Parkhill Prairie

A  grassland park located in extreme northeast Collin County, Texas. The tax payers of Collin County provided the funding for this park in 1983 by passing the Open Space Bond Fund of Collin County. The park was contracted in 1986 and dedicated April 28, 1990.

The park features a  acre relic of the Blackland tall-grass prairie and provides magnificent views of the countryside, much like those viewed by the early Texas settlers more than 100 years ago. Covered pavilions with cook pits and restroom facilities are available. The park is open during daylight hours.

In the Spring, this park serves as an abundant wildflower locale, as well as a birding resource, with nesting pairs of meadowlark and dickcissel. Butterflies are common here, with sightings of numerous species possible. Wildflowers on the prairie include prairie parsley, wild petunia, Indian paintbrush, winecup, prairie clovers, meadow pinks, purple coneflower, Mexican hat, gayfeather, azure sage, goldenrods and asters.

Two small ponds at Parkhill Prairie feature sunfish fishing on a virtually year-round basis. The park is a little-used resource, located on the very gently rolling hills common to this region. The frequent mild winds common to this area, coupled with the abundant open spaces, make this an ideal kite-flying area. Surrounding farm fields with lowing cattle give Parkhill Prairie a rural north Texas ambiance.
