The Fortress

Route Description for The Fortress

The Fortress can be ascended via either the Headwall Lakes or Chester Lake trails; we chose to ascend via Headwall Lakes and descend via Chester Lake. This loop option is only marginally longer than a direct in-out ascent via Chester Lake (the shorter direction) and would allow us to avoid the hordes at Chester Lake for half the trip as well as provide a bit of scenic variety.

We started hiking on the Headwall Lakes trail around 8:30 am, making quick work of the first 3.0 km or so of trail that follows a snowshoe route/road that runs nearly parallel to the Spray Lakes Road until it reaches Headwall Creek. We crossed the creek on a new bridge, then after a short ascent on the snowshoe trail/road, picked up the good trail heading up Headwall Creek. It’s marked by two cairns, flagging, and a trail camera, and the snowshoe trail/road has a line of rocks across it to discourage zombie hikers from going too far.

The trail was in very good shape and any area that had been affected by the 2013 flood was well cairned, although these sections were so short that cairns weren’t really necessary. We had been expecting greater damage and route finding difficulties since we had heard of a few groups getting lost on the trail, but the trail was about as obvious as possible without being a veritable highway like the path to Chester Lake.

We reached the lakes after about two hours of easy hiking, then continued to the base of the Headwall-Chester col to have a snack in the sun; the Headwall Lakes valley had been entirely shaded and subsequently cool as we’d passed through. After lunch we started up the rubble to the col, which we reached in just 30 minutes. The rubble is not fairly easy as far as rubble goes!

From the col it was an easy plod to the base of the summit block where we had to scramble up a 3 m cliff band to reach the summit. The scramble was mildly awkward as the boulders just weren’t in the right places! The view from the top was spectacular, and while it was smoky, it wasn’t as bad as it has been for much of the 2018 summer.

Despite a gusty wind on the summit we managed to eat lunch behind a small windbreak, then retraced our route back down to the col. Depending on the time of year, the descent down the Chester Lake side of the col will have you in soft, almost sandy, scree nearly the entire way down to valley bottom, or hard-packed mud with short sections of chunky scree! This time it was the latter and the descent was quite miserable, actually, and the kilometer of rock and boulder hopping through the valley bottom to reach nicer trail was equally annoying.

We reached Chester Lake and the insane weekend crowds about an hour after departing the col, then quickly made our way down the trail and past dozens of others to the car. It was an easy and scenic way to spend the day!
