Mission Tejas State Park, State park in Houston County, Texas

Mission Tejas State Park is a 660-acre (270-hectare) park on Texas State Highway 21 in Houston County, within the Piney Woods at the northern end of Davy Crockett National Forest. It holds a commemorative reconstruction of Mission San Francisco de los Tejas, the Rice Family Log Home, a CCC-built pond with dam and spillway, and a fire lookout tower. Loblolly pine dominates, and the Sentry Pine is over a century old.

An early Spanish mission post was founded nearby around 1690 and served the Nabedache people before being abandoned after a few years. Later, the location became an important point along the major trade route connecting Mexico with northern Texas.

The Rice Family Log Home, built in 1828 by settlers from Tennessee, was expanded twice and finished by 1838. It served as an inn for travelers on the El Camino Real de los Tejas. Moved to the park in 1973, it retains original 1890s wallpaper and paint and is about 80% original.

The park offers over 17 camping sites with electricity and water, plus group areas near San Pedro Creek. Visitors should wear sturdy footwear on the trails and be prepared for seasonal weather shifts and insects, especially during warmer months.

The park holds an original segment of the El Camino Real de los Tejas, the overland route from Natchitoches, Louisiana, to San Antonio. Visitors can still see the swales cut by wagons and carts. The Rice Family Log Home inside the park served as an inn for travellers on this road.
