Thanks to another post, I just discovered that Switzerland has some nice cherry blossom trails. Having lived near the Tidal Basin in DC for over two decades, the idea of photographing Swiss cherry blossoms sings to me. In my quick research, I've only seen general "mid-April" and "late-April" suggestions for timing. Based on the below (admittedly broad) itinerary, can anyone suggest some towns, trails, regions, etc. where cherry blossom "peeping" and photography might be possible. (I know it is not exact science -- Mother Nature does as she pleases!)
First two weeks of April -- Lake Geneva and French Alps
Third Week of April -- Valais/Southern Switzerland (Brig, Visp, Martigny, Zermatt)
Fourth Week of April -- Ticino (Locarno, Lugano)
Last days of April and first week of May -- Lake Zurich, Zug, Lucerne
