Summer in Lech
The lifts stop in late April and the village exhales. The summer season runs late June to mid-September, and it is a different place: a fraction of the winter's visitors, meadows where the pistes were, and a pace that makes the long lunch look hurried. People who only know Lech under snow tend not to believe the photographs.
This is walking country first. The Lechweg, the long-distance trail that follows the river to the Allgäu, starts at Formarinsee, once voted the most beautiful place in Austria and an easy day's outing even if you walk no further. The Green Ring is the summer counterpart to the White Ring, a three-day circuit above the village that can be broken into single days, and the guest card covers the summer lifts and the village buses, so height is cheap. Swim in the Zürsersee if you can bear the temperature.
Two fixtures shape the calendar. In late June the Arlberg Classic brings pre-war cars over the passes, and in September the Philosophicum fills the village with a week of lectures and a distinctly un-resort-like crowd. Book around both if you want quiet, or into them if you don't.
A practical note: fewer hotels and restaurants open in summer than in winter, so check before you count on a particular kitchen. The reward is that nothing needs booking weeks ahead. That alone tells you what season you are in.
