They don't take credit card so make sure you have cash! 12chf plus 5 chf for skate rental.

Aside from that... what a wonderful experience! I've skated in many places but have never done anything like this before. It's a lovely ice track in the woods, and it's a long circuit so you can go round and round at your leisure. There are two slightly downhill gradients, not very steep but you pick up speed surprisingly quickly! Quite scary for a beginner but everyone seemed to cope okay.

I think the ice is best first thing in the morning, as (I assume) they only resurface once a day, in the morning before they open. I thought about going later to get some sun on the trail but I'm not sure the sun reaches this part of the valley, it hadn't by 1pm anyway. So go early if you can, but I'm sure it's nice all day.

You can leave your bags and shoes in the changing hut. There's no security there (no lockers) but my bag was totally fine.

The only thing I'd want to make it better was if there was a little stand selling mulled wine and hot chocolate, that would have been amazing.

The bus there and back is hourly and matches up nicely with the trains at Scuol-Trasp. There's a restaurant near the bus stop if you want to wait in the warm for a bit. The bus gets incredibly busy on the way back when all the skiers board at Sent!
