During holidays the resorts and holiday destination places will be open. Finding a local grocery store open on a Sunday or holiday will not be so easy. Although again, in tourist towns, there are generally better opening hours even for grocery stores.

Places in the mountains like First will still likely be in winter mode with snow and probably not re-opened again for summer hiking until much later, if that is what you are looking at. In the Bernese Oberland where I go, last day of winter ski season is weekend of 9-10 April. Thereafter remain closed until re-open for summer hiking season which is typically in late May. All the seasonal openings should be on their website.

Easter in Switzerland is very quiet, we usually leave and go to Italy during this time.

Weather wise, it can be very iffy and no cliff walks will be open yet. The mountains will still be full of snow / hiking not an option unless you want to do winter hiking and have the gear for it.

The mountains aren’t full of snow now
