The mainland coast and the Koh Samet ferry beaches - from long, quiet Mae Ramphueng and pine-shaded Suan Son to the Ban Phe ferry pier and Koh Samet's Hat Sai Kaew, Ao Wong Duan and Ao Phrao - who each one suits, swimming and seasons, the ferry crossing, and where to live to be close.
Rayong's coastline runs quieter and more local than Pattaya's, split between the mainland's long, casuarina-shaded sands and the ferry crossing to Koh Samet, one of Thailand's closest islands to Bangkok. Mae Ramphueng and Laem Mae Phim give residents a genuine local beach without the crowds, pine-shaded Suan Son pairs a shaded swim with an evening seafood market, and Ban Phe's piers are the standard gateway to Koh Samet's more classic island beaches. Below is every major beach, who it suits, how the water is, and where to live to be near it.
Rayong province's longest beach, running roughly 12 kilometres of golden sand west of Khao Laem Ya toward Ban Phe. Clusters of pine-like casuarina trees line the shore, giving shade for beach chairs and the makeshift seafood shops selling grilled squid and som tam. It is quiet and local rather than a resort strip, drawing Rayong residents and weekending Thai families more than foreign tourists.
Named for the protected pine (casuarina) forest that shades nearly five kilometres of tan sand just outside Ban Phe, Suan Son is a calm, family-friendly stretch popular for a shaded afternoon on the beach. Its evening seafood market, set up along the tree line as the sun goes down, is a genuine local draw and one of the easiest ways to eat well without crossing to Koh Samet.
A low-key beach town further east along the coast from Mae Ramphueng, favoured by Thai weekenders looking for an easier, less commercial alternative to Pattaya. The beach itself is modest rather than postcard-perfect, but the relaxed pace, simple seafood restaurants and lower prices make it a genuine local escape rather than a tourist production.
Ban Phe's own beach is secondary to its job as Rayong's ferry gateway - passenger boats to Koh Samet leave roughly every half hour, a crossing of about 20-45 minutes depending on the boat and pier used. The waterfront's lively seafood market makes it a worthwhile stop for lunch or dinner before or after the island, with freshness and prices that are hard to match closer to Bangkok.
Koh Samet's flagship beach and the island's widest, whitest stretch of sand, a short walk from the main pier and lined with resorts, restaurants and beach-bar nightlife. It is the busiest beach on the island and the default choice for a first visit or a straightforward day trip from the mainland, reached by ferry from Ban Phe.
A curving bay on the island's east coast with a more relaxed, resort-driven atmosphere than Hat Sai Kaew's crowds, while still offering a full range of restaurants and water-sport rentals. A popular pick for travellers who want Koh Samet's clear water without the busiest beach's foot traffic.
The island's only west-facing beach, prized for sunset views and a handful of quieter, more boutique resorts set apart from the busier east-coast bays. The smaller, calmer coves further south and west suit visitors prioritising peace and quiet over nightlife.
The cool, dry season brings Rayong's calmest seas and most reliable beach days, on the mainland and on Koh Samet alike - the standard window recommended for a beach visit to this stretch of the Eastern Seaboard. It is also the busiest period for domestic weekend traffic to Mae Ramphueng, Suan Son and the Ban Phe ferry queues.
Ban Phe is the departure point for Koh Samet, with several piers running passenger and speedboat services roughly every half hour; the crossing itself takes about 20-45 minutes depending on the boat and the pier used on each end. Confirm which Ban Phe pier matches your chosen Koh Samet beach before booking, since piers serve different parts of the island.
The Gulf-coast monsoon brings mostly short afternoon downpours rather than all-day rain, and many beach days on the Rayong mainland and Koh Samet still hold up fine outside the wettest weeks. Seas can turn choppier on exposed stretches during storms, so it is worth checking conditions before a Koh Samet ferry crossing in this window.
It depends what you want. Mae Ramphueng is the longest and quietest mainland beach, Suan Son suits shaded afternoons and its evening seafood market, and Ban Phe is mainly the ferry gateway rather than a beach destination in itself. For postcard sand and resorts, most visitors cross by ferry to Koh Samet's Hat Sai Kaew, with calmer Ao Wong Duan and Ao Phrao as quieter alternatives.
Yes. Mae Ramphueng is a long, gently sloping stretch of sand generally suited to swimming, and it is far less crowded than Rayong's tourist-facing alternatives. As with any open Gulf beach, check local conditions and flags during rough weather or the rainy season.
Passenger and speedboat ferries run from several piers in Ban Phe roughly every half hour, with a crossing time of about 20-45 minutes depending on the boat and which Koh Samet beach or pier you're headed to. Ban Phe is Rayong's main gateway to the island and the standard route from the mainland.
Yes, in two distinct ways: a quieter mainland coast at Mae Ramphueng, Suan Son and Laem Mae Phim for local seafood and far fewer crowds than Pattaya, plus easy ferry access from Ban Phe to Koh Samet's more classic island beaches. It suits residents and relocators who want beach time without a long drive, more than travellers chasing a single headline beach.
