The road to the summit is totally unpaved and very eroded. It’s an old mining road. The summit offers superb views. It’s definitely worth it. You’ll enjoy delightful views ranging from nearby neighbors in the Mosquito Gulch basin out to numerous Continental Divide summits and beyond. It’s one of the highest mountain roads of Colorado.
Located north of Mosquito Pass, in the Mosquito Range of the Rocky Mountains, accessibility is largely limited to the summer season. It is not generally snow-free until late June or even July in some years. This range is always windy so dress for it. The old mining road is very steep. Starting from Mosquito Pass, the ascent is 2.95 km (1.83 mi) long. Over this distance, the elevation gain is 139 meters. The average gradient is 4.71%.

According to the information provided by, 'there’s an old mining road to the summit that I believe is gated off from vehicles. Regardless, they are very eroded and wouldn't be safe for driving anyways, and I don't believe they go up to the summit at all. There is some old equipment up there. And we did see evidence that someone had driven (or tried to drive) up there at one time. It was really far away so I didn't get a picture but a vehicle had rolled off one of the eroded roads a few hundred feet down the slope. I'm not sure if they gated the road after that happened or if that person came in from a different way, but it didn't look like a good time. You could easily hike either to the summit of Mosquito Peak or to the mine equipment from Mosquito Pass, however. It's not very far and shouldn't be terribly difficult, except for the altitude'.
