"A little side trip up to the unique rock features on a visit to Hell Holes. Awesome area with some really cool and unique features. I'd recommend a trip here to anyone local. The top of Devil's crown is not on the trail, but it isn't overly difficult to get up to either." - Devil's Crown, UK-Ranger, Jul 28, 2018
"Went with several members of the Brockville Hiking Club to what turned out to be a GREAT area, well worth the $7 entry fee! It may have only been a 3.2km trail, but it was PACKED with amazing sights, and of course the main attraction of the Hell Hole cave." - Devil's Crown, RangersApprentice, Jul 28, 2018
"3rd time up here, and it's stunning every time. An impromptu hike around the Frontenacs to this old favourite. A first for one of our friends, second time for 2 others. We then headed out to Big Clear Lake Lookout. A first time for our 3 companions. " - Salmon Lake Lookout, UK-Ranger, Jun 10, 2018
"A great spontaneous hike with some good friends - Salmon Lake Lookout is always a great place to visit for excellent views that can be reached with just a few hours of hiking." - Salmon Lake Lookout, RangersApprentice, Jun 10, 2018
"We like hiking. It was St. Patricks Day. So it seemed very fitting to go hit some peaks in the Mount St. Patrick mountains! This one was mostly a drive up, with a very short walk to the site where the fire tower used to be." - Kennellys Mountain, RangersApprentice, Mar 17, 2018
