Surefire Canyon is an excellent trip but it involves a long walk in and out. Up to 20 klms for the day. There are 5 short abseils but they have tricky starts. There are several wades and one possible short swim. The exit is tricky with several climbs up tree roots, rock walls and trees. Ropes will be needed to assist in the climb out. An early start of 0800 will be required as this will be a very long day.
