In reply to climbin_chris:
Hi Christ, I'm a fellow 4th year medical student, I'm currentley half way through my elective.
I know it's not abroad, but I've literally (yesterday!!) just finished a 4 week elective placement at the ED in Bangor, North Wales. I had an amazing time, and it's a fab location for climbing! I went out pretty much every day and just worked in the evenings, a benefit to working I. A department that operates 24hrs a day!
There was plenty of opportunities to get involved in things like Mountain rescue training days-I spent a day playing casualty for them! I also went to a pre hospital training day for the air ambulance,and there were loads of other things to do as well.
I was in the same position as you trying to find a placement outside of the UK like the one I have just done, in the end, I decided to stay as I couldn't find anything to match, I'm very glad that I did.
Have a look-

I start another 4 week placement on Monday with the Herts and Essex air ambulance, which will satisfy my prehospital experience desires
Wrt skiing, I was going to go to NZ but they no longer take students, probs the wrong time of year for you though.
If you want any other advice or have any questions, send me a message and I'll gladly help.
