When to go
May to September is the easiest broad planning window for a mixed group, because lake bathing facilities, outdoor sightseeing and local scuba can be combined.
Best overall window
Most practical period for lidos, lake-centered sightseeing and combining a shore dive with an outdoor day. Check each attraction's actual opening dates.
Outside that window
Focus on town, museum and selected winter mountain activities; cold lake use requires purpose-specific skills, and some attractions follow reduced schedules.
Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
