We went 10 years ago so, man, are we young! And memory is a bit cloudy...
Oastler is right next to Hwy 400 just south of Parry Sound
on a small bit of land amongst lakes and bays. It is very pretty but campsites
and facilities are closely arranged, and there isn't a lot of privacy between sites. It has a small beach but excellent swimming, and seems like there is likely good fishing too. A bit of a drawback is that trains go by sometimes, including through
the night and they can be quite loud. This park also coordinates camping for The Massassauga Provincial Park which is back country camping towards Georgian Bay.
