This is a shorter version of the Tour des Fiz where you still get to experience the Desert de Plate and the Refuge de Plate and see the views from on top of the cliffs above Servoz and Plateau d'Assy. The trail takes you from Plaine Joux to Ayeres des Rocs and then a very rocky and scenic route takes you to the very steep cliff passage of Derochoir. This is pretty spectacular with ropes and metal railings enabling you to scale the cliff and reach the top. Definitely not something you can do with young kids or dogs. From the passage du Derochoir you will have a nice view all around you. In front you will be a view towards Refuge de Sales and behind you a pretty great view over the Sallanches Valley and Mont Blanc. From Derochoir you will climb up to the Col de la Portette before descending to the Chalets de Plate. From there a fairly steep and rocky passage will bring you down from the cliffs and back to the plateau below it. From there its a horizontal traverse back to Plaine Joux. Overall a pretty diverse and spectacular route and a quicker way of seeing a large part of the Tour des Fiz

Risk Considerations & Difficulty Assessment
This route reaches an altitude of 2354m at the Col de la Portette. The route has highly technical parts and should really only be undertaken when the trails are completely snow free. The Passage du Derochoir uses ladders and ropes to make you scale the cliff face and you should never try this with snow and ice making this a slippery affair. I would generally recommend this route from mid June to the start of October but you need to check the conditions ahead of time. The Refuge de Plate could be a good source of local information if they are open. The trails are well marked and not hard to navigate. The main waypoints are Ayeres des Rocs, Derochoir, Col de la Portette, Chalets de Plate and Plaine Joux. The trails themselves are highly technical and the ropes and metal handrails at the Passage du Derochoir are probably the steepest I have experienced in and around Chamonix.
