An amazing Enduro track from Chandolin to Sierre (or Leuk alternatively)
> To be able to ride this trail in the future, PLEASE NO DOWNHILL-BIKES AND NO FULL-FACE HELMETS. Thx!

1a) Take the postal bus at the main station in "Sierre" or at the 4th stop "Sierre, Bois-de-Finges" near the end of the highway (Sierre-Est). > It's highly recommended to make a RESERVATION via www.resabike.ch (until 4 p.m. the previous day).
1b) Change the bus in "Vissoie" to "Chandolin, télésiège"
2) You'll arrive directly in front of the chairlift of "Tsapé"
3) After that, a short ride from the chairlift of Tsapé to the top of Illsee pass (20 minutes)
2) Start of the trail : the first part is really steep, rocky and very technical. It ends on the barrage of Illsee (Gorgeous view at this point)
3) Then, the trail is a little less sketchy but still technical with some challenging turns.
4) The entrance of the forest is just a pure pleasure ! Soft ground, great speed and magical slippery turns !

| ATTENTION | To avoid conflict with alpine herdsman and animals (cows), please RIDE SLOW when you arrive at the grazed alps "Obermäschlär & Unnermäschlär" (from 1600 m.a.s.l.). Be gentle to the animals & herdsman and DON'T LEAVE the trail.

5) Once you've reached the valley floor, you can cross the scenic "Bhutan bridge" over the Illbach river and follow a singletrack to go back to the bus stop.
6) Alternatively you can cut down to Leuk and take another bus into the south facing region of Leuk/Sonnenberge.
