A former ICAFE region around La Unión canton, now folded into the Central Valley as housing replaces coffee. Listed at 1,300-1,700 m.
Tres Ríos, the head town of La Unión canton in Cartago, long counted as one of Costa Rica's eight growing regions. Wikipedia lists it at 1,300-1,700 m with an October to January harvest and very high, fine acidity. ICAFE has since dropped it as a separate region and merged it into the Central Valley, citing coffee land lost to urban growth.
Field notes
- i
Tres Ríos disappeared from ICAFE's coffee-region map because urbanization kept eating its coffee land.
