2 drop out points on that 16 mile trail at 8 mile mark. Try to do those early spring and not July like we did. Had kids and leaders get heat problems as there is no cover from that sun.
If you do go mid summer, the river may not be running high enough to raft or kayak. You can however head up to Huntington reservoir where there is plenty of fishing, kayaking to do. Also Joes Valley has world class climbing if you have crash pads.
