Best Answer
While I might opine that "uncrowded" is indeed the opposite of "crowded," much like "unintelligent" is the opposite of "intelligent," you explain your position well and I do understand your question.
The thesaurus gives these antonyms: deserted, empty, imprecise, loose, uncongested, unfilled, and, yes, uncrowded.
Looking at the synonyms for deserted, I find barren, derelict, desolate, empty, forlorn, isolated, lonely, neglected, uninhabited and vacant.
You may wish to wander around in the thesaurus and dictionary to find a word that feels appropriate in the context in which you're using it. I use this one.
