Mount Fromme is not as frequented as neighbouring trails on Grouse Mountain and in Lynn Valley. The trail has some trail markers, but is not well-trodden. At the top of the root-filled and winding hike, you will have a nice view towards the North Shore mountains and in particular the outlines of Grouse's ski runs.
From the top of St. Georges Avenue, take the trail into the forest and over a wooden bridge to a clearing under powerlines. Turn right under these powerlines, and turn left at the next junction up along the St. Georges Trail past a radio antenna and a small wooden bridge. Make your way up the steep trail, turning left at the first junction and right at the second. Don't get confused with the Baden Powell trail!
Complete the St. Georges Trail at the Old Grouse Mountain Highway and turn left until you reach the junction at the first corner. Take the trail going directly right in the forest, not the wide one leading straight from the road. Head up the trail and cross the Old Highway again into a ditch, using a rope to climb up. The trail will make its way to the right of a gravel pit which you cannot see from the trail unless you leave the trail and peer over the edge, but you can most definitely hear it! Follow the trail up until you reach a well-marked junction, where you take a right until you reach the top.
