Which courses you can do depends on your level. It is always better to understate your ability in the mountains if you are at all unsure, especially since if your level is not up to standard it could result in you being removed from the course with no refund offered.
Trips are either based out of the UCPA centre, doing 'day tours' and coming back to the centre, or they are 'hut to hut' trips whereby you ski from the UCPA centre to a mountain refuge and so on. There are a couple which are similar to the hut to hut but they stay in hotels/hostels and BnBs.
For those new to ski touring, start out with any of the 'Introduction to Ski Touring' courses, the trips go over the basics and give you the foundations to develop your ski touring on top of.
