The falls are illuminated Nov. 16 to Dec. 30, 5 p.m. until midnight and Dec. 31 (New Year's Eve) 5 p.m. to 1 a.m.; January 1 to 16, 5 p.m. to midnight; Jan. 17 - Feb. 28, 6:30 p.m. to 10 p.m. and March 1 to 31, 7 p.m. to 10 p.m.
There is designated parking right across from the falls. If you make sure parking attendants realize you are disabled and need extra space to be close to things, they'll lead you to the special areas for vans and vehicles with ramps. There is a ramp that leads from the parking lot down to the road, you cross at the lights and there it is, Niagara Falls. There is also limited wheelchair parking upstream a little in front of the horseshoe shaped driveway leading to the Niagara Parks Police building. A common-sense tip: If you visit Niagara Falls off season during the week, you'll find parking much easier than during high season weekends. The falls themselves are one of the most incredible things I've ever seen. There are three falls, the Canadian Horseshoe Falls, the American Falls and Bridal Veil Falls. You can see them as you roll along the beautifully groomed pathways that lead you along the Niagara Gorge. It's an easy roll despite the many visitors from all over the world walking alongside you.
If you are seated on a scooter or in a wheelchair you may have a problem seeing through the wrought iron barrier around the gorge. The best place for seated visitors is on top of the Maid of the Mist Centre not far from the falls or on the second floor balcony of Table Rock House. You can take pictures and really see the entire area from your vantage point at both of these places. It costs nothing to view the falls and the true wonder of the volume of thundering water is something you'll likely never forget. If you are visually impaired, I'm betting you'll be able to feel the sheer magnitude of the place and the moving water by just standing in front of the falls. The mist coming from the roaring water can also leave you pretty damp at times. There is one place very near the edge of the walkway close to Table Rock Restaurant where the Canadian Horseshoe Falls rushes by only a few feet from where you're standing or sitting. I'll never forget leaning on the barrier staring down into that vast torrent of deep green that could so easily take me to my death and thinking how lucky I am to be alive.
