Description from East to West: Starting on the old train tracks that define the eastern border you'll follow the bike path down to lake Tuggeranong where you'll then follow the Murrumbidgee downstream along the Murrumbidgee corridor trail to the Casuarina Sands bridge. From here you'll start the climb up the fire trails into Brindabella National Park before summiting Mt Corree and completing the ACT East to West border crossing.
