Mesilla Valley Bosque State Park is a state park in the U.S. state of New Mexico that protects a bosque, or riverfront woodland, along the Rio Grande. The park is situated close to Mesilla and just west of Las Cruces. Its size is roughly 305 acres (1.23 km2), and its elevation is 3,900 feet (1,200 m). River woods and reclaimed marshes make up the park. Migratory birds use it, and people enjoy walking, biking, and birding there. There is no camping permitted here; it is simply a day-use park. The restoration, leisure, and educational goals of Mesilla Valley Bosque State Park are supported by a vibrant Friends of the Park organization.
