Years ago my wife and I rode the carriage trails at Acadia NP on road bikes with 23s
Definitely would have been more enjoyable on MTBs or current gravel bikes. There was no plus side to it, IMO. More recently I've tried local "gravel" rides on 32s. Would have been OK if I was riding alone. With a group, it meant I would catch up on the climbs and drop back on the downhills and creek crossings. No virtue in having the wrong tool for the job.
