WILLCOX, Ariz. (AP) — The National Park Service says it will boost camping fees at the Chiricahua National Monument from $12 a day to $20 per day starting Jan. 1. The changes in fees at the Bonita Canyon campground inside the Chiricahua National Monument are the first since 2002. Park superintendent Allen Etheridge says in a statement Tuesday that the increase was needed to fund maintenance and improvements at the park. The Park Service conducted a nationwide review of entrance and user fees this year.
