WOW, this was my first group hiking experience and I was not disappointed! Collett's offers total flexibility: arrive/depart when you wish, 3 levels of guided hikes offered daily (all trail-heads accessible via bus service), a thick 3-ring binder with hundreds of hikes if you'd like to hike on your own, AND knowledgeable, friendly staff. I stayed at Chalet Verena in Corvara. It was centrally located, within easy walking to all services in town. The room was spacious, food delicious and pleasantly presented and the chalet was very clean. One of the nicest features is the Office Hour in the evening when staff are available to ask questions and help plan the next days activities. I stayed 9 nights and thoroughly enjoyed the holiday. Best of all: THE STAFF. Big thanks to everyone at Chalet Verena.
