Allestree is the northernmost ward of the district of Derby and as such its northern and western borders are mainly countryside as the ward gives way to the district of Amber Valley. The border with Darley to the east follows the A38 from Ashbourne Road roundabout up until it crosses the River Derwent. The border then follows the river then crosses the A6 and follows the border of Allestree Park. To the south the border runs along Ashbourne Road from the A38 to Markeaton Lane until it meets Markeaton brook, which it follows. It then runs along Kedleston Road which it leaves and goes behind Woodlands Community School and Laburnum Crescent and finishes at Allestree Park.
