Captain Ernesto Esguerra Cubides Air Base, known by IATA code TQS, serves the remote military and civilian hub of Tres Esquinas in the Caquetá department of southern Colombia. The facility functions primarily as a Colombian Air Force installation with limited civilian access, playing a strategic role in operations across the Amazon basin. Its remote jungle setting makes it one of the more isolated airstrips in the country, serving local communities with few alternative transport links.
- Military/Civilian Terminal — A single basic facility handling both military operations and limited civilian passenger movements in a remote jungle environment.
- Local taxi or mototaxi services in Tres Esquinas
- River boat transport along the Caquetá River
- Private vehicle hire arranged through local contacts

Food options at the airbase itself are extremely limited and primarily serve military personnel. Visitors should expect to find basic local Colombian cuisine — rice, beans, plantain, and freshwater fish — at small community eateries in the Tres Esquinas area. Bringing your own supplies is strongly recommended for extended stays in this remote region.
- Confirm all flight schedules well in advance as services are infrequent and subject to military operational priorities.
- Carry sufficient cash as ATM and banking facilities are essentially nonexistent in Tres Esquinas.
- Pack insect repellent and appropriate jungle gear given the dense Amazon environment and high humidity year-round.
- Check entry requirements and security clearances carefully, as this is an active military installation with restricted access.
