We drove over from Kenmore in good time then wasted about 20 minutes driving up and down the road between Crianlarich and Tyndrum trying to find the correct layby near the turning for Kirkton Farm. That was down to me being dozy and not seeing the sign when we passed it - although in my defence Kirkton Farm is only mentioned on about the third line down.
So we finally got going and walked up the Kirkton lane to a bridge over the River Fillan.

After crossing the bridge we followed the track to the farm and turned left just before it, briefly joining the West Highland Way where we met the only other folk we saw all day - a couple on holiday from the USA. Almost immediately after joining it we left the WHW for a track to the right, passing an old cemetery with two large trees.

This track leads to a level crossing over the railway line.

Once over the railway line we left the track for a very faint path uphill towards the deer fence.

Kirkton Farm is doing an experimental regrowing of native woodland so is being careful about keeping sheep and deer out and if we saw any in the section between the high stiles we were asked to report it. We didn't see any.
Ben Challum gets quite a bad press for its soggy approach and we did get a taste of that with a few large muddy patches to be avoided but it wasn't as bad as I expected and we were thankful not to be climbing it after a spell of wet weather.

It was hot work climbing so we had a few rest stops which was no hardship on a day like this as views opened up on every side.

We both enjoyed the cleft ridge at the south top with a little bit of rocky narrowness thrown in for interest.

After the south top there's a slight descent before the final pull to the summit.

We hadn't finally decided what we'd do the next day but seeing Ben More and Stob Binnein looking so stunning clinched it - we were heading their way!
