Yup'ik dancing is popular in the village. The high school has an Yup'ik Dance Team which often visits other villages for feasts and festivals. Often the village hosts a dance festival in April, and the large Camai-i festival in Bethel attracts many from Chefornak and the surrounding villages to display their dances and to see the dances of other regions.
Many of the villagers live a subsistence lifestyle, which means that they continue to carry out the traditional hunter-gatherer activities of their ancestors. One of the foods that they rely on is fish such as halibut, salmon, and herring, which are dried and eaten like jerky. Berries such as salmonberries (cloudberries), black berries (crowberries), and blueberries (bog bilberries) are also gathered and used to prepare akutaq. Other native foods that are gathered include mousefood, Labrador tea, and greens such as sourdock.
Beside houses, there are only a handful of buildings in the village:
- Chefarnrmute, Inc., the village corporation
- Avugiak's Store
- The post office
- The town hall/bingo hall
- The school (elementary and high school are in one building)
- Chaputnguak High School
- Amakigcik School (primary school, named after the Yup'ik elder who selected the village site)
- The Old School (formerly B.I.A. school)
- St. Catherine of Siena Catholic Church
- The power plant
Transportation into the village of Chefornak occurs primarily by small aircraft, although in the winter the village can be reached by snow machine as well. Goods and mail are brought into the village by plane, and during the summer months are brought up the Kinia River by barge. Chefornak's airport is in the process of being moved further from the village due to concerns with its proximity to the school. The new airstrip has been constructed, but the gravel must settle for several years before the airstrip is usable. Within the village, transportation options include four-wheel, bicycle, snow machine, and on foot.
