Horsnell gully track is quite rough, blackberry bushes scape at you and you can lose your way quite easily. The river bed is steep and tough especially at the 500 metres. The walk back down is nice, along the Heysen Trail fire track mostly. Be prepared for approximately 2.5 hour hike, with rock climbing! Not really suitable in winter if flowing. Bring water, jeans, sturdy shoes and a phone for great veiws! read more
