Thailand is one of the top beach destinations in the world – with over 800+ beaches along its 3,219 kilometers (2,000 miles) of tropical coastline. The country's varied shoreline features everything from bustling resort areas to serene, hidden coves, making it a great place for both adventure seekers and families. Phuket, Koh Samui, and Krabi are among the top beach destinations in Thailand. Phuket is home to Patong Beach, known for its lively atmosphere, water sports, and vibrant nightlife. Koh Samui offers Chaweng Beach, a long stretch of white sand that is ideal for swimming and sunbathing. Krabi is famous for Railay Beach, accessible only by boat, and surrounded by towering limestone cliffs, offering a more secluded and picturesque setting.

Other notable beaches in Thailand include Maya Bay on Koh Phi Phi Leh, known for its stunning turquoise waters and as the filming location for the movie "The Beach," and Ao Nang Beach in Krabi, which is a great base for island-hopping and exploring nearby attractions.

The best time to visit Thailand for beach activities is from November to April, during the dry season, when the weather is warm and the seas are calm, perfect for swimming, snorkeling, and enjoying the sun.
