The path sticks to Sherbrooke Creek for the next 500 m as it meets a 20- to 25-m stepped waterfall. Our group was unaware of the existence of this cascade, so we were ecstatic with our discovery. We stopped and played here for 20 or 30 minutes before continuing our journey. This would turn out to be only the first of many spectacular waterfalls along the way, some almost within arm’s reach, many others visible off in the distance. Another pleasant surprise came a few minutes later in the form of a long meadow on the banks of Sherbrooke Creek. It takes about 15 to 20 minutes to cross the expanse of this meadow filled with red paint brush and a variety of low-growth shrubs.
The path leaves the openness of the meadow for a forest and switchbacks that deliver more waterfalls along the way before meeting an exposed subalpine region of stunted trees and pastures another half-hour upward. There is some minor rockhopping and log walking required to cross the few streams that drain this area. Sticking to the trail for a further kilometre brings you to another small creek crossing at the base of a small, open, grassy meadow with the magnificent Mount Niles straight ahead. Directly across the valley, look for a rather large cairn that marks the start of an uphill battle. The cairn sits at the base of a drainage outlet that is usually dry. Walk up the drainage for about 50 m until you reach a well-defined track on the right. This path is a saviour of lungs, as it switchbacks up the hillside. If you miss this trail, there is no other way but straight up the dry gulch. An hour of hiking brings you to a rolling meadow that eventually hooks up with a scree slope at the base of the summit push. You have hiked 8.8 km from the trailhead.
The way from here is a straightforward jaunt across the base of the scree slope to the far left (west) side of Niles Knoll. The trail has faded, so make your own way across and up, wrapping around the far side. Upon successfully reaching the obvious col, continue on a path that progresses up to the top of the knoll along the summit ridge.
Views from this vantage point are overwhelming as the Wapta Icefield comes into view to the north and Mount Daly to the northeast, while directly south lies the wonderful valley you’ve just hiked up.
Mount Niles history
The mountain was named after William Harmon Niles by Charles S. Thompson in 1898. Niles was one of the first explorers to climb the mountains of the Yoho area. He was a professor of geology at Massachusetts Institute of Technology and served as president of the Appalachian Mountain Club. The first ascent of this wondrous peak was by D. Campbell and C.E. Fay in 1898.
