Here are well-known Sri Lanka hotels/resorts that offer villa-style accommodation suitable for families (across the south coast, cultural triangle, east coast and safari areas). I’ve listed a short note about the family-friendly villa option and included sources you can check for details and booking.

• Cape Weligama (Weligama / South Coast) — cliff-top resort with multiple villa types and family-appropriate interconnecting/ multi-bedroom villas; villas are arranged in small garden “clusters” with shared/private pools and easy access to family activities (whale watching, snorkeling). (smartflyer.com)

• Amanwella (Tangalle / South Coast) — luxury resort offering private pool suites and ocean/ garden pool suites; calm, spacious accommodation and high service levels that work well for families wanting privacy. (nearfarmag.com)

• Anantara Peace Haven Tangalle Resort (Tangalle / South Coast) — offers beach and pool villas, family activities and kids’ programming; villas with private pools and direct beach access make it a popular family choice. (fivestaralliance.com)

• Uga Ulagalla (Anuradhapura / Cultural Triangle) — a villa-only property with one- and two-bedroom private pool villas (including larger family villas), good for families combining wildlife/culture with private space. (ugaescapes.com)

• Dolphin Beach Resort (Kalpitiya / Northwest) — family tents and family-oriented accommodation options on the peninsula; appeals to families who want a beach-and-nature experience (dolphin/kite-surfing area). (en.wikipedia.org)

Notes and tips

• Villa definitions vary: “villa” can mean a standalone private pool villa, a two-bedroom suite, or a cluster of suites sharing a private pool. Check exact room layouts, maximum occupancy and whether extra beds/cots are available before booking. (booking.com)
• If you plan inter-island / multi-region travel (south coast + Cultural Triangle + Yala or east coast), look for resorts that can arrange transfers and kid-friendly excursions (many of the properties above offer family activities and child services). (smartflyer.com)

If you’d like, I can:

• Narrow choices by region (south coast, east coast, cultural triangle, Yala), budget (luxury vs mid-range), or specific family needs (interconnecting rooms, kids’ club, private pool, baby/child services), and return options with direct booking pages and approximate price ranges.
