It's a beautiful area. I spent a couple of weeks there with my ex. She was a non climber, but had plenty to keep herself occupied in the valley whilst I took myself off for a couple of 2/3 day climbs in the high mountains including Piz Bernina 4,049m. Apart from this we did loads of scenic walking and cycling together and we did one easy, virtually glacier free, peak called Piz Morteratsch 3,796m, her first ever Alpine peak. Non technical and fun.
