Transportation The road from Quito to Tena is 99% paved as of 2021. It includes a spectacular passage over Papallacta Pass, above 4,000 m elevation, as well as views of several waterfalls. On clear days the 3,990 m Sumaco volcano can be seen to the east. There is bus service to Tena via Baeza which takes about 4 hours, and private transport from Quito takes about 3 to 3.5 hours. Small yellow truck-taxis are abundant in the city and cost $1.25. Around the time of the discovery of oil in the province, Mayor Galo de la Torre Airport was constructed to serve Tena. It closed in 2011. A new airport, Jumandy Airport located to the east near Ahuano, was inaugurated in 2011. The only airline that served it, TAME, ended flights to Tena in January 2016 citing low passenger loads.
