My boyfriend and I biked from NOTL to Niagara Falls area near the Rainbow Bridge. It was 24 kilometers or about 15 miles. Very ambitious of us but you can stay on the Niagara Pkwy the whole time. I would recommend driving to the falls only because once it turns into River Road the trail is over and you have a windy road to travel with many tour buses flying by you. It is extremely beautiful though and worth biking for a day somewhere along this trail. I found the way back (mostly downhill) to be exhilarating. Plenty of parks to picnic in if you decide to pack lunch. Rented bikes in NOTL at Zoom for $30 a day, which included a basket, helmet and lock as well.
