The walk was well described on this site, I had printed off the map and it was paths all the way... just as well as there was thick fog for the whole trip! I did laugh at the description though - get to the end of the loch and climb the steps to the top, just like that! Given the poor visibility, I couldn't see the top though and hadn't appreciated just how many steps there would be, but I made it.
On the way back I decided to take the extra route round the loch even though I could hardly see it - figured it was safe to keep following paths. I managed to fork right sooner than I should have, so joined the path back at a point where there was no sign marked for Killiecrankie and wondered why my climb didn't feel as gentle as the description made out

White water rafting was also lots of fun - highly recommend it!
