Trying to travel light on an extended European tour, but I don't want to miss out on hiking b/c of not having gear. We're going to be in the Jungfrau for a week in the first half of June and would like to do several hikes (1-5 miles, max about 800 meters elevation gain).
How cold do we need to be prepared for with day hikes? Definitely bringing rain pants which help with warmth, and will have light gloves, warm jackets, but torn on taking a polypro fleece pant or not.
Also would Yaktrax be helpful? Are trails just closed if there is still snow, or are there hikes where there would be melting some icey spots where traction could be handy to have? Are these (or similar) items widely available for sale in say Wengen?
