My preferred ATMs are the two Banjercito at the front of the military base--on Hwy 200 just before the Melaque/Custacomate intersection. Banjercito is the Mexican federal bank for the armed forces. Current ATM charge 18 pesos.

Parking difficult. Usually access by parking exiting Melaque heading to La Manz (or do a uturn to park across Hwy).
