UPDATE: We are changing the week #1 climb to Exshaw Mountain. Grassi Knob crosses a permanent Wildlife corridor closure where it branches off of the Highline trail. As a result, this trail "illegally" crosses that closure even though it is hiked hundreds of times a week.
Week #1 - The Appetizer
Getting to the start: Park at the Prospector Parking Lot by the Exshaw Community Centre. From there, run to the start of Lower Prospector. The segment starts at the trailhead at the end of Fortress Mountain Way and heads up Lower Prospector.
The Challenge
This of this one as an appetizer to prepare for more serious adventures over the next few weeks. The trail is easy to moderate, and while you're there, might as well make it a 10 km loop for a great after-work outing. From the trailhead at the end of Fortress Mountain Way, follow the trail up for a few minutes until you hit a main junction. At this point, Prospector heads left, Exshaw Mountain heads right. Turn right on the Exshaw Mountain trail. Follow the trail up Exshaw Mountain and hike/run up the open slopes towards the summit. The segment finishes at the big cairn with the summit register box just shy of the true summit.
Getting back down: Two options are available. From the summit cairn, you can either come back down the way you came up. You can also keep following Exshaw Ridge for a km or so and make it a loop. At around 3 km from the start, turn left on a descent and follow the switchbacks back down to Prospector. Follow Prospector back down to Exshaw. This loop is approximately 7 km long.
