No buses go all the way around the loop. From Latacunga, they only travel as far as Chugchilán, either taking the southern road through Zumbahua and Quilotoa or the northern road via Saquisilí and Sigchos. Tigua is served by regular buses passing between Latacunga and Quevedo. If you’re more adventurous, catch a lechero (milk truck). If speed is your need, hire a taxi in Latacunga; rates start around $60.
