FATMAP difficulty grade
This route you can go in either direction.
I prefer to head to three aisle lake and head that way.
The trail starts off nice and wide and progresses to a nice soft BC trail.
As you start to climb up you get into the AB rock and it becomes more strenuous.
It is very straight forward until your in the valley bottom and have to climb to the ridge.
It is a steep slope to climb and lots of awkward rocks to traverse over.
Once on the ridge this is where you can move slower and carefully as you need to choose your footing and route accordingly.
The time spent up high on this ridge is not long and then you are descending into Astor lake.
You will cross a big snow section you can cross to the trail.
Then it is a similar route from the start and leads you back to the main trail. *there is water on the route in numerous spots
