I have use of a rental car on my first full day in Quebec City and figured I would use it to visit the Ile D'Orleans, Montmorency Falls and the Beaupre Coast (if time permits). How long does it take to complete the circuit of the island seeing a few sites along the way? I'll be visiting on a Sunday, so I imagine many places will be closed, but are there any "must see" stops? Do you think I'll have time to factor in a visit to St. Anne-de-Beaupre after seeing the island and the falls? I will need to return to QC by 6PM.
