Opening Hours · Seasonal windows
When each reading reads at its best.
Hours of operation, seasonal closures, light direction. The Alps impose a calendar; the calendar imposes the visit.
Most Swiss museums and lower-elevation sites are open year-round; alpine sites and mountain railways follow a season. Volume IV's readings span the full elevation range — from 372 m at Lavaux to 2,253 m on the Bernina pass — and therefore touch most of the country's seasonal patterns. The table below collects the editor's preferred windows.
| Reading | Best window | Avoid |
|---|---|---|
| Lauterbrunnen valley | May–October. Late-spring snowmelt produces maximum waterfall flow. | November–March (some falls dry; gondolas to Mürren closed Nov for maintenance). |
| Kunsthaus Zürich | Year-round. Tuesday afternoons quietest. | Monday (closed). Special-exhibition opening days are busy. |
| Lavaux vineyards | September–early October (harvest light). May–June for green terraces. | Mid-summer mid-day (heat on south-facing slopes). |
| Bernina Express | Late May to mid-October for the full open-window service. February–March for the snow line. | Late October to early December (line operating but with reduced panorama cars). |
| Lucerne lakeside | Year-round. June–September best for the lakeside walk. | Late Sunday afternoons in summer (cruise-boat congestion). |

Light direction by reading
- Lauterbrunnen valley. The valley runs north-south, framed by east and west cliffs. Morning light reads the west cliff (Mürren side); afternoon light reads the east cliff (Wengen side). Staubbach Fall is best at mid-morning.
- Kunsthaus Zürich. Interior; light direction is the museum's lighting design, not the sun.
- Lavaux. South-facing slopes; reads strongly all day, but late afternoon to early evening is the photographer's hour.
- Bernina. The line traverses east-west; both sides of the carriage receive direct light depending on bearing. Right side (southbound) is the lake-side at Berninasee.
- Lucerne. The lake faces south-east; the Pilatus massif is photographed best in late morning from the lakeside.
The Swiss calendar is a precise document. Plan against it; do not assume that an off-season visit will find the gondolas running, the mountain railways open, or the alpine museums staffed.
