Bolivian Spanish word
el trufi
Meaning: shared taxi/van on a fixed route
How it is used in Bolivia
Trufi routes are learned by lore, not signage, everyone just knows where each one goes, and asking is completely normal.
The classic way to reach Samaipata from Santa Cruz. Usually no printed timetable, it 'sale cuando se llena', it leaves when it's full, so the departure time is something you confirm, not assume.
The everyday Bolivian way to travel between Santa Cruz and nearby towns: a car with a fixed route where you pay one seat. For Samaipata it is THE option locals name first.
