Starting from the southern end of Sleaford Mere off Sleaford Road, Lincoln National Park, this walk takes you to the main park entrance. This moderately challenging bushwalk initially winds along the shoreline of Sleaford Mere, a picturesque permanent saline lake named by Matthew Flinders in 1802, then follows a trail through shrubland to the main park entrance. The lake provides feeding habitat for numerous waterbird species, including the chestnut teal, and fosters an environment that allows microscopic organisms to form stromatolites, which can be seen along the water's edge. The walk is part of the Investigator Trail, a long-distance walking trail consisting of several shorter connected trails within Lincoln National Park. This walk consists of wide, mostly flat walking trails and fire tracks, with compacted natural surfaces, suitable for average fitness levels, and can be done in either direction. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.
