Pararaha Cowans Stream Bash

Start by heading up a climb to the highest point on Buck Taylor Track from the carpark. Short climb before you start the mainly downhill (with one more climb) to the coastal lagoons of Pararaha Valley. You'll pass Zion Hill Tk and Zion Ridge Tk on your right (ignore these and follow Buck Taylor to the boardwalk with Pararaha Valley Tk (turn left here).
Follow the Pararaha Valley Tk up to the Pararaha Shelter (and a toilet). At this point head down into the Pararaha Stream. From here it's a challenging route only without much running but a great adventure. Follow the stream up through many boulder hops, scrambling over boulders, creek beds and some hands needed here to scale rock on each side of the gorge. Keep an eye out for pieces of track on each side (they come and go) but mainly follow the track. You'll come across a couple of waterfalls that you need to use a track on the left hand side (looking upstream) of the valley to scale around the side of. You'll pass Walker Stream on your right. You'll also pass over a log jam and large boulders in the valley.
Eventually after an hour or two (depending on your speed) you'll see a small junction where the track forks left or right (left takes you up Pararaha Stream to Odlin Timber Tk - much shorter and less waterfalls) and right (looking upstream) takes you up Cowans Stream which continues on in the manner you have been (waterfalls, rock pools etc). The right hand Cowans Stream option is the better - much like the Jurassic Park like country you've just been up. You'll come across a couple more large waterfalls (the first has a bypass track on the left), the second (has a large log halfway in the falls - see pics) has a bypass on the right. After the waterfall the stream flattens out a bit and eventually you'll meet the crossing for Odlins Timber Track - take this track left (looking upstream) and follow it up a short climb before a longer downhill to Pararaha Stream. Go straight across for your last climb that leads back to the carpark. A great adventurous course.
