Tub del Coll is Arinsal's most technically difficult run, with a high skill set needed to take on this tight and twisty run, which develops as the season goes.
On powder days this is a must as it's never groomed as is situated between two off piste areas, giving you the option to ski where you want in this area.
As the weather clears this run has the tendency to bump up, leaving irregular medium to big bumps for the most advanced skiers to ride.
The areas to the sides of the run, are rock banded so be careful for the small drops and shark rocks waiting to snag your skis from below.
This run sees little traffic apart from the powder days where it will get smashed up from first to last lift, so get there early to enjoy it in its best fresh powdery conditions.
