This was our first time camping in one of the Provincial Park in Ontario. I had to booked 5 months ahead to get a site and even then they were almost fully booked. I got the site without the electricity! It took us 5 hours drive from where we live! We settled down okay and survived without electricity. There was a washroom near our tent and the shower you have to drive maybe about 3 minutes. It was nice and quiet site and we love it except for the mosquitoes.lol I guess you can't escape with mosquitoes when you are in the wilderness.
