Joaquín Figuerola

Guide / Fly Fishing Host

Joaquín’s relationship with fishing began during his childhood summers in Uruguay, fishing for croakers and silversides. On every family road trip, he eagerly anticipated the moment of crossing the bridges over the Paraná de las Palmas and Paraná Guazú rivers, dreaming of one day catching the large Golden Dorado he saw featured in fishing magazines.

Born and raised in Buenos Aires, he found the Lower Paraná Delta and the Río de la Plata to be the ultimate playground for his passion, targeting aggressive native species like the Golden Dorado and Wolf Fish (Tararira). In 2018, he took a key step by building his own cabin in the Delta, seamlessly weaving his connection with nature into his daily life.

Since joining Buenos Aires Fly Fishing as a guide and host, Joaquín has been guiding anglers from around the world, sharing the unforgettable thrill of landing a Golden Dorado on a fly just outside Buenos Aires.
