Less than an hour from central Chiang Mai, there is a place where traffic noise disappears, the breeze moves through mango groves, lemongrass drifts from the herb beds, and everything you are about to eat is still attached to its stem. The Terra Lanna organic farm in Lamphun Province was not born from a trend. This is land our family has farmed for over 20 years — long before the word "organic" entered everyday conversation.
20 Years of Growing Without Chemicals
The farm started as a small household plot. Grandparents grew vegetables for the family table, made their own compost, and never bought pesticides — there was no need. The soil was healthy, the water was clean, and natural predators kept insects in check. Over two decades that small patch expanded into several rai of cultivated land, the plant count grew from ten to more than fifty varieties, and the accumulated knowledge of organic methods became a complete working system.
Today the farm is open to anyone who wants to learn, get their hands dirty, and experience northern Thai organic agriculture firsthand. Whether you are a family wanting your children to see how vegetables grow from soil, a couple looking for something genuinely different, or a group of friends tired of cafe-hopping — book a farm tour and come see for yourself.
What You Will Do on the Farm
Harvest Fresh Vegetables
Every morning the farm guide walks you through the vegetable beds. You pick your own salad greens, holy basil, sweet basil, chillies, tomatoes, and whatever herbs are ready for harvest. You learn the correct way to pick without damaging the parent plant, and you discover things about each crop you never knew — what light, water, and soil conditions each one needs. Everything you gather becomes the ingredients for your meal a few hours later.
Learn Composting and Organic Methods
One of the farm highlights is the closed-loop composting system. Nothing leaves the farm as waste — every scrap returns to the soil as nutrients. You see the process from start to finish: sorting food scraps, fermenting in dedicated bins, producing bio-extract fertiliser, and applying it to the growing beds. This is practical knowledge you can take home and use in your own garden, balcony, or even a kitchen windowsill.
Farm-to-Table Cooking
After harvesting vegetables and herbs, you move to the outdoor kitchen to cook a northern Thai meal. The menu changes with the season and whatever the farm is producing, but typically includes an herb-rich som tam, a stir-fry of mixed farm vegetables, green curry with chicken from a neighbouring farm, and fresh herbal drinks. The flavour is noticeably different from restaurant food — produce picked less than an hour ago tastes sweeter, crisper, more alive.
If you love northern Thai food, do not miss Uncle Prakit's khao soi at Kad Kom market before or after your farm visit — the perfect combo.
Nature Walk and Orchard Stroll
Beyond the vegetable plots, the farm includes a tropical orchard growing longan, mango, jackfruit, banana, coconut, and pomelo depending on the season. Walk under the canopy, photograph the paddies next door, or rest at the pond-side sala listening to birdsong. The farm keeps free-range laying hens, has a section of hand-planted rice paddies, and grows a dedicated herb garden of lemongrass, galangal, kaffir lime leaves, turmeric, and dozens more staples of the Lanna kitchen.
What Grows Here — 50+ Varieties
The farm rotates crops year-round. The core catalogue of more than fifty varieties includes:
- Salad greens: Green oak, red oak, butterhead, romaine, Chinese cabbage
- Herbs: Holy basil, sweet basil, lemongrass, galangal, kaffir lime leaf, turmeric, spearmint, coriander
- Vegetables: Tomato, bird's-eye chilli, cucumber, long bean, morning glory, Chinese broccoli, choy sum
- Fruit: Mango, longan, jackfruit, banana, coconut, pomelo, papaya
- Grains & other: Sticky rice, brown rice, sugar cane, corn, peanuts
What is ready for harvest shifts with the seasons. November through February is peak season for salad greens and cool-weather crops. April through June is fruit season, when longan and mango reach their sweetest.
The Philosophy — Why Organic Matters
Organic farming in northern Thailand is not a fashion statement. It is the original way. Before the agrochemical industry arrived in the 1960s and 70s, northern Thai farmers rotated crops, used animal manure, saved their own seeds, and relied on biodiversity as their pest control. What we call "organic" today, the grandparents' generation simply called "farming."
This farm chose to return to that path. After 20 years free of chemicals, the soil is alive — rich with microorganisms, earthworms, and natural fertility that needs no synthetic help. The produce may not look as uniform as supermarket vegetables, but the flavour tells you everything.
The best vegetables are not the prettiest. They are the ones grown in the best soil and the cleanest water — a philosophy passed down three generations on this farm.
Why Agritourism Is Growing
Over the past five years, agritourism in northern Thailand has grown steadily. People are asking where their food comes from, how it is grown, and who grows it. Young families want their children to experience something beyond screens. Repeat visitors to Chiang Mai are looking for depth beyond temples and cafes. A farm tour answers all of these needs at once.
We are not a farm stay — there is no overnight accommodation on the farm itself. This is a day-trip experience that pairs beautifully with the rest of a Chiang Mai holiday. See all tour programs or pair it with a stay at Nampiangdin Boutique Hotel and head to the farm the next morning — it is a combination that works perfectly.

- Closed-toe shoes or trainers, not flip-flops
- Sun hat and sunscreen — parts of the farm are open field

- Curiosity — the guides are happy to answer every question
