When I hiked in the Italian Alps in September 2020, I found that bivouacs (bivacchi) were mostly open, but their use was not allowed except for emergencies. For example, the Bivacco E. Marigonda above the Valle di Bognanco had a sign like this:
Transcription of text on the sign:
Bivacco inagibile causa emergenzia COVID-19.
Due to emergency no access to bivouac.
This was true for all Italian bivouacs I passed on my hike. The rifugi (staffed huts) were mostly open (and allowed to use with restrictions), but for some that were closed, the winter room was closed as well, despite normally being open year round.
Has this situation changed at all for 2021, or are the bivouacs still prohibited to use? The only official information I can find are for the Val Grande National Park, where use of bivouacs is officially prohibited (as of 17 May 2021). When I perform a web search for the literal text on the sign, I find mostly results from (spring) 2020 and very little on an update for 2021.
