Both Oxley (1818) and Sturt (1828) passed where the present town of Warren is located in their quest to solve the riddle of the rivers and, of course, the Macquarie Marshes are associated with the myth of the "great Inland Sea". Thomas Mitchell also explored teh lower region and the marshes. The early history is comparatively well documented and much photographic material is available from the Warren Library. The town was gazetted on 30 June 1861.

Fishing on the Macquarie River is a major recreational activity with abundant sites for camping, boating and canoeing. The National Parks and Wildlife Service organised camping tours in the Macquarie Marshes througout the year with people from throughout the State travelling to explore the wonders of the Marshes.

Close to town is the Tiger Bay Wildlife Park. The park is a natural overflow of the Macquarie River system and is home to many species of birds and aquaticflora. A walkway along the levee with binoculars is a must for any interested bird watchers.

The River Red Gum Walk in Macquarie Park is a pleasant tour of both historical and botanical interest. The walk follows the curve of the Macquarie River through an established parkland.
