I haven't done the whole loop, but ride the path along the river from NOTL to Niagara Falls and back at least once a year, it's a very nice route. Nice views, pretty houses to look at, vineyards on the other side of the road. All on an off road path. The ride is 25 kms one way, and the only real hill is on the way to Niagara Falls, at Queenstown, I think. The Botanical Gardens are very nice, Butterfly Conservatory well worth a visit.
There's lots of nice B&Bs in NOTL. They're on an expensive side, but usually pretty nice. The one we stayed in is not a B&B anymore so can't make a recommendation, but have a look on line.
Also many nice restaurants, but we usually stop at the pub after the ride, Angel Inn is right downtown Niagara-on-the-Lake.
I will make a note of a Stone Road Grill, thanks Boudicca!
