In reply to trystan:
I remember a fun wall with some traversing on the river opposite the campsite (the smaller one, cant remember the name). I also did tonnes of deep water bouldering style stuff all along the river, however this was all accessed from a canoe so I couldn't really pinpoint where.
So sorry not much help but if you get a canoe/SUP whatever theres tonnes to go at if you keep your eyes peeled. We had an inflatable and either did bike drops, got buses or were clever with big meanders with short walks between river access points to get about.
Edit: I've added some photos, the first is at the campsite the 2nd is a little upstream from it. there was also some awesome stuff in the main gorge itself (of a similar short nature). the main hazard is not landing on other people in canoes.
