We nearly turned left to do Sa Calobra after Puig Major, but I did it the day before so didn't bother.......3 of our team dropped down to Des Canonge and Port de Valdemossa. They did stop for lunch but got back to the hotel around 6.45.
If you're going to take in Sa Calobra as well, then:
1. Good luck
2. You're crazy
3. I'd take some lights with you!
But enjoy anyway!!
