My vetter said don't even think of trying the south shore (I wasn't as it happens) and fording the Choilich could tricky when inspatw but could be possible further upstream.

I think Alan's got it right. Heading for Loch Mullardoch S.side, I
went instead up the west side of R.Choilich,crossed at approx. NH095 252
without much problem and headed over Bealach Coire Ghadheil,down
into Glen Affric and Cougie for scones and bacon sarnies.
Another time I reversed the route along the E. side of the R.Choilich
and camped at the junction of the river and the Loch for four days.
On flat well cropped ground(deer),near the Old Bothy
I did try the S. side of the Loch but gave up because of slow going.
There was in places signs of a vehicle track along there. Cheers.

Hi Terry

I have crossed here without any difficulty and although I didn't note it I think there was a vehicular ford here. If it's in spate it could certainly be a problem You also have another possible problem with the Allt Coire an Lochain where, the same year, I had to do a lengthy detour upstream to find a safe crossing.

Alan

Have a look on Geograph and you will see the ford Alan refers too. As he says there are other burns which could be really serious in spate, although some are shown as having bridges who knows if they will be there when you need them.

hi there grumpy geograph what a great site thanks. seems like i mite be on an adventure going that way!!!!

I remember Dave Williams from Sheffield went that way a few years back and when he got to around Beinn Fhionnlaidh he got stuck but managed to get a lift in a row boat with a fisherman over to the north side where we all were beneath An Socach. It looked fairly impassable. If it was a fine day you could go along the ridge though that might depend on which end of Alan Sloman's graph you are located.
