Wear a not-too-scary costume for Eagan’s Halloween Trail Walk at Viking Lakes on October 24. The outdoor celebration runs from 11 a.m. to 2 p.m. and features trick-or-treat stations, Halloween games and dancing to the Monster Mash. Children need a $6 admission ticket. Adults can attend free with a food donation for The Open Door. Advance registration is required, and admission tickets are available only through Discover Eagan. The event takes place outdoors and goes ahead in rain or shine, so families should plan for the weather while visiting the activity stations around the Viking Lakes setting.
