1. Railay BeachKrabi — Thailand’s Most Dramatic Coastline
Railay isn’t one beach—it’s a limestone peninsula with four distinct beachesaccessible only by longtail boat. Towering 200-meter karst cliffs surround turquoise bayscreating one of Thailand’s most Instagram-worthy settings.
Railay West is the main sunset beach with soft sand and swimming-friendly water. Railay East has mangroves (not swimmable) but cheaper accommodation. Phra Nang Cave Beach wins for scenery—its white sand beach sits beneath vertical cliffswith a sacred cave shrine filled with wooden phalluses left by fishermen seeking good fortune.
Rock climbers flock here for over 700 bolted routes ranging from beginner 5.6 to advanced 5.14. Half-day climbing courses cost around 1,200 THB.
How to get there: From Ao Nanglongtail boats depart every 30 minutes (100 THB15 min). From Krabi Town pierit’s 150 THB (45 min). No roads connect to Railay—boat only.
Best time: November to March (dry seasoncalm seas). April-May gets scorching. Monsoon (June-October) brings rough water but dramatic storm-watching.
Where to stay: Railay West has pricier resorts (2,500-8,000 THB). Railay East offers budget bungalows from 800 THB.
2. Maya BayPhi Phi Islands — The Beach That Became Too Famous
Maya Bay achieved global fame after starring in the 2000 film “The Beach” with Leonardo DiCaprio. Its 250-meter crescent of white sandenclosed by 100-meter cliffsbecame so overrun with tourists (5,000 daily at peak) that Thai authorities closed it for four years to allow coral reef recovery.
It reopened in January 2022 with strict rules: no swimmingno beach landingmaximum 300 visitors per hour. You can now only view it from a boat or walk across from the backside trail. Despite restrictionsthe scenery still delivers—the water glows emerald greenand baby blacktip reef sharks patrol the shallows.
How to visit: Most arrive via day tour from Phuket (1,800-2,500 THB) or Koh Phi Phi (800-1,200 THB). Tours typically include 6-7 snorkel stops at Phi Phi LehBamboo Islandand Monkey Beach.
Our take: Worth seeing once for the scenerybut Koh Phi Phi has better swimming beaches like Long Beach and Loh Dalum Bay where you can actually get in the water.
3. Koh Lipe — The Maldives of Thailand
Koh Lipe sits just 50 kilometers from the Malaysian border in the Andaman Seasurrounded by the Tarutao Marine National Park. Its water clarity rivals the Maldives—visibility reaches 20-30 metersand the sand is so fine it squeaks when you walk.
The island has three main beaches. Sunrise Beach (east) is the longest at 1.5 kmwith calm shallow water perfect for kids and jaw-dropping sunrises over the Adang archipelago. Sunset Beach (west) is the quietesta 500-meter curve with just a handful of bungalows. Pattaya Beach (south) has the most development—restaurantsbarslongtail boats offering island-hopping tours.
The snorkeling here is exceptional. You can swim straight from the beach to hard and soft coral gardens teeming with clownfishparrotfishand occasionally sea turtles. The 8 Islands snorkel tour (900 THB) takes you to the best spots around Koh AdangKoh Rawiand Koh Hin Ngam (the “stone island” covered in smooth black pebbles).
Getting there: Speedboat from Pak Bara pier (Satun province) takes 90 minutes (650 THB one-way). Ferries run November-April only. From LangkawiMalaysiait’s a 1-hour ferry (1,000 THB).
When to go: Peak season is December-February. The island essentially shuts down May-October when monsoons make boat transfers dangerous.
4. Kata BeachPhuket — Best Family Beach
Kata Beach sits 17 km south of Patong on Phuket’s west coast. It’s split into Kata Yai (main beach) and Kata Noi (small beach)both protected by headlands that keep the water calm for swimming.
What makes it ideal for families: the northern end has a shallow lagoon-like area where toddlers can splash safely. Lifeguards patrol year-round. The beach curves gently for 1.5 kmgiving kids space to build sandcastles away from the main swimming zones.
The vibe is more relaxed than Patong’s neon chaos but still has restaurantsbeach clubsand surf schools. Kata Surf House offers 2-hour lessons for 1,500 THB—waves here are gentle enough for beginnersespecially in monsoon season (May-October) when swells pick up.
Viewpoint: Climb to Kata Viewpoint (free10-minute walk from Kata Noi) for the postcard shot of three bays: Kata NoiKata Yaiand Karon in one panorama.
Accommodation: Ranges from backpacker guesthouses (600 THB) to five-star resorts like Katathani (8,000+ THB). Book direct to avoid Agoda’s 20% markup.
5. Haad RinKoh Phangan — The Original Party Beach
Haad Rin hosts the legendary Full Moon Party—30,000 people dancing on the beach until sunrise once a month. But there’s more to this peninsula than raves.
Haad Rin Nok (Sunrise Beach) is where the Full Moon Party happens. The 600-meter beach transforms into an open-air club with fire showsglow paint body artistsand bucket drinks (120 THB for vodka-Red Bull in a bucket—dangerously easy to overdo).
Haad Rin Nai (Sunset Beach)just 200 meters away on the west sidestays chill. It’s a proper swimming beach with calmer water and cheaper bungalows that don’t blast EDM at 3 AM.
Full Moon Party safety tips: Never leave drinks unattended (spiking happens). Wear shoes—broken glass is everywhere. Avoid swimming while drunk—tourists drown every year. Keep cash/phone in a waterproof pouch. Book accommodation 3+ months ahead or you’ll sleep on the beach.
Alternative parties: Half Moon Festival (smallerjungle setting)Black Moon Party (Ban Tai Beach)and countless beach bar parties that don’t require moon phases.
Non-party Koh Phangan: The northern and western coasts (Bottle BeachHaad YuanHaad Salad) offer tranquil beachesyoga retreatsand zero spring break energy.
6. Koh Tao — Dive Training Capital of Southeast Asia
Koh Tao (“Turtle Island”) transformed from a remote prison island into the world’s cheapest place to get PADI certified. Over 50 dive schools compete heredriving Open Water certification prices down to 9,500-11,000 THB (versus 15,000+ elsewhere in Thailand).
The island has 25+ dive sites within 20 minutes by boat. Chumphon Pinnacle regularly features whale sharks (best odds: March-May and September-October). Sail RockThailand’s best dive sitehas a vertical chimney swim-through and schooling barracuda. The HTMS Sattakut wreck lies at 30 metersits deck covered in soft corals.
Beach scene: Sairee Beach (west coast1.8 km) is the longest and most developedwith beach bars showing fire poi shows nightly. Shark Bay (north) has blacktip reef sharks visible from the beach—snorkel out 50 meters and you’ll spot them hunting in the shallows. Tanote Bay (east) is the quietesta small cove with granite boulders and excellent shore snorkeling.
Getting there: Lomprayah catamaran from Chumphon (2 hours600 THB) or overnight boat from Bangkok’s Khao San Road (650 THBincludes bus+ferryarrives 6 AM).
Best months: February-April and August-October for calm seas. November-December can be choppy. January sees plankton blooms that reduce visibility to 5-10 meters.
7. White Sand Beach (Koh Chang) — Jungle Island Escape
Koh Chang (“Elephant Island”)Thailand’s second-largest islandsits near the Cambodian border in Trat Province. Unlike Phuket’s wall-to-wall development70% of Koh Chang remains protected rainforest.
White Sand Beach (Hat Sai Khao) runs 2.5 km along the northwest coast. The sand is coarser than Andaman beaches—more golden than white—but the water stays shallow for 30+ metersmaking it safe for kids. Longtail boats from the southern end offer snorkel trips to Koh Wai and Koh Mak (600 THB).
The island’s real draw is the jungle interior. Rent a scooter (250 THB/day) and chase waterfalls—Khlong Plu Falls has a 25-meter cascade with a natural pool for swimming. The island road hugs the coastwith viewpoints overlooking Lonely Beach and Bailan Bay.
Getting there: From Bangkoktake a bus to Trat (250 THB5 hours)then ferry to Koh Chang (80 THB30 min). Or fly Bangkok-Trat on Bangkok Airways (2,500 THB one-way).
Vibe: More families and Thai tourists than backpackers. Lonely Beach (south of White Sand) is where the party scene concentrates.
8. Lamai BeachKoh Samui — Chaweng’s Quieter Neighbor
Lamai Beach runs 4 km along Koh Samui’s southeast coast. It’s Samui’s second-most-developed beach after Chawengbut the vibe is distinctly more laid-back.
The beach has a natural reef offshore that creates calm swimming conditions even when the Gulf of Thailand gets choppy. The southern end (near Hin Ta Hin Yai rocks—”Grandpa and Grandma Rocks,” naturally shaped like genitals) has the clearest water. The central stretch concentrates hotelsrestaurantsand weekly Lamai Night Market.
Samui’s wellness scene centers around Lamai. Tamarind Springs offers Thai herbal steams and jungle spa treatments (massages from 1,200 THB). The Yoga Thailand Shala runs drop-in classes (400 THB) in an open-air sala.
Day trip: The Ang Thong Marine National Park boat tour (2,200 THB) departs from nearby piers. You’ll kayak through lagoonshike to the Emerald Lake viewpoint on Koh Mae Koand snorkel with eagle rays.
When to visit: January-August is dry. September-December brings monsoon rains (but fewer tourists and 40% cheaper accommodation).
Freedom Beach
Freedom Beach hides between Patong and Karonaccessible only by longtail boat (a 15-minute ride from Patong Bay). That barrier keeps crowds thin—you’ll share this 300-meter white sand cove with maybe 50 people instead of 5,000.
The water gradient is spectacular: pale turquoise shallows transition to deep sapphire blue within 20 meters. Granite boulders frame both ends. There’s one beach club (Freedom Beach Club) serving Thai food and cocktailsplus beach chairs for 200 THB (includes water/towel).
Snorkeling here is decent—the rocky northern point has reef fish and occasionally sea turtles. But the real appeal is simply having space. You can claim a stretch of sand and not hear anyone else’s Spotify playlist.
Boat access: Longtail boats from Patong Beach charge 800-1,000 THB for a return trip (they’ll pick you up at an agreed time). Alternativelyjoin a speedboat tour that includes Freedom BeachCoral Islandand Racha Islands (1,800 THB from tour operators on Bangla Road).
Hiking option: A steep jungle trail from Patong (start near Retreat Beach Resort) takes 45 minutes. Bring water and wear real shoes—it’s slippery.
Nai Harn Beach
Nai Harn sits at Phuket’s southern tipa horseshoe bay backed by hills and a small lake (Nai Harn Lakewhere locals jog and do tai chi at dawn). This beach stayed undeveloped for decades because a Buddhist monastery owns much of the land.
The water here glows turquoise thanks to the white sand bottom and minimal boat traffic. Swimming is excellent November-April when seas are calm. May-October brings monsoon swells—red flags go up frequentlyand rip currents form near the rocky headlands.
There are no beach chair rentals or jet ski tours here. The low-key development means picnic vibes—Thai families spread mats under casuarina trees. The Royal Phuket Yacht Club anchors the southern end (the only high-end resort on the bay).
Sunset viewpoint: Promthep Cape3 km southis Phuket’s most famous sunset spot. Arrive at 5:45 PM to claim space among the tour bus crowds. The clifftop overlooks Nai HarnYanui Beachand the Andaman Sea stretching to the horizon.
Food scene: Nai Harn Beach Restaurant (on the beach) serves pad thai and green curry at local prices (80-120 THB). For upscale sunset dininghead to The Lawn at The Pavilions Phuket (1 km inland).
11. Long Beach (Koh Phi Phi) — Best Budget Beach
Long Beach (Hat Yao) sits on Koh Phi Phi Don’s eastern coasta 20-minute walk from the main pier or a 5-minute longtail boat ride (100 THB). This 500-meter stretch of sand is where budget travelers camp out—bungalows start at 400 THB for fan rooms.
The beach faces eastso you get sunrise views over the limestone islands. Water stays shallow for swimmingand longtail boat tours to Maya BayMonkey Beachand snorkel spots depart from the beach (800-1,000 THB for a half-day).
There’s minimal nightlife here—a few beachfront reggae bars with fire showsbut nothing like Tonsai Village’s hostel chaos. Most people crash early because there’s a 6 AM speedboat to catch.
Getting there: Phi Phi Islands are ferry-accessible from Phuket (2.5 hours450 THB) or Krabi (2 hours400 THB). Ferries arrive at Tonsai Bay; from therehire a longtail to Long Beach or walk the steep concrete path (tough with luggage).
12. Ao Nang BeachKrabi — Hub for Island Hopping
Ao Nang isn’t Thailand’s prettiest beach—longtail boats crowd the shoreand the sand has a grayish tint. But it’s the best base for exploring Krabi’s spectacular offshore islands.
The beach runs 2 kmbacked by a strip of hotelstravel agentsand restaurants serving 60 THB pad thai. You’re here for conveniencenot solitude. Four Islands Tour (650 THB) is the classic day trip: Phra Nang Cave BeachChicken IslandTup Island (with its sandbar connecting to Mor Island at low tide)and Poda Island for snorkeling.
Railay Beach is 10 minutes away by longtail (100 THB). Hong Islands tour (950 THB) takes you to the lagoon made famous by Instagram—a hidden emerald-green pool surrounded by limestone walls.
Night scene: Ao Nang has sports barsIrish pubsand seafood restaurants where you pick fresh fish/lobster from tanks (grilled whole fish around 350 THB). The night market (near McDonald’s) sells cheap clothes and street food.
Where to stay: Budget guesthouses near Ao Nang Beach start at 300 THB. For nicer accommodationcheck Nopparat Thara Beach (3 km north)—quieter with actual swimming conditions.
13. Sunrise BeachKoh Lipe — Best for Sunrise (Obviously)
Sunrise Beach (Hat Chao Ley) is Koh Lipe’s longest beach at 1.5 km. The sand is so soft and fine it squeaks underfoot. Water stays shallow for 50+ meters—you can walk out to the floating platforms without swimming.
Wake up at 6 AM and you’ll have the beach to yourself as the sun rises over Koh Adang. By 7 AMlongtail boats start ferrying snorkelers to nearby sites. By 9 AMbeach massage ladies set up shop (250 THB/hour).
The reef just offshore has staghorn coral gardens and resident hawksbill turtles. Rent snorkel gear from any beachfront shop (150 THB/day) and swim out 100 meters—you’ll find the drop-off where the coral starts.
Walking Street: The main Walking Street runs parallel to Sunrise Beachpacked with seafood restaurantsbarsand tour operators. It gets surprisingly lively at night despite Lipe’s small size.
14. Karon BeachPhuket — Best for Long Walks
Karon stretches 3.5 km—Phuket’s third-longest beach after Mai Khao and Bang Tao. The sand here has a unique texture: high quartz content makes it squeak when you walksounding like Styrofoam rubbing together.
This beach attracts fewer crowds than neighboring Kata despite similar water quality. The northern half (near Hilton and Centara) has the best swimming. The southern end gets rockier and sees fewer swimmers.
There’s a paved beachfront road (closed to cars) perfect for sunset jogs or bike rides. Karon has more of a resort town feel than a party beach—familiesChinese tour groupsand Scandinavian retirees dominate.
Monsoon season surfing: May-October brings 1-2 meter waves that attract beginner surfers. Surf schools along the beach charge 1,500 THB for a 2-hour lesson including board rental.
15. Koh KradanTrang — Most Underrated Beach in Thailand
Koh Kradan sits in the Trang archipelago40 km south of Krabi and largely ignored by mass tourism. The island has just two resortsno carsno convenience stores—only 1 km of powdery white sand beach and some of Thailand’s healthiest coral reefs.
The water visibility rivals Koh Lipe (20-25 meters on calm days). You can snorkel straight from the beach to hard coral gardens with schools of snappersfusiliersand occasionally hawksbill turtles. The reef drop-off starts 30 meters from shore.
There’s no nightlifeno WiFi (minimal cell signal)no tours to book. You’re here to swimsnorkelread books under palm treesand disconnect.
Getting there: Speedboat from Hat Yao pier in Trang (October-April only350 THB45 minutes). Some tours from Koh Lanta include Kradan as a stop—consider doing the four-island tour (KradanMookCheukWaen) for 1,200 THB.
Accommodation: Kradan Beach Resort has beachfront bungalows from 1,800 THB. Retreat Lost Resort offers backpacker bungalows (800 THB). Both include breakfast. Book ahead—the island has maybe 40 rooms total.
