Chulumani’s tourist office is in a kiosk on the main plaza, but it's rarely open. If you are thinking of exploring the region it is worth seeking out hotel owners such as English-speaking Javier Sarabia at the Country House.
There’s no ATM in Chulumani. Prodem (two blocks west of the plaza on Pando) changes US dollars and gives cash advances on credit cards (5% commission).
The Entel office on Plaza Libertad is one of several central phone offices. Internet connections are sporadic but try Rayito Internet.
