Depends on budget, like many of these things.
I’ve done Morzine/PDS many times, but probably won’t ever go back. I guess the one redeeming feature is its quite cheap & you don’t really need a guide.
For quality of riding in the local area for a week, Les Arcs or Verbier are both significantly better, but like most alpine towns, fairly ghostly in the summer & you will need guiding. Still in Europe, Finale Ligure totally blows away the PDS in my opinion. Take into account the town is on the beach, and it’s actually a busy, normal town, it’s a very different experience. I think there are more braking craters in one corner of one trail on the PDS than I rode in a whole week of Finale, earlier this month.
Further afield, Whistler/Squamish/Pemberton. Just because. It’s like Disneyland for bikers (and outdoor enthusiasts).
