I made my way up Mount Fromme on a muggy mid-morning. The entire hike took me six hours, including a long lunch break at the top, and getting lost a few times on the way back down and accidentally tacking on a lake loop, but is likely doable in just over four hours. I didn’t see any other hikers but the trail does intersect with busy mountain biking trails.
The physical trail is not well-marked, and though there are trail markers, they are few and far between. Use your instinct to follow the trail as well as you can and keep your eyes peeled for the pink and orange markers to keep you on the right track. The trail is not difficult, save for some substantially steeper sections, but you will notice there are quite a number of tree roots that are just waiting to trip you up!
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. On a clear day, you can see Grouse, Thunderbird Ridge, Goat Mountain, and Garibaldi off in the distance.
Senate Peak is accessible from Mount Fromme, and is quite well marked until the very end where it becomes unclear. The only indication that you have reached Senate Peak is a little orange tag hammered into the rock. Keep following the loop and you’ll see a lake on the way too, and then you can make your way back down the way you came at the intersection you turned right at to get to the top.
