The Bonatti Rifugio is popular for good reason.
As well as being on the classic TMB (Tour du Mont Blanc), it's very comfortable by alpine hut standards and in a beautiful spot.
But you set off from this well known treasure en route to the well kept secret of the Petite Bergerie - a favourite with the locals in the Aosta valley. Follow the picturesque alpine trails to the Col Entre Deux Sauts and continue winding your way up to the increasingly alpine terrain of the Col du Bataillon.
From here the trail takes you steeply down to the Grand Plan and Chambave before winding back through the forest to the delightful Planaval, where you would be well advised to stay for dinner or even the night.
