Boquillas del Carmen lies adjacent to the Mexico–United States border and visitors on foot from the United States can enter the village via the Boquillas Port of Entry. Situated just next to Big Bend National Park, tourism is the principal industry in Boquillas. After the September 11 attacks, the United States closed the border and the economy of Boquillas was severely affected and the population fell by nearly 50%. In 2013, the border was re-opened and the economy and population subsequently rebounded.
