Col de la Brèche Mountain Bike Trail

Highlight (Segment) • MTB Park

This sturdy climb is on a wide gravel path with fairly thick stones. The route mainly runs through the forest, but you still regularly get to see very beautiful panoramas. This path takes you to the foot of the Chatèl.

It's an ideal starting point for the hike. There is a shelter to have a snack, and it's a few minutes from the Sainte-Luce farm. In spring it's a known spot for flowers and particularly daffodils.

An easy pass, away from traffic, in the very heart of the Alpe du Grand Serre Station. From Séchilienne, approx. 15km for D+ 1000m. To do in summer to enjoy the freshness of this shady slope.

Col can be VERY steep, especially from Entraigues. On the other side it is more lenient and accessible.

I added the SAMBY to avoid a round trip of the existing proposed hike in Visorando Departure in the Undergrowth by a forest track, it climbs well up to the Col du Plan Collet. on the left towards the CAVALE by the long ridge. on the right the SAMBY for the return by a path in the forest. nice view of the OBIOU, the triève, a superb view also of the summit of the Coiro in June, the flora is extraordinary the descent through the small valley all in bloom in JUNE really made you want to venture there I opted for a picnic at the edge of the small torrent using the ends of existing paths the path then is quite visible in the middle of the valley ps: as often by turning around from half of the valley we can clearly see the route when you reach the flat valley, you find old round walls and chamois the path is dotted from here on an old map to join the path of the climb continue the path skirting the hill and following the path sometimes clearly visible, sometimes it disappears some cairns still remain, I straightened them (the lilies of St Bruno dot the meadow) we join the path of the climb of the 1st stop we descend to the Col du Plan Collet

The Col de la Morte from Sechilienne is 15.3 km long with a total drop of 1003 m. The average gradient is 6.56% with maximum gradients of 9.3%. A very nice climb to do during the summer months because the climb is mostly in the shade. When you get to the top you can go down the other side to La Mure.
