Bangkok isn't a beach city, but the Gulf coast and its islands are surprisingly close — close enough for a day at the sea or an easy weekend escape. The nearest sands at Bang Saen buzz with Thai families, Koh Larn and Koh Samet deliver genuinely turquoise island water, and the royal resort towns of Hua Hin and Cha-Am add markets and gentle charm. These 6 escapes, plus the car-free river island of Koh Kret, cover every mood, with travel times, ferry fares and tips.

Beaches near Bangkok in detail
1.Bang Saen Beach
Bang Saen, in Chonburi province about ninety minutes southeast of Bangkok, is the capital's nearest real beach and a firm favourite for a quick seaside fix, especially with Thai families and students rather than international tourists. It's not a tropical postcard — the long curving bay has golden-brown sand and gentle, sometimes murky Gulf water — but its appeal lies in the cheerful, authentic Thai seaside atmosphere. Rows of deckchairs and colourful parasols line the sand, and the great local ritual is to settle in for the day while vendors bring you fresh seafood, grilled squid, som tam, fruit and cold drinks right to your spot, and inner tubes are rented for a bob in the shallows. Weekends are lively and busy with day-trippers, while midweek is far calmer. A breezy seafront promenade is good for a stroll or cycle, and the nearby hilltop temple and viewpoint add interest. Because it's so close and easily reached by car, bus or minivan, it works well as an easy, cheap escape from the city heat and traffic for anyone who can't get to the famous southern islands. Come for the food, the sea breeze and a slice of everyday Thai beach life.
Hours
Always open
Price
Free; deckchair + parasol ~฿50–100
Getting there
About 1.5h southeast by car, bus or minivan to Chonburi's Bang Saen
Insider tip: The locals' seaside escape — rent a deckchair and parasol, order fresh seafood to your spot, and come midweek for calm.
2.Koh Larn (Coral Island)
Koh Larn, meaning Coral Island, is the easiest genuine tropical-island day out from Bangkok — a small island a short boat ride off Pattaya that delivers the clear turquoise water and powdery white sand the mainland resort beaches can't match. A cheap public ferry or a quicker speedboat from Pattaya's Bali Hai pier drops you at the island, where a scatter of beaches ring the coast. The main Tawaen Beach is the busiest and most developed, lined with sunbeds, restaurants and every kind of watersport, from jet skis and banana boats to parasailing and snorkelling trips over the reefs. For a calmer, prettier scene, rent a scooter or hop on a songthaew across to the quieter bays such as Tien, Nual or Samae, where the sand is finer and the crowds thinner. There are simple guesthouses if you want to overnight, but most visitors come for the day. Bring cash, sun protection and reef-friendly sunscreen, and note the last boats back. Combined with the journey to Pattaya, it makes a long but very doable day trip, and it's the go-to answer when Bangkok visitors crave a proper island-and-snorkel day without flying south.
Hours
Day boats from Pattaya pier; last returns late afternoon
Price
Ferry ~฿30 each way; speedboats & watersports extra
Getting there
~2h to Pattaya, then a 45-min ferry (or fast speedboat) from Bali Hai pier
Insider tip: Hire a scooter or songthaew to reach the quieter far-side beaches like Tien or Nual, away from the busy main strip.
3.Hua Hin
Hua Hin, on the Gulf coast around three hours southwest of Bangkok, is Thailand's original beach resort and a longtime royal retreat, giving it a more genteel, family-friendly character than raucous Pattaya. Its long, gently shelving sandy beach stretches for kilometres, backed by everything from grand old colonial-style hotels and modern resorts to seafood restaurants and spas, making it a relaxed spot to swim, ride horses along the sand or simply unwind. The town itself is enjoyable, centred on a charming historic railway station and a lively fishing pier area, and it's renowned for its markets: the bustling Chatchai night market for street food and souvenirs, and the artsy, atmospheric Cicada and Tamarind markets at weekends for crafts, live music and food. Golfers are well served by several quality courses, and nearby draws include the Phraya Nakhon cave with its royal pavilion, vineyards and national parks. While a touch far for a comfortable single day trip, it makes an ideal weekend or overnight escape, and the scenic train journey down is part of the pleasure. For a calmer, classier beach break with great food and gentle charm, Hua Hin is a Bangkok favourite.
Hours
Always open
Price
Beach free; sun-lounger hire modest
Getting there
About 3h southwest by train, bus or car; the scenic train is a highlight
Insider tip: Take the classic train to arrive at the pretty royal-era station, and eat your way through the Chatchai and Cicada night markets.
4.Cha-Am
Cha-Am, in Phetchaburi province a little north of Hua Hin and around three hours from Bangkok, is a low-key, distinctly Thai-flavoured beach town that makes an easygoing, wallet-friendly seaside break. Its long, straight beach is lined with the casuarina-shaded deckchairs and parasols that define the domestic Thai beach experience, and the local way to enjoy it is to hunker down for the day while vendors ferry over plates of grilled prawns, mussels, squid and som tam along with cold beers and coconuts. It's quieter and less polished than Hua Hin, drawing weekending Thai families and couples more than international tourists, which is exactly its charm for those wanting an unpretentious, affordable day or overnight by the sea. Beyond the beach there's little in the way of big attractions, though the historic hilltop palace of Phra Nakhon Khiri (Khao Wang) and Hua Hin's markets are close by. Seafood restaurants and simple resorts line the front. Because it neighbours Hua Hin, the two are often combined on a southern coastal trip. For cheap seafood, sun-loungers and a relaxed, authentic Thai beach vibe without the crowds, Cha-Am is a pleasant, unhurried pick.
Hours
Always open
Price
Free; deckchairs and seafood inexpensive
Getting there
About 3h southwest by bus, minivan or car, just before Hua Hin
Insider tip: Even mellower than neighbouring Hua Hin — grab a deckchair, order seafood and drinks to the sand, and watch the world go by.
5.Koh Samet
Koh Samet, off the coast of Rayong province southeast of Bangkok, is the closest genuinely gorgeous island beach escape from the capital, and a deserved weekend favourite. Part of a national marine park, this compact island is fringed with a string of beautiful bays of squeaky powder-white sand and clear, warm turquoise water, from the busier, facility-packed Sai Kaew and Ao Phai in the north to progressively quieter, prettier coves as you head south. Because it lies in the drier eastern Gulf, it enjoys sunnier weather than much of the country even in the rainy season, and its small size makes it easy to explore on foot or by songthaew. Days are for swimming, snorkelling and lounging with a book; evenings bring beachfront seafood barbecues, cocktails and fire-juggling shows once the day-trippers have gone. There's a range of accommodation from simple bungalows to smart resorts, and while a day trip is possible, staying at least one night is far more rewarding. Getting there means a roughly three-hour trip to Ban Phe pier followed by a short ferry, plus a national-park entry fee on arrival. For real island beauty close to Bangkok, Koh Samet is the top pick.
Hours
Ferries daytime; national park entry fee on arrival
Price
Ferry ~฿70–100 each way; park fee ~฿200; speedboats more
Getting there
About 3h southeast to Ban Phe pier, then a 30–40 min ferry to the island
Insider tip: The closest genuinely beautiful island beach — stay a night to enjoy the calm mornings and fire shows after the day boats leave.
6.Koh Kret
Koh Kret is a small, car-free island in the Chao Phraya just north of Bangkok in Nonthaburi, and one of the most charming, offbeat half-day escapes from the city. Formed by a man-made canal shortcut two centuries ago, it's home to a community of the Mon people, an ethnic group long celebrated for their distinctive terracotta pottery, which is still made and sold here alongside a small pottery museum. A flat, easy walking-and-cycling path loops the island past traditional wooden stilt houses, temples, small workshops and gardens, with barely a car in sight — just bicycles and the occasional scooter. The island truly comes alive at weekends, when a walking-street market unfurls with dozens of food stalls selling Mon and Thai sweets, snacks and dishes, along with crafts and the famous pottery, making it a favourite outing for Bangkokians in the know. On weekdays it's much sleepier, with many stalls closed. Reaching it is part of the appeal: head to Pak Kret, then cross on a tiny ฿5 ferry. Bring cash, sun protection and an appetite. For a relaxed, authentic, crowd-free taste of riverine Thai life close to the city, Koh Kret is a delight.
Hours
Liveliest at weekends; ferry crosses daily
Price
Cross-river ferry a few baht; free to explore
Getting there
~1h north to Pak Kret (Grab/bus), then a short ฿5 ferry to the island
Insider tip: This car-free river island is a weekend-only affair for the pottery workshops and food stalls — go Saturday or Sunday.
