Ko Samet, a national park island just 12 kilometres offshore, is Rayong's crown jewel, its clear waters and white sand beaches contrast with the industrial landscape of the nearby mainland coast. The island's Hat Sai Kaew beach is the most developed, but walking even a short distance south reveals progressively quieter coves with snorkelling coral and the kind of uncrowded beach experience that has become increasingly rare in the Gulf of Thailand. On the mainland, Saeng Chan Beach with its distinctive crescent shoreline and gentle waves is a local favourite, while the Ban Pae Village Market near the Ko Samet ferry pier offers fresh seafood, dried squid, and the shrimp paste central to Thai cooking. Strolling through Ko Kloi Floating Market gives visitors a vivid taste of regional specialities and local life. Novotel Rayong Rim Pae Resort sits directly on Rim Pae Beach with panoramic ocean views, two outdoor pools, a kids' pool, an Aquas Spa, a fitness room, water sports, and a Kids Club — a fully equipped beachfront resort just steps from the gently lapping Gulf of Thailand. Novotel Rayong Star Convention Centre is well positioned for both the city's parks and the Central Plaza Rayong shopping centre, just five minutes away. Mercure Rayong Lomtalay Villas & Resort brings beachfront villa living to the Rayong coast with its rooftop Koh 17 bar offering panoramic sea views and creative local cuisine.
