Short answer: Closest to Bangkok and easiest are Hua Hin–Cha-am (long beaches, safe towns); on the Andaman pick Khao Lak (gentle surf, family resorts) or Ao Nang (easy island tours); for an island near Bangkok choose Koh Samet (Rayong); on Samui, pick a quiet zone like Maenam or Choeng Mon.
The picks, ranked
Hua Hin
A safe seaside town near Bangkok with long beaches, water parks, markets and lots of family resorts — good year-round.
Cha-am (Phetchaburi)
A Thai family beach town with a long, gentle beach, seafront seafood and better value than Hua Hin.
Khao Lak (Phang Nga)
Long, quiet beaches with gentle high-season surf and many resorts with pools and kids’ activities — good for a longer stay.
Ao Nang (Krabi)
Krabi’s accommodation hub — walk to the beach and restaurants and take half-day 4-Islands tours, good for families who want island trips.
Koh Samui (Maenam/Choeng Mon)
Choose a calm beach like Maenam or Choeng Mon — shallow, still water for young children, with family resorts and an island airport.
Koh Samet (Rayong)
The closest island beach to Bangkok, with white sand and clear water, a short ferry from Ban Phe — great for a family weekend escape.
