Drive to Manning Park Lodge and turn right. Follow the road until it forks and go right about 3 km's to the Strawberry Flats parking area. Park your car and go to the left down a little hill. A big sign says, Snow Shoe Trail or if you prefer you can walk along the cross country ski trail. If you choose this route, proper etiquette says stay off the cross country skiing tracks and not in the middle of the road. Stay to the side.
Keep walking on the wide road and soon you'll come to fork in the road. Either way it's a Strawberry Flats Road loop. After a short time you'll see a, Three Falls sign on your right. You can go up here or across the ski run. Just stay out of the way. If you choose the Snowshoeing Trail you'll walk in the forest, which is a groomed trail that has beauty at every turn. Keep walking along for 2 km's to the edge of the ski run. To change it up you can go on the way along the road and on the way back through the forest...
Note: It has been reported to me that the trail is a lot skinnier than usual at the Three Falls and BC & Manning Parks are asking people to not SS this trail. However, if you choose to go here please use caution at the last and final falls as slipping could result in serious injury.
To get to Three Falls...Go up the hill and to your left is this side trail, it's un-marked. Now your in the woods as you walk along a skinny trail. Sometimes it pops into the open and sometimes it's back in the trees as you make your way to Shadow Falls at 3.1 km's, your first of three falls. Just a little descent into a lookout and you'll see Shadow Falls far below. This is a perfect spot for a snack or to return later for lunch. Carry on along the trail and soon you'll come to Nepopekum Falls, at 3.2 km, and then descent to Derek Falls, at 4.5 km's. The third of the Three Falls is the prettiest. The trail here is a skinny trail that's open on one side. Not my favorite trail but most wouldn't bat an eye at it. To return back to your car you go back the same way. Happy & safe snowshoeing.
