I took a different route, parking the car at the far end of Lochan Na Lairige and making it a horseshoe route around the valley.
The horseshoe route I was going to walk

Parked the car in the wee carpark at the end of the Lochan

Looking down on the Lochan Lairige and road

Looking upwards to the first and only munro of this walk - Meall Nan Tarmachan

The views from the top are rather good - Ben Vorlich and Stuc a'Chroin

The route ahead with Ben More and Stobinean in the distance

Well defined route with a lot of up and down

You get pretty close to Killin

THAT steep descent - quite scary on your own

A look back at the steep bit
