This is the last full weekend before Halloween, and the calendar reads that way: trunk-or-treats in Littleton, Wheat Ridge, Arvada, Denver, Loveland and Johnstown, two nights of Treatsylvania and four nights of Pumpkins on Parade in Fort Collins, Harvest Hoot at the Children’s Museum of Denver and haunted hayrides in Highlands Ranch. If you would rather skip the candy, there are free bird and owl walks in Fort Collins and Littleton, a free artist studio tour in Fort Collins and a video game orchestra at Red Rocks. Every item links to our listing, which has the address, the price and the official source. Check the listing before you leave, because times and ticket availability can change.
