We'll be in Paris in August, and would like to see one of Loire chateaux. We'd like to use public transport, but my quick search shows that most of them are within 2-3 hours from Paris, which sounds a bit too much for a day trip. (Maybe I'm using Google route planner in a wrong way?..)
Are there chateaux within 1-1.5 hours by public transport from Paris? Bonuses would be if it is more a castle-like chateaux, not palace-like, and if there are other places to see/to do nearby.
Daytrip castles outside Paris is a close match, but that question is 10 years old, I suppose that public transport connections has changed since then.
