Giant tree

The giant tree at Ban Sanam, in Ban Rai district of Uthai Thani, is a single old-growth tree that locals say is close to 400 years old — its trunk wide enough that it takes roughly 80 people joining hands to encircle it. Villagers call it Ton Sieng or Ton Phueng (“Bee Tree”); “giant tree” is the tourist-facing English name. Entry is free.

The tree stands within a grove of areca palm, with roots spreading wide across the surface to help brace the trunk rather than digging straight down — a growth habit typical of very old trees on shallow soil. There’s no ticket booth or visitor centre, just a path in from the road and the tree itself; the appeal is entirely the scale of it, and standing at the base gives some sense of how much has passed since it was a sapling.

The canopy spreads wide enough that visitors can stand underneath it and still be within its shade on most sides. Thai travel write-ups often group the tree with the country’s “Unseen Thailand” sights — a label used for lesser-known attractions considered worth the detour rather than headline destinations. In practice that means a steady trickle of day-trippers and photographers rather than tour buses; it’s rarely crowded even on the weekend market days.

The tree originally belonged to the father-in-law of a local resident remembered as Heng, and was reportedly slated to be sold to timber traders for wood products. Heng asked to keep it instead, recognising its value, and the community has cared for it since — informal stewardship that’s likely why it survived in a district where old-growth trees were routinely logged for timber.

Insider Tip: Go on a Saturday or Sunday and combine the tree with the small market that sets up at the entrance, selling wickerwork, local clothing, food and dried herbs for brewing tea. Sao Hai Market, roughly a kilometre away, runs the same weekend-only schedule if you want a wider spread of stalls.

Morning is the best time to visit — cooler temperatures and better light for photos under the canopy. Bring mosquito repellent; the shaded, leafy setting holds onto humidity. It’s a short stop, so pair it with other Ban Rai sights such as Namtok Tat Dao or Pha Rom Yen Waterfall to fill out a day in the district.
