Hays ? Visitors to the Cheyenne Bottoms Wildlife Area in west-central Kansas are getting some extra guidance.

Biology graduate students at Fort Hays State University have started leading van tours of the wetlands. The university says the effort is being organized by the Kansas Wetlands Education Center of the school’s Sternberg Museum of Natural History.

The education center’s manager, Curtis Wolf, says people can drive through Cheyenne Bottoms any time they want for free. But visitors often say is they saw a lot of water and birds but didn’t really know what they were.

Wolf says the goal of the tours is to provide visitors a fuller experience.

The tours are given Tuesdays through Fridays by reservation. One is 30 minutes, and the other is 90 minutes.
