Grundy Lake Provincial Park

Grundy Lake is an awesome park - in our top 5 likely. We were lucky enough to camp there in August when there are few bugs, and warm water. It was also just after the forest fire was under control (Parry Sound 2018) and the park had been closed for a while. When we were there the park was likely only 25% full so it was very quiet and there was lots of space available. Overall though the sites over decent privacy and there are composting toilets a-plenty. The beaches are wonderful sand, with brown tannin water, but there are also many spots where rocks provide great jumping locations, or even some sliding slopes.
The trails are interesting as well. There are only 3 and two are not very long, but they are very beautiful. There are lots of spots to sit for a bit and admire the lakes, or dip your toes in the water. The rocks and trees of the Canadian shield is definitely a highlight of this area. There were no trail maps in any of the trail entrances though so we didn't get to enjoy the 'points of interest' as much as we could have.

This isn't a large park but it's big enough that bikes would help you explore the various camp areas and reach all the trails and beaches (8 beaches?). A canoe would also be great to help you explore some of the lakes and other swimming areas they would bring. There are a few back country sites as well that would be nice to canoe into. Canoes can be rented from the Grundy Supply store just outside the gates if you need them (or anything else.) Fishing is big here, and 'Learn to Fish' programs were regular events when we were there. There is not much else around the park, so this is a self-contained little gem of a place just off Hwy 69.
