One of the best provincial parks in Ontario on the basis of the site, facilities and the available trails and hikes.
Came here with friends - did a little bit of the back trails to lumsden lake (beautiful, serene, quiet lake and not too crowded).
Also completed the crack the day before (tiring, hard hike closer to lookout point, but well worth the view)
The campsite was amazing, you had enough space, camp not too crowded and facilities were great. Killarney lake at sunset and night was beautiful.
We did 2 trails:
The Crack - 3hrs roundtrip hike + views, hard hike closer to lookout, beautiful views.
Lumsden Lake - 2 hrs round trip + chilling at lake, easy hike (little scary as back country - preferably have bearspray/whistle) - lake was beautiful and place quiet
Definitely one of the better provincial parks in regards to its hikes and camping experience.
