It may sound like some Halloween-themed event, but the festival in a small town in southeast Colorado is really a celebration (and one town’s attempt to capitalize on it) of the annual tarantula migration. And while I’m being picky here, while it’s often called the migration, it’s more of a “mate-gration” or “walkabout” as the spiders are there all year. The males just come out and are on the move during this fall window in hopes of finding a mate and therefore easier to spot.
The actual viewing, which you can do you on your own or through guided tours, occurs in the National Grasslands outside of town, but can also stay busy in town with a parade, downtown festival with food vendors, and even a movie screening of Arachnophobia.
For more info, visit the town’s official festival website and read this interview with a CSU entomologist for more specifics on what you’re actually observing.
