Short answer
Bang Pa-In Palace, about 18 km south of Ayutthaya, charges foreigners 100 baht and is open daily, but sources disagree on the hours: 08:30 to 17:00 on a Thai tourism portal citing TAT, 08:00 to 16:00 on Wikivoyage. Dress modestly, with shoulders and knees covered and closed-heel shoes; Wikivoyage says a 100 baht wrap skirt is sold at the entrance. Allow 3 to 4 hours at an easy pace. It is not on our Ayutthaya day trip route, so ask us if you want to add it.
What Bang Pa-In Palace is, and why it looks the way it does
Bang Pa-In Royal Palace is the former summer palace of the Thai kings, on the bank of the Chao Phraya River in Bang Pa-In District. Wikipedia says King Prasat Thong built the first complex in 1632, that it fell into disuse and became overgrown in the late 18th and early 19th centuries, and that King Mongkut began restoring it in the mid-19th century. Most of today's buildings date from 1872 to 1889, under his son King Chulalongkorn.
That explains the mix. Wikivoyage describes Thai, European and Chinese styles in one garden and says it was last restored in 2001. Unlike the temple ruins in Ayutthaya, the palace is intact and Wikipedia notes that it remains largely open to visitors. The Thai portal Lovethailand places it about 18 km south of Ayutthaya's island; Wikivoyage puts the town of Bang Pa-In 60 km north of Bangkok.
Entry costs 100 baht for foreigners
Lovethailand, which says it takes its rates from the Tourism Authority of Thailand, lists 100 baht for foreigners, 30 baht for Thai adults and 20 baht for children. Wikivoyage also gives 100 baht. We could not open an official page from the Bureau of the Royal Household in October 2026, so treat the price as the figure two sources agree on and check it at the gate.
Wikivoyage adds two costs inside the grounds. A golf cart costs 400 baht for the first hour and 100 baht for each hour after that, which suits anyone who finds the heat hard. Wikivoyage also mentions simple cafes inside the grounds and food stalls outside the entrance, without current prices. Carry some cash for the cart and for drinks.
Opening hours: two sources, two answers
Lovethailand lists the palace as open daily from 08:30 to 17:00. Wikivoyage lists it daily from 08:00 to 16:00. Both agree on every day of the week, and they differ by up to an hour at each end, so we cannot give you one exact time. Neither is an official notice from the palace.
The practical rule is to arrive by early afternoon. A walk at an easy pace takes 3 to 4 hours, or half a day, according to Lovethailand, so a visit that starts at 15:00 can end with you outside the gate. Call the palace office before you go if your plans are tight; Lovethailand gives 0 3526 1044 and 0 3526 1548 as its numbers. Phone numbers and hours both change, so check them.
The dress code: shoulders, knees and shoes
Wikivoyage says proper dress is required, as at all royal sites. Lovethailand gives the detail: cover shoulders and knees, avoid tight or very thin clothes, and wear shoes that fasten at the heel. The Tourism Authority of Thailand's etiquette note of 2018 describes the same standard for temples: a shirt with sleeves for men, a top with sleeves and a skirt below the knee for women, and no sandals without a back strap.
If you arrive in shorts, Wikivoyage says a 100 baht wrap-around skirt is sold at the stall in front of the entrance. Wat Niwet Thamprawat, the church-like temple across the river, is an active temple, so the same rules apply there. The simplest answer is to dress for it in the morning: lightweight trousers and a T-shirt with sleeves work in the heat as well.
What to see in the grounds
The famous image is the Aisawan Thiphya-Art, a Thai pavilion in the middle of a pond; Wikivoyage calls it the archetype of the Thai sala and says it is the only Thai-style building in the palace. Other buildings Wikivoyage lists as open to visitors are the Warophat Phiman, a one-storey European-style residence with Chulalongkorn's throne hall, and the Wehart Chamrun, a Chinese-style palace built by the Chinese Chamber of Commerce in 1889.
There is also a small museum in the Exhibition Hall, a painted lookout tower, the Ho Withun Thasana, and a marble memorial. King Chulalongkorn built it for Queen Sunanda Kumariratana and her daughter, who drowned in 1880 when the royal barge capsized after a collision with a steamboat, according to Wikipedia. It is a quiet corner, so keep your voice down there.
Getting there from Ayutthaya and Bangkok
Bang Pa-In is the stop before Ayutthaya on the northern railway line. Wikivoyage says several trains a day stop there, that the ride to Ayutthaya takes only 15 minutes and that the journey from Bangkok's Hualamphong station takes 1.5 hours. The air-conditioned BNEX service from Krung Thep Aphiwat also serves Bang Pa-In, with a promotional fare capped at 50 baht until 31 October 2026, according to The Nation; check the fare and timetable at the station.
By road, Wikivoyage lists minibuses and songthaews between Ayutthaya's central bus station and Bang Pa-In, taking about 40 minutes, and a taxi from Bang Pa-In to Ayutthaya at a fixed 150 baht. Tuk-tuks run between the stations and the palace. Wikivoyage also notes that a basic cable car crosses the river to Wat Niwet Thamprawat, from a station behind the car park.
Does it fit on an Ayutthaya day trip?
On a single day from Bangkok, rarely. Our Ayutthaya day trip from Bangkok lasts about 9 hours, with about 1.5 hours of driving each way, and it visits four temples: Wat Yai Chai Mongkhon, Wat Mahathat, Wat Phra Si Sanphet and Wat Chaiwatthanaram. Bang Pa-In is not on that route, and at 3 to 4 hours for a relaxed visit it would replace most of the temples.
If the palace matters more to you than the ruins, or you are spending a night in Ayutthaya, plan it as its own half day by train or taxi. If you want to see both, tell us when you book and we will say honestly whether the day can be changed. Our guide to the best temples in Ayutthaya helps you choose between the two.
