What there is to see in Thailand comes in three layers: the three great temples of Bangkok, the old capital of Ayutthaya to the north and the Andaman Sea to the south. Ayutthaya is about an hour from Bangkok, within day-trip range; Phuket is a domestic flight away. So rather than “what to see”, settle “how many nights in Bangkok, and whether you fly south” first and the itinerary is all but fixed.
This article lays out the classic nine spots split five in Bangkok, two in Ayutthaya and two in Phuket, with entry fees, timings and where to walk next. From any one of them you can go straight into the deeper guide.
Get the geography first — temples clustered along a river, and an island you have to fly to
Bangkok’s sights are clustered along the Chao Phraya. The three great temples connect on foot and by cross-river ferry alone, so half a day covers them together. The Muay Thai stadium and Chinatown, on the other hand, sit apart to the east and assume you move by rail (BTS/MRT) or a ride-hailing app.
Ayutthaya lies north of Bangkok, within day-trip range about an hour to an hour and a half by rail. Phuket is a domestic flight south, not something you connect over land. Finish with “Bangkok plus Ayutthaya”, or add a southern island and split the trip — that is the first fork.
Five in Bangkok — from the three great temples to a stadium at night
The Grand Palace and Wat Phra Kaew — the strictest dress code of them all
The sanctuary of the Thai royal house, where gilded stupas and riotously coloured ornament make the definitive “this is Thailand” space. The Grand Palace and Wat Phra Kaew (the Temple of the Emerald Buddha) share a single 500 B ticket. The dress code is the strictest anywhere here: shorts and sleeveless tops are refused. Cover-ups are sold at the gate, but bringing your own is safer. Starting here and walking south along the river is the standard move.
Wat Pho — a 46-metre gilded reclining Buddha
Within walking distance of the Grand Palace. The body of it is the 46-metre reclining Buddha that fills the hall, and it is also known as the home of traditional Thai massage. Entry 300 B, cash only. Coming straight out of the crowds at the Grand Palace, the change of scale lands harder.
Wat Arun (the Temple of Dawn) — 5 B across the river
A stupa clad in fragments of porcelain, standing on the far bank of the Chao Phraya. Entry 200 B, cash only, and the cross-river ferry is 5 B a head. This “cross the river, go from temple to temple” movement is itself the Bangkok experience, and the reason the three great temples work as a single half-day block. How to walk the city is in the Bangkok travel guide.
Rajadamnern Stadium — the oldest ring built for Muay Thai
It has been reborn as a modern promotion under the “RWS” brand, and under laser lighting and heavy sound the card runs as close to four hours of combat-sport festival from the first bout. From the traditional wai kru ritual it turns, and the tension of a fight where elbows and knees cross is something you only get in the room. At the box office, reckon on ringside from 2,000 B and third class at 1,000 B, and buying online in advance is the safer play (touts on the day charge more; as of July 2026). Traffic around the venue is heavy, so leave early.
Yaowarat (Chinatown) — the street itself is the entertainment
For eating your way through an evening, this is the place. Stalls fill the roadway and walking is itself the experience. Bangkok’s food belongs to stalls and canteens: pad thai, massaman curry, khao niao mamuang (mango sticky rice) — the signatures alone outnumber the meals you have. Entry at Wat Pho and Wat Arun, the ferry and the stalls are all cash only, so carrying plenty of small notes keeps you moving.
Two in Ayutthaya — a ruin field of brick chedi
The old capital where the Siamese kingdom held four centuries of glory. The ruins left by the Burmese invasion are preserved as they fell, as a World Heritage archaeological park. There are three ways to get there: rail (about 1 to 1.5 hours, from 15 B) / rot tu minibus (about an hour, 70 B) / a ride-hailing app or a tour (about 1 to 1.5 hours, from around 1,000 B one way). Entry to each major site is 80 B, and a six-site combined ticket is 300 B (as of July 2026).
Wat Mahathat — the Buddha head held in a bodhi tree
The symbol of an Ayutthaya visit. The Buddha head cradled in tree roots is a single image in which destruction and regrowth are visible at once. The sites are spread wide, so get around by tuk-tuk (negotiated, reckon on 50 B a ride) or rented bicycle (reckon on 50 B a day). Four or five sites in half a day is the realistic count.
Wat Ratchaburana — a chedi you can climb down inside
A well-preserved chedi standing right next door to Mahathat. Take these two as your anchors and the centre of the park is covered on foot alone. The logistics of the day trip are in the Ayutthaya day-trip guide. Note that April is the hottest month of the year and Songkran, the Thai New Year water festival, puts the town into a different mode, so if you are choosing for comfortable ruin-walking it is the month to avoid.
Two in Phuket — flying out to the Andaman Sea
Patong Beach — three kilometres of sand, and the town behind it
The beach on the west coast with the most food, shopping and nightlife. Behind about three kilometres of sand stand hotels, canteens and massage shops, and it remains the strongest base for a first trip to Phuket. For quiet, Karon and Kata to the south; for luxury resorts, the Bang Tao area in the north — the same island but each beach has a different character. In the rainy season, checking for the red flag, meaning no swimming, every morning is the etiquette.
The Phi Phi Islands — a day run out to a sea of limestone karst
About an hour from Phuket by speedboat (about two hours on a larger vessel). Vertical limestone walls with emerald inlets at their feet. In the rainy season, a larger boat rides steadier and is the standard defence against seasickness. Maya Bay, the setting of the film The Beach, is under environmental management: closed every year from 1 August to 30 September, and after reopening, swimming inside the bay is banned and numbers are capped (national park fee, 400 B for adults, on top) — whether it is in your itinerary depends on the season the tour runs, so check before booking (Phuket travel guide).
By length of stay — how far these nine get you
- 3 nights — Bangkok only: the three great temples on day one (they connect in half a day), markets and Chinatown on day two, Muay Thai in the evening. Temples are cooler and emptier in the morning (Bangkok travel guide)
- 3 nights plus a day trip — Bangkok and Ayutthaya: give one of the middle days to Ayutthaya. There is little shade among the ruins, so leaving early and coming back in the early afternoon is the physically correct shape (Ayutthaya day-trip guide)
- 6 to 7 nights — split the city and the island: three nights in Bangkok plus three in Phuket. Fly south and give one day to the Phi Phi Islands. One trip gets you both the density of the city and the openness of the sea
- 8 days — pair it with Vietnam: Bangkok and Ho Chi Minh City are about an hour and a half apart by air. It strings together two cities whose texture is completely different (Thailand & Vietnam itinerary)
Three things to settle before you go
- Entry formalities (TDAC) — every foreign national must register the digital arrival card in advance. Registration opens 72 hours before arrival, is free, and you show a QR code. The only official site is tdac.immigration.go.th; beware of imitation sites that charge a fee (as of July 2026)
- Timing — the best season is the dry months, November to February. For the southern islands, December to February gives the best sea and the best odds of clear skies, and prices jump over the new year. April is the hottest month of the year, plus Songkran. The rainy season brings room rates down but the sea gets unpredictable
- Clothing and cash — at temples, mind shoulders, knees and ankles, and carry something to throw over. Entry at Wat Pho and Wat Arun, the ferry and the stalls are cash only, so having plenty of small baht notes keeps you from stalling
Prices and rules change. Check entry fees and whether things are running on the official sites before you go. The shape of the country as a whole is set out in the Thailand travel guide.
