Thanks all. We walked to the falls from Camas-luinie today and they were indeed very impressive.
No problems at all with the burn crossings, but plenty of water coming over the falls.
As Paul says, the path along the south bank before it joins the Killilan track is quite wet at times, but it was quite scenic and probably did save some time, which was useful as we were walking elsewhere earlier in the day. With a bike the Killilan route would definitely be much better!
There were several cars parked at the Killilan car park as we drove past, but we were the only ones starting from Camas-luinie. A sign of just how popular WH is nowadays?
The path up to the falls was quite busy with Cape Wrath Trail hikers.
