There is very little action for the first l0km. At Map Ref. 101180 Kingstown the river begins flowing through the spectacular Namoi Gorge. The granite gorge which forms the riverbed is cracked and broken, forming rapids consisting mainly of long, technical boulder runs, although the odd clean slab formed drop is encountered. There are plenty of excellent campsites virtually all the way along the river. The rapids are mainly long rock gardens, some of which require inspection, until approximately at Map Ref. 975190 Welsh 1 :31800 or 057190 Welsh 1:25000 where the river turns a sharp left just prior to a major rock face. There is a major grade 4-5 rapid with an angle slab of rock at the end of the last drop. This rock is capable of splitting plastic boats so take care. About 200m later there is another Grade 5 rapid which at higher levels is extremely dangerous. Much of the water is sucked underneath rocks on a very sharp turn in the rapid itself. About 50m later there is another major rapid, the best run being a drop of about 4m on the right-hand side. There is a rock at the very bottom of this drop. From this point, for approximately 2 or 3km, are almost continuous Grade 3 rapids that do not need to be inspected by experienced paddlers. For several kilometres the river eases up although there are intermittent rock gardens. The Glenbarra Falls are encountered at Map Ref. 929183 Welsh 1:31800 or 014183 Welsh 1:25000. This is a major cataract falling over two enormous rock slabs. It is an easy portage on the left-hand side (the writer doubts that too many paddlers will be terribly interested in a paddle especially at higher river levels). From the Glenbarra Falls there are still rock gardens and rock slabs to be negotiated although the river generally flattens out below Billy's Hole. From there it is still several kilometres to Lowry Crossing. Get out at the Warrabah Camp ground and save an hours driving and flat paddling.
