What is a good place to camp in Philadelphia?

Looking for a last-minute place to camp in Ontario near Toronto or Kingston or between

• We're looking for a place to camp in Ontario either near Toronto, or near Kingston or inbetween the two - last minute (aka tomorrow or the day after), probably car-camping. Due to other plans falling through, we are trying to take a last minute camping trip for a few days before spending the weekend in Kingston (coming from Toronto). Ideally, we would like to camp in the wilderness, but as we are travelling with a disabled person (mildly intellectually and physically disabled teen) and a not very fit older person (mid-fifties, overweight), we aren't able to do any serious hiking or canoeing to the backcountry sites that we are familiar with. Also, it being the long weekend coming up, just about every single provincial park we have called is booked solid. So we are looking for suggestions for any sort of place to camp - provincial/national park, conservation area, town campground, private campground. More private/wild is better, but we understand that we'll be limited in options. We need a place that we can drive to, or at least where the walk in is less than 1/2 hour. But we don't require any kind of amenities - we are happy without electricity or running water. We have the equiptment to get by without anything being provided (water pump, camping stove, etc). Ideally, there would be a river/lake to get water from to pump clean and to swim in. Also, if we can't be in the middle of nowhere, being somewhere historic would be awesome (our Kingston plans already include a night sleeping at Fort Henry in the 19th century barracks).

• Answer:

  Just to be clear, you checked and Sandbanks Provincial Park is full mid week? If that's the case I suggest Silent Lake Provincial Park. Its a bit north of where you are but a quite "rustic-ish" car camping location (bring bug spray).
