Starting from the carpark behind Turramurra Cyclery, we head up the Pacific Highway through Hornsby to Galston Road at Hornsby Heights. We descend through Galston Gorge and then climb out the other side to Galston. At the first roundabout we turn right and head through Arcadia and Berrilee to Berowra Waters. There is a steep descent to Berowra Waters Ferry. We cross on the ferry and then climb out to Berowra. We turn right at the Pacific Highway and then ride back towards Hornsby. At Mt Colah we turn left to Bobbin Head. There is another steep descent into Bobbin Head where we cross the bridge and then begin the climb out to North Turramurra. From the Toll Gate on Bobbin Head we follow Bobbin Head road back into Turramurra and then to Pierre's Patisserie for a well earned coffee.by screid
