Each fall, male tarantulas emerge from their burrows across the vast Comanche National Grassland in a mating‑expedition that draws visitors to spot these skittering bachelors in action, typically around dusk from mid‑September through October
La Junta’s annual Tarantula Fest takes place each late September in downtown, offering a weekend of activities including a parade, live art, vendors, educational programs, and tarantula tours to celebrate the region’s unique tarantula migration.
