We just got back from this park, We were there 4 days. Link to Oastler Lake. Our campsite was nice- lots of shade, large good privacy. The campground was well maintained- staff were friendly. Lots of amenities nearby in Parry Sound. Beach was okay- but just off the highway. They had a TINY beach in the campground were pets could swim off leash. Also lake filled with all kinds of fish- great for kids.
Downside- there is a train that goes through the campground. Not a small train but trains that run on night long that feel like they are on top of you. I didn;t get a wink of sleep. For this reason I could not recommend this campground or ever go back.
I have never been to nearby Killbear Provincial Park but if I have to back to the area- this is where it will be.
Our next trip is to Awenda Provincial Park– so stay tuned.
