Re: Vallorbe Caves compared to St. Beatus Caves
I have no idea about St. beatus caves, but I went to the Vallorbe ones quite a few times and they're quite nice. You can go pretty far in the mountain. But it takes only 2 hours max to complete the tour, so you'd better add things to see to the trip to make it worth it. The Jurapark is not far, for instance.
