What the tree actually is
Yang Na (ยางนา) is the Thai name for Dipterocarpus alatus, a tall hardwood that grows across mainland Southeast Asia. It is a forest tree, not a crop. That matters, because the Thai word yang is also used for rubber, and visitors regularly assume they are looking at an overgrown rubber tree in the middle of a plantation. They are not. This is a wild giant that happened to survive the clearing of the land around it, and locals treat it accordingly.
The tree is also known locally as Ton Yang Yai — literally the big yang tree — which is where our own name comes from.
About the "biggest tree in Thailand" claim
You will see the Yang Na Yai described online as the largest tree in Thailand, and occasionally as the tallest tree in the country. Neither claim holds up. Careful writers who have looked into it note that bigger specimens exist elsewhere, and that there are probably larger trees deeper in Koh Phangan's own jungle interior, where nobody has measured them.
What makes this tree exceptional is not a record. It is that a four-century-old forest giant is standing beside a public road, in a village, where anyone can walk up to it on the way to the beach. There is no trail, no ticket, no national park gate. That accessibility is the real reason it became the island's most photographed tree — and it is a better story than a contested superlative.
How to get there
The landmark to navigate by is Wat Pho, the temple in Ban Tai. The tree stands within a few minutes' walk of it, beside the road, and the trunk is visible before you reach it. The most reliable approach is to search for the tree in Google Maps before you set out and follow the pin — it has a listing and reviews, so it will come up.
- From Thong Sala pier: head south and east towards Ban Tai; the drive is short, and the tree is a natural stop on the way to Haad Rin.
- From our villa in Ban Tai: a few minutes by scooter, and a reasonable walk if you set off before the heat builds.
- Parking: roadside. Pull off cleanly and leave room for traffic — this is a working village road, not a car park.
Do not rely on published coordinates from travel blogs. At least two of the widely copied listings disagree with each other, and the road names get translated differently depending on who wrote the page. The pin, or simply "past Wat Pho", will get you there faster than any set of numbers.
What to expect when you arrive
The tree is right at the edge of the road, so the visit is short: you walk around the base, look up, and take photographs. The trunk is broad enough that a group cannot link hands around it. Around the foot of the tree you will find small shrines and ribbons or garlands tied to the bark — villagers consider the tree sacred, and offerings are left there.
Which brings us to the only rules that matter.
Treat it as a shrine, not a prop. Do not climb it, do not carve into it, do not move or take the offerings, and do not pose in a way that treats the shrines as decoration. Dress as you would for a temple. If someone is praying, wait. A minute of patience here is the difference between being a guest and being a nuisance — and the tree is the one place in Ban Tai where that distinction is entirely on you.
When to go
Morning, before the light goes flat and the road starts to heat up. Late afternoon is the other good window, and it pairs naturally with Wat Pho next door: the temple runs a small herbal sauna in the afternoons, which is a genuinely local thing to do and costs very little. Together they make an easy two-hour outing that most visitors miss because they are driving past it towards Haad Rin.
After heavy rain the tree is at its most striking — the bark darkens, the crown holds water, and the whole thing looks considerably older than it does in the midday glare.
Why our villa is named after it
Yang Yai House & Villa takes its name from the tree. We live in Ban Tai, the village the tree stands in, and it is the landmark we give people when they ask what there is to see nearby. If you stay with us, the tree is a few minutes away — close enough to visit in the cool of the early morning and be back at the pool before breakfast.
Staying nearby
Yang Yai House & Villa is a three-bedroom villa with its own plunge pool in Ban Tai, sleeping up to six guests. You book it directly with us, and the dates are checked by a person before anything is paid.
