Mesook Farm (Agarwood Farmer Group)

Mesook Farm is a working agarwood plantation in Kachet subdistrict, just outside Rayong town, where a local farmer group runs guided walks through more than 200 rai of trees — some over 30 years old — and demonstrates the full process from cultivation to resin extraction. Entry to walk the grounds is free; food, drinks, and activities like kayaking cost extra. Open daily, 9 AM to 5 PM.

Agarwood only forms its valuable resin when a tree is wounded or infected — a defence response the tree mounts by producing a dense, fragrant compound around the injury. Farmers here walk visitors through that process step by step: how young saplings are planted and tended for years before any resin forms, how the infection is induced and monitored, and how the resin-heavy wood is eventually harvested and distilled into oil. The farm group has picked up a National Outstanding Farmer award for the work, and the plantation itself has become as much an educational stop as a working business — Rayong province lists it among its recommended agritourism sites.

Beyond the tree rows, the farm keeps the visit varied: a lake for kayaking, pens where you can feed giant catfish, wild boar, and goats, and a small buffalo herd. Mesook Cafe on site serves food and drinks, including a signature “Krisana coffee” made with agarwood extract, and the farm sells its own line of agarwood incense and fragrance products — a direct look at what the resin becomes once it leaves the tree. A handful of resident Samoyed dogs tend to greet arrivals at the entrance, which visitors reliably mention as an unexpected highlight for kids.

The rich, woody scent of the plantation is noticeable from the entrance path, strongest near the older trees where resin formation is furthest along. Mornings are the most active time for demonstrations and the most comfortable for walking, before the afternoon heat sets in.

Insider Tip: Ask staff to point out a tree with visible resin scarring rather than just walking the rows — seeing the actual infection marks makes the extraction explanation click in a way photos of finished incense don’t.

Watch out: The grounds are working farmland, not landscaped paths — wear closed shoes and bring insect repellent, especially near the lake.

Mesook Farm sits a short drive from central Rayong, an easy half-day stop if you’re based in town rather than out on Koh Samet.
