Koh Samui Durian Guide

In 2013 someone I trusted told me that Koh Samui Durian was the most epic Island Durian Experience you could ask for – think white powder beaches, turquoise seas, coconut fronds, a fresh wind – all while savoring a creamy handful of tree-ripe Durian from mountains jutting above the little beach towns.

So I went.

I disembarked from the Sea Tran car ferry at Nathon Pier with only a school-sized backpack of my belongings, took a songthaew toward Lamai Beach where that someone told me I would find cheap accommodations, and then did not find any durian at all.

The problem was that it was April.

Yes, the more famous durian provinces of Chanthaburi, Rayong and Trat have a durian season in April. But Koh Samui is located around 400 kilometers south across the Gulf of Thailand, with a very different rain-pattern and seasonality.

By expecting all of Thailand to have the same durian season, I’d made the ultimate n00b mistake. No, I would find no durian on this mountainous island in April – I would have to come back.

When I left, I didn’t realize it would take me thirteen years to come back and figure out the Koh Samui Durian Situation.

So finally, here is the blog post I wish I’d had on that first bumbling trip to Thailand’s most popular island destination.

• How much Koh Samui Durian is there?
• Where to buy Koh Samui Durian?
• How old is Koh Samui Durian?
• When is the Koh Samui Duiran Season?
• Koh Samui Durian Farms open to visitors
• Koh Samui Durian Stalls

How Much Koh Samui Durian Is There, Really?

In 2023, Koh Samui welcomed 3.54 million tourists to its beaches – but how many of those tourists explored Koh Samui’s inland mountains or thought about the island’s farmland?

There are day packages offering explorations of the interior mountains, with stops at zip-line adventures, elephant camps and waterfalls hidden in the undulating mountain ridges. Suped-up Safari songthaews ferry tourists on day packages around the steep interior roads, where the hills climb steeply upwards from sea-level to over 600 meters (1,968 feet) in just a mile or two.

But do those day-trippers realize that as they careen around the forested turns they are passing mile after mile after mile of durian farms?

Over 22-square kilometers of durian farms, lining the roads, carpeting the ridges, and dominating all the beautiful island vistas?

Most visitors probably assume there’s little farmland left, the land given over to tourist attractions and resorts.

But according to the Samui Agricultural Extension Office in Nathon, durian farming is now the biggest agricultural crop on Koh Samui Island, having tripled in production since my last trip here in 2013 – and almost all of it is in the mountains.

As of writing, the island produces over 30,000 tons of durian per season and that number is projected to double again in the next 2-3 years.

However little of that 30,000 tons is sold on the Koh Samui island.

Almost all of it gets put in trucks and ferried over to the mainland, where it gets sorted in durian packing houses and either sold in Bangkok or China.

It’s even difficult to find durian farms that sell locally on the island or accept guests to come eat durian.

Almost every farm has a buyer at the mainland packing house who personally travels over the gulf by ferry collect the fruits at the farm. He is the one who is responsible for checking that the durians are ripe enough to cut, and he brings with him a team of durian cutters who climb through the trees and take everything that’s ready –

– leaving little left for the Koh Samui’s durian hungry tourists!

No wonder casual visitors may not notice how much durian the island produces!

Never fear, we have you covered. Scroll down to find a few durian farms that are open and willing to sell to you directly.

Buying Koh Samui Durian

So if the majority of the durian gets sent away, what gets left on the island?

The good stuff, my durian friend.

See, the export industry is very picky about the durians it accepts.

It only wants durians that are cut early, at about 80% ripeness, so they can ship long distances without smelling or over-ripening. It only wants durians that weigh less than 4kg but more than 2kg – not too small but not too big. It wants durians that have a nice full shape, nothing lopsided or half-pollinated.

And it only wants Monthong. Hard, crunchy, half-ripe Monthong that will ripen over the days it takes to travel to its intended buyer.

Those epic-quality squooshy tree-ripe Monthong?

They stay on Koh Samui Island 😋 All for you, dear durian lover.

The place to look for them is at durian stalls along the Ring Road. But the next problem is that there seem to be very few stable durian stalls that sell every day.

Most durians seemed to be sold as just a few pieces randomly – in front of someone’s nail salon, on a folding table in front of a travel agency, tucked among some imported grapes and watermelons at a fruit stand. Maybe the shop owner’s cousin had a tree-ripe that needed to be sold right away, or their bestie’s durian was rejected from the packing house for having a weird shape, so then those durians get plunked in front with a sign for anyone passing by to nab.

We saw the majority of these little impromptu durian pop-ups in Mae Nam, Nathon, and Na Mueang. We saw ZERO durian for sale in Lamai at any time of day – morning, noon or night, I guess tourists in Lamai don’t have appetite for durian???

In Chaweng, in the evenings we saw pick-up trucks parked on the side of the road selling durian – but again these seemed to shift location every few days.

Below, we’ve listed three durian stalls we saw selling durian every day of our 6-week trip to Koh Samui.

How did Durian Get to Koh Samui? A brief history.

When the whalers ran of whales to kill in the 1880s and 1890s, the world found itself in an energy crisis. Whale oil lit street lamps and illuminated homes, lubricated machinery and engines, and was used in everything from soaps to margarine to explosives.

So the 19th century turned to another source of oil – coconuts. Coconuts covered the island, from the beaches to even the very tips of the mountains.

Coconuts were easy to grow and easy to sell.

According to one old farmer who misses the days of coconut farming, you didn’t get a lot of money per harvested nut, but it was easy money. The coconut tree produced 6 times per year, and didn’t require spraying with pesticides or fertilizers – no pruning, no babying the trees.

They just put them in the ground and collected the harvest for years and years.

The hard work was that if you had a farm in the mountains, the coconuts had to be carried down.Her father, brothers and various paid workers would hike up into the farm, collect the dried-out nuts and shell them there in the mountain, then carry them down in baskets on poles over their shoulders.

Once down at the coast, they loaded the coconuts in a two-wheeled carts drawn by water buffaloes, something similar to the image above – and brought them to the coconut trader, who purchased the lot no questions asked. He (or she) then arranged a cargo ship to send the nuts to oil presses in Chumphon or Bangkok.

By 1916, Koh Samui was so famous for coconuts that the island was regularly in planter’s magazines and even in the mainstream newspapers. “The export of nuts and copra from Koh Samui has reached considerable proportions.”

Side note: this is an excellent National Geographic article on Koh Samui’s unique practice of Buffalo Fighting that grew out of using buffaloes in the coconut fields

Then around the year 2010, the coconut trees died.

There were two pests at fault: the Coconut Rhinoceros Beetle Oryctes rhinoceros and the Coconut Weevil Rhynchophorus ferrugineus.

As the trees die, they loose their leaves and only the stem is left, rising like an empty pole into the sky.

If you look around the island today, you’ll still see sad, decapitated coconut trees that have lost the battle with the beetle and the weevil.

The coconut plague struck around the same time that Thailand signed a trade agreement with China allowing the export of fresh durian directly to the mainland, rather than routing through Hong Kong.

Thanks to the work of Grandpa Nim, by 2010 there was already a few hundred rai of durian being grown in Na Mueang area and shipped to Bangkok.

Koh Samui’s durian fate was sealed – it would now become a durian haven.

And that’s why when you drive around the mountains today, you’ll notice that almost all the durian trees are somewhere between 5 and 15 years old. But there are older farms as well, thanks to Grandpa Nim.

When is Koh Samui Durian Season?

We organized our Koh Samui durian-hunting trip for the end of August and September. If what I’d learned over the last 13 years about durian on this side of Thailand’s peninsula was correct, this *should be* the peak season.

After all, we’d found amazing quality durian in Koh Phangan in late August and September – and it’s definitely the best time to visit Khiriwong in mainland Nakhon Si Thammarat and the 300-year-old tree in northern Phattalung as well.

When we arrived to Koh Samui there was tree-ripe durian Chanee, Durian Baan and tree-ripe Monthong – however – every durian farmer or seller we met made haste to let us know that the 2025 season was weird.

Lots of trees either didn’t flower/fruit at all, or lost their fruits early due to heavy rains at the wrong time. So the quantity available during our trip was much reduced compared to normal. Boo – I’d waited 13 years to come on a bad year!

We did see that most farms were heavily in flower and baby fruit, and that Koh Samui was expecting a second season at the end of December through to February 2026. Farmers told me that it is normal for Koh Samui to have 2 seasons per year due to the abundance of rain on the island, with one season producing more heavily than the other.

I don’t think we will make it back to Koh Samui in the next calendar year, but if you do, please do tell us about your experience in the comments below!

Koh Samui Durian Farms to Visit

Tar Nim Magic Waterfall Garden น้ำตกตานิ่ม

This unique garden is on the tourist maps, but not for durian. The majority of those suped-up Safari Songthaews stop by this garden, and it might be the only durian garden on this list you’ve already heard about.

Grandpa Nim (Ta Nim) was not just any retired durian farmer with a penchant for mythological statues. He was the first person on the island to grow grafted varieties like Monthong, Kradumthong, Ganyao or Chanee. In fact, he is the one who brought these varieties to Koh Samui and spread them around to other farmers, and then also found the market to sell them.

He single-handedly paved the way for the whole durian scene in Koh Samui.

Thanks to his great-granddaughter Ti, we were able to learn his whole story and the story of the Magic Garden and share it on this blog. Read the whole story about Grandpa Nim’s Durian Gardens.

If you would like to buy durian during your visit to the Magic Garden, Ti suggests you request your tour guide to contact the garden beforehand and book some durians. Just request something ripe!

Rai Chomtawan Koh Samui ไร่ชมตะวัน เกาะสมุย

Perched on amazing vantage point above Nathon Town, this durian farm is on the rough dirt road crossing through the interior from Nathon to Mae Nam beach. It’s a popular thoroughfare for hikers and dirt-bike riders, but beware of driving this road without 4-wheel-drive.

It’s paved *almost* all the way to their farm if you’re coming from the Nathon side, but it’s a bumpy ride from Mae Nam.

Son-in-law Maneet manages the farm. He was born on a durian and rubber farm in mainland Chumphon, and married into this Samui coconut-growing family.

When he entered the scene, the family was struggling with their hilltop coconut farm.

The coconut farm was over 100 years old, and they were fighting an infestation of coconut beetles and weevils

With Maneet’s knowledge of durian farming, the family decided with some sadness to transition the old coconut farm into a Monthong durian orchard. Except for one Ganyao tree, the old trees were top-worked to Monthong and the 35-rai farm with the sunset view over Nathon was fully replanted with Monthong durians.

The trees are now about 15 years old and producing well. Maneet has found a mainland buyer for most of their durian, but the family has decided to keep the farm open for visitors as well.

Rai Chomtawan Farm ไร่ชมตะวัน เกาะสมุย welcomes Durian Eaters, but if you want to find something soft and edible, make sure to make an appointment beforehand.

Uncle Jed’s Organic Durian Farm

Uncle Jed and Auntie Nuy grew up as rice farmers in Hua Thanon beach area. In the 1980’s they bought a piece of land in the mountains just above their farm and followed all the recommendations for commercial durian farming at the time. They bought all the advised chemicals, followed fertilizer schedules, and after 15 years found that their trees were sick, dying, and the soil was badly eroded.

It was the last straw, and the couple decided to convert the farm entirely to organic.

Sixteen years later, says Auntie Nuy, the durian trees are free from disease. The soil has healed.

They planted native trees throughout the farm to act as water buffers and control erosion and have intermixed the durian trees with crops that just tickle their interest – soursop, egg fruits, avocados, chilis of different kinds.

They even have a tree of Durio kutejensis (Daeng Indo)!

But make no mistake – this is a very large durian farm. At 70 rai, it’s a lot of work, and produces a lot of durian.

They have mostly Monthong, but have kept their Durian Baan trees as well as planting an assortment of varieties – Chanee, Puangmanee, Ganyao, Musang King, and some hard to find ones like Kob Mae Thao.

Rather than buying organic fertilizers, the couple now makes their own fertilizers from rice husks, discarded fish bones and crab shells from the local markets, and food leftovers. They have a small education center where they teach other farmers how to make fertilizers.

– and they still have the old rice farm – organic certified as well – maybe the last relic of Koh Samui’s days as a food-sustainable island.

Suan Sam Anong สวนสามอนงค์

This semi-organic, pesticide-free durian farm is open to tourists all year long, but not for durian – for horse back riding and general fruit farm visits. If you want durian, make sure to notify them a day or two before you come.

Goh Hung (โกฮัง) was born in Laem Sor, one of Koh Samui’s southern beaches, to a first-generation Chinese coconut buyer and trader. As his father’s business prospered, the family invested in coconut farms as well.

As a child he remembers eating durian from giant, 100-year-old trees, but said those trees were now gone – either dead or converted via top-working to Monthong.

Around 1975, Goh Hung purchased a 100 rai rubber farm in the mountains. The farm already had a few standing durian trees, which he kept, and then cut down all the rubber to plant more durians.

He pointed at a durian tree next to the main house, which is original from before he bought the farm. It was a Durian Baan when he arrived, but he converted it to Monthong.

By the late 1970’s were already Taiwanese durian buyers sniffing around the island, looking for durian to ship back to Taiwan or Japan – Thailand’s main durian markets at that time.

So by the time Goh Hung’s durian trees matured, he already had buyers lined up for the harvest. Today, a buyer from Chanthaburi comes all the way down to collect the durians, and most of the durians are pre-sold before the season.

However, they do keep a few durians for themselves and guests, so if you want to combine your farm visit with some delicious old-tree durians, make sure to let them know in advance of coming.

Koh Samui Durian Stalls

Tua’s Durian Stall (Lipa Noi)

This durian stall was there, piled high with durian, every single day of our 6-week trip to Koh Samui. Other durian shops in Nathon came and went, but this pile of pomelos and durians was stable.

The owner’s name is Tua, and the table of durians sits in front of her stir-fried noodle shop on the Ring Road just south of Nathon Town. She told us that she gets the durians from friends up on the hill nearby called Khao Naw(เขานาว).

If there is no durian season in Koh Samui, she says she won’t have any. So this is a good place to go for local fruits.

We found a very good, fresh tree-ripe Chanee here amid a pile of yellowing Monthong.

Use the map below to find her stall.

เพ็ญทา Penta’s Durian Stall (Mae Nam)

Another durian stall that we saw every day of our trip to Koh Samui, rain or shine, was Penta’s shop along the Ring Road in Mae Nam.

Here we found Durian Baan that tasted like almond essence and cream, so good.

Penta said she sourced her durian from farmers up the hill in Mae Nam area, but wouldn’t give us any specifics. She also had bananas and backyard jackfruits for sale. She said she does not sell durian from off the island, so if you see her stall loaded with durians, it must be coming from Koh Samui.

Use the map below to find her stall.

Weiwei’s All-Year Durian Stall (Chawaeng)

This popular stall is near the Top’s Central Mall in Chaweng on a busy street. The owner, Weiwei, says she’s been selling fruit here for about 7 years already. She was busy flitting around the shop packing orders for Grab Drivers, and seemed to be making a hustling business.

When we visited, she was selling Koh Samui Durians – it being the local season. But when there are seasons in other parts of Thailand, like Chanthaburi or Kanchanaburi, she will buy durian from those locations as well and have them shipped to her store. Since different parts of Thailand have durian anywhere from February to October, she has durian available almost all year round.

If you’re visiting Koh Samui in the off-season, for example in April like one very naive durian lover, then this is your best bet to get some D.

Use the map below to find her stall.
