An excellent outing and send-off hike for our buddy Sheldon. Having thoroughly enjoyed our trip up Noseeum Peak in July, Bri and I had it on radar to explore more of the Mosquito Creek area… though given the area’s name opted to save that return for late August. After doing both Mount Bell and Abbott Ridge back-to-back the previous week, we wanted a “chiller” objective that could be completed within 8 hours or less. Mosquito Mountain fit the bill perfectly. Despite its namesake, we did not encounter a single mossie that day, a pleasant relief given Golden’s heinous mosquito season that summer. We had a fit crew of five that day and even at leisurely pace managed a 7.5 hour car-to-car round trip time. We followed the route described in Andrew Nugara’s (2017) More Scrambles, though only ventured as far as the main summit and did not do the extra traverse. It is a very straightforward ascent and would be an appropriate outing for novice scramblers.
Joined by Sheldon, Peter, and James, we started out from the Mosquito Creek front country campground at 7:40am. Sheldon and Peter had both adventured with us before and were keen to join us again, James was new to us but was eager for the adventure. We followed a well-maintained Parks trail along Mosquito Creek to a backcountry campsite of the same name. From the campground we found the side trail mentioned in More Scrambles which leads across a smaller creek into the forest uphill, loosely travelling northeast.
While the foot path itself was hard to spot, the break in the trees was relatively easy to follow through (minor route finding for inexperienced parties) as we were simply aiming to gain the lower west shoulder of Mosquito Mountain. I seem to recall at least a few cairns in the forest section, more so towards the top of tree line where we encountered a rubbly slope. A brief easy scramble up the slope took us to our first direct view of the route along Mosquito Mountain’s long western ridge. It had taken us just shy of 2 hours from the trailhead to gain the clearing.
From ascending that lower shoulder of the mountain, it would take our crew another 2 hours to reach the summit. The remainder of the route was super straightforward following the natural rise of the ridgeline and little more than a scenic hike. Just over half way to the summit a brief downhill section presented itself. If tackled directly this would be a moderate scramble. We noticed some mellower stair-case-like rock 20-30m to our right (south) down the slope and opted for the easy detour. The further down the slope you detour the easier the terrain gets, so we split up and scrambled down at various points, all of which were easy scrambling.
Past this midway point scramble, it was scenic trek to complete the ascent. The route overall appears longer than it is, the opposite of foreshortening, or at least that’s how our crew felt about the day. Once summited we enjoyed a prolonged visit knowing it would be Sheldon’s last Canadian Rockies peak for a long while. Bri and I observed nearby Mount Willingdon and Cataract Peak, contenders for our 2026 scrambling list. A pleasant return along the same ridge, James and Peter opted to scramble up the midway point “crux”. Otherwise a chill and uneventful hike back to the highway. Couldn’t ask for a better day!
