In the dim low light of a cardamom plantation in the hills above Thekkady, the air is heavy with a smell that does not exist anywhere else. It is the smell of the plant in flower, sweet, resinous, faintly citrus, faintly camphor. Walk a hundred metres into the plantation and the smell changes again. Older pods, ripening; the wet earth under them; the bark of the silver oaks that shade the cardamom plants from the direct sun. This is the small zone of the Western Ghats where the world’s finest cardamom has grown for a very long time, and where the small green pods that flavour everything from masala chai to Scandinavian buns to Arabian coffee begin their journey.
The Cardamom Hills are a specific stretch of the Western Ghats in the Idukki district of Kerala, ranging from around 600 metres to 1,500 metres in elevation. They are also officially called the Cardamom Hill Reserve, a name from the 19th century that the maps still use. The forests of Periyar Tiger Reserve sit at their heart. The story of how this small region came to grow most of the world’s high-grade cardamom is bound up with the story of the spice trade, the history of the kingdoms of southern India, and a quiet ecological accident that protected the trees while clearing other parts of the same mountain range.
This is a long-form post for travellers who want the full story before they visit. If you are planning to spend time in Thekkady or anywhere in the spice country of Kerala, this is the context that makes the place make sense.
Cardamom in the ancient world
The South West Coast of India was trading with the rest of the world long before most European countries existed. The Malabar Coast, the long stretch of Kerala from Mangalore down to Trivandrum, was the supplier of the world’s finest spices to Egyptian, Greek, Roman, Arab, Chinese and later European traders. The trade was old enough that the Romans complained about the gold drain to India. Pliny the Elder, writing in the first century, estimated that Rome was sending a hundred million sesterces a year to the East to pay for spices, gemstones and silks.
The most important Malabar port for much of this period was Muziris, the great trading harbour of the Chera kingdom, on the Kerala coast somewhere near the modern town of Kodungallur. Muziris exported pepper above all else – Vasco da Gama, arriving in Calicut in 1498, would later call it black gold, and so it had been for fifteen centuries before him. But Muziris also moved gems, ivory, timber, sandalwood, silk, pearls and a range of spices including cinnamon, ginger, turmeric and, in small quantities, cardamom.
A point worth getting straight, because the popular story often gets it wrong. Cardamom in this ancient period was not cultivated. It was a wild forest plant that grew on the lower slopes of the Western Ghats, and what reached Muziris was harvested by the indigenous tribal communities who lived in those forests. They collected the green pods, sun-dried them, and traded them through a chain of intermediaries, first to the villagers below the forest line for cloth and salt, then onward through bullock-cart caravans that followed the old elephant tracks down to the coast. By the time the cardamom reached the merchants in Muziris, it had passed through several hands, and it was rare and expensive enough that it travelled with pepper and gemstones rather than as a bulk crop.
It also did not travel well. Cardamom is a difficult spice to preserve. The volatile oils that give it its smell and flavour begin to escape almost as soon as the pod is dried, and without modern packaging or temperature control, the cardamom that reached Cairo or Rome was a shadow of the cardamom that left the Malabar hills. It was traded, valued and used – Egyptian medicine, Roman mouth fresheners, Greek perfumes, but it was never the volume crop that pepper was, and the quality fell off long before the buyer received it. The fame of Indian cardamom in the ancient world was real, but it was the fame of a rare and somewhat erratic luxury rather than of a reliable commodity.
This is the situation that lasted for the better part of two thousand years. Cardamom was a wild harvest from a remote mountain forest, traded in small quantities through a long logistics chain, valued where it arrived but not abundant. It would take an Indian princely state, in the 19th century, to change all of this.
The Travancore kingdom and the Cardamom Hill Reserve
By the 18th century, the political landscape of southern Kerala had shifted. The old Chera kingdom was long gone, and the southern half of present-day Kerala was now ruled by the kingdom of Travancore from its capital at Padmanabhapuram, and later Trivandrum. Travancore was an unusual Indian princely state, well-administered, financially careful, willing to invest in infrastructure, and with a strong commercial sense about its agricultural exports.
The Travancore administration recognised, in a way that earlier rulers had not, that the wild cardamom of the high ranges was a potentially enormous source of revenue if the supply could be made reliable. Wild harvest was unpredictable; cultivation could be taxed and managed. In the 19th century, the kingdom formally allocated a stretch of the Western Ghats, around 9,000 hectares of forested mountain land in the high ranges around Periyar, and designated it the Cardamom Hill Reserve. The land was leased to settlers and planters who agreed to cultivate cardamom on it, the produce was taxed, and the kingdom built roads, encouraged settlement, and developed infrastructure to maximise output. This is the period in which the Cardamom Hills became what the maps still call them.
Two things follow from this that travellers visiting today should understand.
The first is that the relatively dense, forested character of the Thekkady area is not a coincidence. Cardamom needs shade. It will not produce well in open sun, and it does not tolerate the heat that tea and coffee thrive in. The Travancore planters, in cultivating cardamom, kept the tall canopy trees standing, silver oak, jackfruit, mango, native rainforest species, because the cardamom plants below them depended on that shade. While other parts of the Western Ghats, including Munnar a hundred kilometres to the north, were being cleared wholesale for tea, the Cardamom Hills retained their forest. The crop, in a quiet ecological accident, protected the trees.
The second is that this is the period when cardamom became a reliable export commodity rather than a rare luxury. With cultivation came volume, with volume came quality control, and with quality control came a serious global market. Travancore exported its cardamom and pepper through the port of Alleppey, on the western coast a hundred and fifty kilometres from the hills. Alleppey was Travancore’s commercial port, a planned town with canals, warehouses, a pier and a working harbour, and from it Kerala’s spices sailed to the Middle East, Europe, and eventually the United States. The old godowns of Alleppey, many of them still standing, are a direct legacy of this trade. If you visit Alleppey today and walk the canal-side streets, the warehouses you pass were built to hold cardamom and pepper waiting for shipment.
By the late 19th century, the Cardamom Hills of Travancore were producing the bulk of the world’s high-grade cardamom, and they have not stopped since.
What cardamom actually is
For most travellers who arrive in Thekkady, the cardamom plant itself is a surprise. It is not a tree, and it is not a vine. It is a leafy ground-level plant, rather like a small ginger, growing in clusters between knee and chest height, with long ribbed leaves and small white-and-purple flowers that emerge from low stalks at the base of the plant. The pods, which are what you buy at the spice shop, develop on these low stalks, hidden under the leaves, often nearly at ground level. A worker harvesting cardamom is bent double or kneeling in the leaf litter, hand-picking pods one at a time.
The plant is a perennial. It takes about three years from planting to first significant harvest, and a well-managed plantation produces for fifteen to twenty years before the plants need replacing. Each plant flowers and fruits over a long season, typically August to February in the Idukki hills, which means harvest is not a single event but a series of pickings every fortnight or so through the season. The pods are picked while still green, because the volatile oils that give cardamom its character are at their highest concentration at the moment of greenness. Allow the pod to ripen and split on the plant, and the spice loses much of its value.
The picked green pods are taken immediately to a curing facility, where they are dried in carefully controlled conditions, traditionally over wood-smoke fires for a particular flavour profile, today increasingly in mechanical hot-air dryers for consistency and food-safety compliance. The drying takes around 24 to 36 hours, and at the end of it the pods have lost most of their water, retain their green colour, and have stabilised for transport and storage. Quality grading happens at the curing facility, by size, by colour intensity, by oil content, and the graded lots are then sent to auction.
The auction at Puttady
This part of the story has changed in the last decade in a way that is worth knowing about, because most older travel writing about the Cardamom Hills still describes a system that no longer exists.
Until recently, cardamom auctioning happened at several locations, Kumily, Vandiperiyar, and a few smaller centres, in the traditional Indian open-cry format. Auctioneers stood at the front of large halls, traders bid against each other vocally, and lots changed hands by the box. It was atmospheric and chaotic and a tourist favourite for those who could find their way in.
It is also gone. Cardamom auctioning for the entire region is now centralised at the Spices Park at Puttady, about an hour’s drive from Kumily. The Puttady auction is fully computerised, auctioneers and traders sit at terminals, bidding through software in a quiet hall, with the system processing thousands of lots per session. There is a small visitors’ gallery from which the activity can be observed, but the auction is not promoted as a tourist attraction. The administrators want to keep the trading floor functional, and an open visitor flow would interfere with that.
For travellers with a real interest in the spice trade, a visit can sometimes be arranged on advance notice. We have organised it for guests who came specifically for the spice story. It is not a busy spectacle in the way the old open-cry auctions were, it is more like watching a small commodity exchange, but it is a quietly fascinating window into the modern infrastructure that sits behind a 2,000-year-old commodity. Most visitors do not need to do this. For those who do, it is worth it.
What a traveller can see today
The way most travellers experience the Cardamom Hills is through a plantation walk, ideally on the property where they are staying.
Several of the better hotels in the Thekkady area sit on working spice plantations, and arrange guided walks for their guests. This is the most authentic way to see cardamom in cultivation, you walk between the rows of plants, see the flowers and the pods at the base, smell the plant in different stages, see the silver oaks and jack trees that shade them, and usually pick up a few related plants along the way: black pepper twined up the same shade trees, cinnamon, nutmeg, clove, vanilla, allspice, and a roster of medicinal plants that quietly underpin Kerala’s Ayurvedic tradition.
A practical note. Working commercial plantations that are not attached to a hotel generally do not host visitors. They are running businesses with limited spare staff, and they are not set up for tourist flow. The small show gardens that line the Kumily-Thekkady main road can be skipped, they are tidy and functional but commercial in feel, and most of the plants you will see at any half-decent hotel anyway. The plantation walk on hotel property, with a good guide, is what we recommend.
For travellers who want to go deeper than the plantation walk, the Puttady auction visit (by arrangement), a Thekkady spice market walk, and a longer conversation with a working planter can all be built into a custom programme. This is not a fixed tour we run, the cardamom country rewards a customised approach, because the right experience depends on what the traveller is interested in. A food-focused traveller wants to spend time in a kitchen with a planter’s family. A spice-trade-focused traveller wants the auction, the curing facility, and the warehouses at Alleppey. A botanically curious traveller wants the wild cardamom areas inside the forest reserve, with a naturalist. We are happy to design any of these, see the note at the end of the post.
Cardamom’s quiet companion – Malabar pepper
It is hard to talk about the Cardamom Hills without mentioning pepper, because the two crops grow together. Black pepper is a vine, and on a working cardamom plantation you will see it climbing the same shade trees that protect the cardamom plants below. The pepper from this region is among the most piperine-rich pepper grown anywhere, piperine being the alkaloid that gives black pepper its heat and its characteristic sharpness, and the spice trade has long geo-tagged it as Malabar Pepper. Pepper from the slightly higher slopes around Tellicherry, in northern Kerala, is sold separately as Tellicherry Pepper, generally considered the finest grade in the world.
The pepper trade, unlike cardamom, was already ancient and reliable when Muziris was operating. It did not need a Travancore-era cultivation push to make it commercially significant, it had been the headline crop of the Malabar Coast for two thousand years. But the modern productivity of pepper from this region, and its quality consistency, is a product of the same plantation infrastructure that the Travancore cardamom programme established. The two crops, grown together, sustained the spice economy of central Kerala through the 20th century and continue to sustain it today.
Why this matters for a Kerala visit
A traveller arriving in Thekkady for the first time often thinks of it as a wildlife destination. The Periyar Tiger Reserve is, after all, the headline attraction. But the wildlife sanctuary itself is partly a product of the Cardamom Hills’ long history as a managed crop landscape. The forests that the tigers, elephants and gaur live in are forests that were preserved precisely because cardamom needs shade. The dam at the centre of the lake was built in the 1890s, in the same Travancore-British period that created the Cardamom Hill Reserve. The roads that take you up from Kochi were built to move cardamom and pepper, not tourists.
Spending two or three days in this region, and engaging with both its forests and its plantations, gives you a richer experience than treating either side in isolation. The wildlife is real and worth seeing. The spice country is real and worth seeing. The fact that one made the other possible is what makes Thekkady a more interesting destination than the simpler version of either story would suggest.
Plan a cardamom-focused experience
We design custom programmes for travellers with a real interest in the spice country of Kerala. There is no single fixed cardamom tour, because the right experience depends on whether you are coming for the plant, the trade, the food, the history or the landscape. If any of those interest you, tell us what you are looking for and we will build the right programme, anchored in Thekkady, extending as far as you want, and as deep into the working spice country as your time allows.
For broader context, see our Thekkady destination guide for the full picture of the region, and our Munnar destination guide for the contrast, tea hills above, spice forests below, the same Western Ghats taking two very different agricultural histories.
