Three of us met at 7am at Mittagong and after dropping one car at the finish and meeting with Eric at the put-in, we set off at 9. After about an hour of races and some log dogging, we got to the first gorge starting with a nice 2-stage grade 4.
Portages are fairly easy over the bouldery banks.
The golden rule of inspecting from the bank where you can't see paid off when we found a well hidden log all the way across at the bottom of a small drop running from river left to right. We also found remains of few open plastic canoes, few paddles and a PFD - proving that this is not an open canoe trip. The river is surrounded by steep cliffs so walkout would be very difficult if not impossible. The only way would be to follow the river which would be very lengthy. An emergency overnight gear might be a good idea.
