Of the more than two dozen hiking trails in Cape Breton Highlands National Park, Skyline Trail is consistently rated in the top three. It's often called the "can't miss" hike along the Cabot Trail. Makes sense: it's fairly short, relatively scenic (especially at sunset), is frequented by moose and allows visitors to choose between a 6.5 km (4 mile) out and back or 8.2 km (5.1 mile) loop route. So of course we had to go!
