Myself, my husband and our 3.5 year old will travel from the U.S. to St. Moritz to spend a week with our Swiss and German relatives the week of March 16-23rd. We have been so fortunate as to have lodging and car details taken care of for us. However, most of our relatives will ski during this trip and we will not. We spent time in Sils (before our child joined the family) and enjoyed hiking in the Engadine. My question is what type of hiking is available in March? Is is mostly hiking on snow trails? Is there snow on the floor of the valley around the lakes in March? We are trying to pack as light as possible and wonder if we will need snow boots or if waterproof hiking boots will work? Any other suggestions for enjoyable family activities would be appreciated! We enjoy hiking/walks as well as cultural (music and art) activities. Thank you.
