Cattai National Park

The Cattai Farm area, originally a land grant to First Fleet assistant surgeon Thomas Arndell, features Arndell's 1821 cottage, historic grain silos and ruins of a windmill believed to be the oldest industrial building in NSW. In a separate section, nearby Mitchell Park features a variety of plant communities, including rare riverine rainforest.

Cattai Farm has grassy picnic areas, barbecues and shelter sheds beside the Hawkesbury River, and car-based camping is available year round (bookings essential). Mitchell Park has an extensive network of walking tracks, and there are picnic areas with barbecues beside scenic Cattai Creek.
