I also have two active boys, and I have been looking at the Tauck Bridges Alpine Adventure itinerary. It seems to be *very* active.

Here are some of the active components:
Switzerland's biggest rope park*, the country's longest summer toboggan run*, or a thrilling (but safe) giant tubing slide!*
Then it's off to the Morteratsch Glacier for guided mountain hiking*, rock climbing* and abseiling* (descending via ropes)... a visit to an Alpine cheesery for lunch in a meadow and a look at cheesemaking... and a few surprises!* If you wish, hop aboard a mountain bicycle* for a ride back through the Engadin Valley to St. Moritz,
The afternoon takes you to Innsbruck's high-tech Bergisel ski-jump complex, designed by star architect Zaha Hadid, for a demonstration of the difficult and daring art of ski jumping. Then it's on to your Alpine spa hotel in Längenfeld – the AQUA DOME – offering aquatic fun for the whole family with a pool, waterslides, spa, sauna, thermal baths and fitness center.
during a trip to Area 47, one of the largest adventure parks in the Alps, and Europe's ultimate outdoor playground. Jump into a neoprene suit and helmet, and head out on a whitewater-rafting adventure*; then do some swimming or try out the slides and other attractions of one of the newest and biggest water parks on the Continent.
Depart Austria and cross the German border into Bavaria, where you'll arrive in the village of Ettal this morning for your choice of a guided mountain hike of the area with a park ranger, or a visit to Ettal Abbey.
