White Hill is the highest point in Nova Scotia at 532m (1517 feet) and is on the bucket list of any serious Cape Breton hiker. As of 2015, the Lake of Islands based route is still the recommended path to follow. You can reach the Lake of Islands trail head by following the Branch Pond Look-off Trail to the end and keeping on going. To get to White Hill, just before reaching Lake of Islands, turn left onto an old fire road. After 6.5 km turn right onto yet another fire road heading west-northwest. White Hill Lake and White Hill should be visible shortly. At the highest point in the fire road, leave the road and bushwhack 820m through dense growth to get the summit. Retrace route to return.
There is a back country campground at the Lake of Islands to break this into a couple days if desired. Its a long trek for a single day but doable. It is also possible to use the Franey Mountain fire road to get to White Hill, which is shorter, but we have no information on the state of that trail these days.
