Located between Hastings and Mount Martha, this 1,005 hectare reserve surrounds the decommissioned Devilbend Reservoir and the smaller Bittern Reservoir. It protects a significant area of native vegetation and cleared grazed land, as well as providing a valuable habitat for birds. The main picnic area is located at the northern end of the Devilbend Reservoir which has been stocked with trout and perch. There are designated fishing areas, fishing platforms and walking tracks near this picnic area and also along a section of the Bittern Reservoir.
This historic property includes the graceful Briars Homestead which was built in stages commencing in 1848 and is open for public tours. The park also includes a visitors centre, vineyard, nursery, restaurant, and a large wildlife reserve featuring wetlands and bird observation hides. There are number of walking trails through the wetlands, woodlands and pastures.
