Access to Aniak is limited to air and water. The state-owned airport has an asphalt runway that is lighted, and is equipped for instrument approaches. Regular flights are provided by several carriers, including charter operators. Float planes can also land on Aniak Slough. Fuel and supplies are brought in by barge during the summer; other goods are delivered by air year-round. There is no road connection to other villages, although trails and the frozen Kuskokwim River are used by snow machines during winter. When the river is frozen, it is used as an ice road to access Chuathbaluk, Crooked Creek and Bethel. A winter trail is marked to Kalskag (15 mi).
