*There are numerous operators:
Backpacker tours - run by a German-Venezuelan family
# New Frontiers Adventures - operates mostly travel agencies and tour operators, but also through internet, not cheap
# Mystic tours - Apparently the oldest one. Good and cheap
# Marcos - great cook, slightly more expensive
Francisco - good and cheap too.
*There are a lot of Europeans on the trail. I did not see any Americans on the trip. There were some Venezuelans and mostly Germans, French and English tourists with ALL companies. In my humble opinion, German tourists are the worst degraders of the trail each carrying one porter or more per person.
