best day trips out of lyon in march? (coming from aix)

asking this here specifically also because i'll be coming from aix, if there is a good place to visit kinda on the way (not perfectly on the way but reasonable to visit before reaching lyon from the south), it would be great to know! i was considering visiting geneva, which is outside france ofc but would give me an opportunity to see switzerland for a bit, or if there's a cute village in the french alps i'd be interested
