Col de la Frasse and Col du Plane


I received a nice comment from Colin recently on my Top 5 Cycling Climbs from Lake Annecy post.

He mentioned a road up to Col de la Frasse that I had never heard of – so i got the maps out and made a plan.

I started near Annecy – with 10 kms alongside the lake on the cycle path. A few hundred metres before the cycle-path tunnel and before Duingt there is a little right turn. The climb starts here (see map below).

It’s a charming climb – fairly steep through woods and pasture. The climb lasts 10 kms on a good surface – a great little climb for a road bike – requiring a U-turn back down as the paved road ends at about 1150 metres. But for me the adventure began here.

There is a Grand Randonée hiking route here. To be clear – even with a mountain bike – it is
not ride-able. So I just pushed my hybrid and hiked along a VERY muddy/steep trail for the last 1.5 kms to the Col.

My plan was to go over the top and down the other side. So another 2 kms of steep descending/hiking with cow bells ringing everywhere until I ended up in Mont Derrière or in English: Bum Mountain (ok, a rather loose translation).

I was now in the Bauges Alps. Sparsely populated, green, rolling roads. Really nice cycling. I took a quick detour left on a deserted dead-end road to climb Col du Plane. I met a road cyclist – and sensed he was a bit disappointed when the paved road ended – I rode the last 2 kms on ride-able gravel trails to the Col without him .

At the Col, a u-turn and a fast return to Annecy via Col de Leschaux with views of the Lake.

Thanks Colin for the suggestion!

Happiest while cycling uphill.


  1. Rode up this today, hotel is at the base of the Entrevernes hill. Part of my training week is 3 -5 climbs up the the top of the Village where the road then climbs to La Frasse. Today i rode it and was also gutted the road ended. You are right, its a pleasant climb but saw a few mtbers at the top.
