  The Roman roads

  More than just a tourist attraction, the Roman roads were one of the main routes used to cross the Alps in ancient times! Before the Roman invasion, the Ceutrones, a Celtic tribe who farmed livestock, inhabited the Val-Montjoie. To make cheese, they used salt mined at Moutiers via the Col du Bonhomme. They were involved in building roads to Italy. These roads were taken over by the Romans when they invaded the Alps. Take a look at the Rochassets pass: it was carved out of the rock to allow chariots to pass through!

  Flora

  Rosière boglands

  On your left are the Rosière boglands, but be careful to only admire them while walking along the path, as they are fragile environments and hidden treasures of biodiversity! Tracing its origins from the Ice Age, this boggy area is the result of a glacier erosion which caused water to stagnate. This is the kingdom of carnivorous plants such as the Alpine cattail or the round-leaved sundew...

  Flora

  The round-leaf Sundew

  It is a small carnivorous plant that lives in low-nutrient peat bogs. Don't worry, it only feeds on insects, which it attracts and digests using a viscous substance produced by the red bristles that cover its leaves. It is also known as " Rossolis or Sundew " because the substance sparkles when exposed to light. This species is fragile and protected, please do not touch it!

  Small patrimony

  The Roman bridge

  Also known as the "Téna Bridge", this structure dates back to Roman times! It is located on the strategic route used at that time to reach the Tarentaise valley and Italy from Les Contamines. This route, which has since become the famous long-distance GR5 hiking trail, is a popular tourist attraction. The bridge overlooks the gorges of Bont nant. Marvel at the pools of water that the waterstream has sculpted over the years!

  Hay meadows of la Laya

  Formerly mown and grazed, these meadows have slowly turned into woods since the abandonment of all pastoral activity. Shrubs and spruce have gradually colonised these former meadows. This is known as the closure of the environment, endangering certain plants such as the Golden Oat, a favourite snack of the livestock, and the Alpine Colchicum. Since 2014, the Nature Reserve has been clearing the undergrowth and mowing the meadows regularly in order to restore their function as summertime pastures.

  The Alpine Autumn Crocus

  It's the end of summer... This is the time of year when the Alpine Autumn Crocus blossoms. Its name comes from Colchis in Greece, home to infamous poisoner Medea. This plant contains a highly toxic alkaloid: colchicine. According to the alchemists, this substance, when used in very small doses, could be used to treat rheumatism and episodes of gout.

  Geology

  Combe noire waterfall

  When you stop at this bridge, you can feel the fresh spray from the Combe Noire waterfall and just imagine that the Tré-la-Tête glacier arrived here in 1870! Since then, the glacier has melted a few hundred metres, but its presence can still be felt through the raging river, which has formed impressive sculptures known as "potholes of giants" as it erodes the rock in a thunderous racket!
