The Parc National des Grands Jardins is a huge, beautiful place for hiking and climbing, but I'll…read morefocus here on an attraction that's new this year: the Via Ferrata. It allows you to, well, mountain-climb; travel straight across mountain cliffs (the mountain is the Mont du Lac des Cygnes) held by a harness that you clip to a system of steel cables, handholds and footholds that span the mountain. You are, uh, high up, like 700 meters. It's a gorgeous view for those inclined to look around. It's not really dangerous in the direct sense, since you clip and reclip the two connectors from your safety harness to the handholds and cables as you travel (at least one is attached at all times). There are excellent guides (ours was named Caroline) who give you a little lesson beforehand and stay close to you throughout the proceedings. They take people from age 12 up, and many kids and adults scramble happily along the mountain. Some people, however, might be perturbed by the concept of being 700 meters above nothing, held up only by the above-mentioned apparatus (in fairness, they're brand-new harnesses and really solid wires). One highlight is a "Nepalese bridge," where you cross a gorge walking on a single cable (but with two other cables to hold on to and your harness solidly clipped to another). It's a great experience if you like this kind of thing and the feeling of accomplishment afterward is terrific! (Definitely safer than crossing the Grand Canyon on a tightrope.)
