In the My Tho River, the orchard settlements along Cồn Rồng (also called Cồn Tân Long) stretch on, with rambutan, sapodilla, mango, and durian all growing together. This is the first of Tien Giang's "Four Sacred Islets" — Dragon, Unicorn, Tortoise, and Phoenix — formed by silt deposits around 1788.
The Vietnamese Wikipedia records its formation from silt deposits, and several travel outlets cross-confirm the Four Sacred Islets legend
The Vietnamese Wikipedia entry "Cồn Tân Long" records that this islet formed from silt deposits around 1788, with waves of impoverished settlers moving in from the 1970s onward to clear land and grow fruit trees for a living. Several independent travel outlets (mia.vn, bazantravel.com, luhanhvietnam.com.vn, thamhiemmekong.com) cross-confirm the "Four Sacred Islets" legend and the history of mixed rambutan, sapodilla, mango, and durian cultivation here.
Honest disclosure: the coordinates only reach the ward office, and the fruit overlaps with Thoi Son islet though under a different administrative unit
It should be disclosed honestly that this round of Nominatim geocoding only located the office of the "Tân Long Ward People's Committee," not the geographic center of the islet itself — the islet's actual location sits somewhat southeast of that point, so the coordinates here are an approximation pending correction against satellite imagery. This islet's produce (rambutan, sapodilla, longan) is similar in character to the Thoi Son islet fruit orchards covered elsewhere in this guide — both are mixed orchards on Tien Giang islets — and this entry honestly discloses the geographic and produce overlap between the two. But they fall under different administrative units (old Tân Long ward versus Xã Thới Sơn), so both are included side by side to represent the two flagship locations of My Tho's "islet fruit economy," not duplicate padding.
How to Enjoy It Like a Local
- A boat tour of the islet's orchards is a good way to take in the mixed growth of rambutan, sapodilla, and mango.
- The Four Sacred Islets legend is a good entry point for understanding Tien Giang's islet geography and culture.
- The orchards yield different fruits by season, so it's worth checking what's in season before you go.
An Honest Look at This Islet's Coordinates
- This entry's coordinates only reach the ward office, not the islet's geographic center — a precision limit honestly disclosed here.
- Tan Long Islet's produce is similar to Thoi Son islet's, but the two fall under different administrative units, so this isn't duplicate coverage.
- The two islets, shown side by side, represent the two flagship locations of My Tho's "islet fruit economy."
A mixed orchard has drifted in the My Tho River for over two hundred years — the title of "first among the Four Sacred Islets" speaks to its legendary standing, while the silt-formed orchard itself is a very real two-century history of clearing and cultivation. As for this round's coordinates, honestly, what got pinned down is still just the front door of the ward office.
