; often ranked among Sri Lanka’s best. (tripadvisor.com)
• Ceylon Tea Trails (Nuwara Eliya area) — luxury bungalow suites on working tea estates — top choice for a “tea country” experience. (commonly listed among Sri Lanka’s boutique 5★ options). (luxury-hotels.com)

Boutique / ultra‑luxury escapes

• Amanwella (Tangalle) — small Aman property with minimalist design, private beach and high service standards (excellent for a calm luxury stay). (en.wikipedia.org)
• Cape Weligama / Anantara / Anantara Peace Haven (various properties on the island) — several internationally branded ultra‑luxury resorts across the coast (great for resorts & spas). (luxury-hotels.com)

Notes and tips

• “Best” depends on what you want: Colombo for city/business, Galle/South for beaches and design hotels, Cultural Triangle for nature/history, Hill Country for cooler tea‑estate stays.
• Many top hotels are small/seasonal or sell out during peak season (Dec–Mar south coast, Jul–Aug for hill country). Book early for holiday periods.
• If you want specific recommendations (by date, budget, or region — e.g., best for families vs. honeymoon vs. architecture), tell me your travel dates and preferences and I’ll refine choices and check availability/pricing.

If you’d like, I can:

• Narrow this to a “top 5” based on your travel style, or
• Pull current rates/availability for particular hotels on your travel dates.
