Comanche National Grassland is a National Grassland located in southeastern Colorado, United States. It is the sister grassland of Cimarron National Grassland and contains both prairie grasslands and canyons. It is separated into two sections, each operated by a local ranger district, one of which is in Springfield and the other of which is in La Junta.
We happened upon this place to see the annual tarantula migration that takes place in south east Colorado in the early Fall. We stopped in La Junta Colorado for the nite. Dusk is the time to see these critters. We were on highway 109 between La Junta and Kim Colorado.
