Mosquito Creek Road is a fun trail that is less popular than other trails in the expansive Yankee Hill trail system. It is one of the many ways to access other trails in the area, and it offers beautiful views of aspens in the fall, colorful wildflowers when they are blooming, and panoramic views of the mountains in the distance when you reach the north trailhead. There are many mining claims along the trail, some still active. The trail cuts through private property, so do not leave the trail!
Intersection of Apex Valley Road going north-northeast/south and NFSR 705.1/Mosquito Creek Road going north.
Turn north to begin the trail.
There are Private Property and No Trespassing signs at the beginning of the trail. This trail goes through private property which is on both sides of the trail, stay on the trail.
Apex Valley Road is a residential street. Please stay under the posted speed limit to respect the residents that live directly off of the road.
Follow Colorado Hwy 119 out of Black Hawk and turn south onto Apex Valley Road. Proceed 3.9 miles on Apex Valley Road and the trailhead is on your left. If assembling a group, it would be best to meet at a gas station and convoy in, however Apex Valley Road is a wide dirt road, and where it meets with Colorado Hwy 119 is a large dirt area.
Follow Colorado Hwy 119 out of Black Hawk and turn south onto Apex Valley Road. Proceed 5.5 miles on Apex Valley Road, and make a left to go west on County Road 4-N. Continue on County Road 4-N for 2.1 miles and the trailhead is on your left to the south. If assembling a group, there is a parking area just west of the trailhead.
Land Use Issues

This will keep our trails open for present and future generations to enjoy.
Only ran the trail from waypoints 1 to 2 and turned off. It is passable for that far, but the snow is getting deep. Don't let all the "private property" signs scare you away. The road is perfectly legal and the local land owners are trying to keep people from traveling a public route.
Trickier than advertised with long sections of steep, loose rock with average sizes around 4". Tires sank 1-3" in the rock, making large obstacles worse than they appear. We ran it downhill, which likely made this worse. Multiple sections with pinstripping. Otherwise beautiful and quiet. Several locals out walking the road yelled at us for being on the trail. I showed them the MVUM but they still insisted they would report my license plate to the police and I should turn around immediately.
Just to be clear: this road was MUCH more technical than the nearby mammoth gulch, which we took to connect, and more difficult (we hit our skid plate on 9" of clearance twice)
that the yellow rated "rollinsville" route we used to connect from Nederland to mammoth gulch.
Coming from Elk Park Road, we attempted to run the trail in the reverse direction of this guide. 50 yards onto the trail, we buried our Jeeps in giant, soft, snow drifts. The beginning of the trail (per this guide) was snow covered and looked doable at least for a short while, but no idea how big the drifts are back deeper in the trees.
We went up Mosquito Creek from Apex Road on January 27, 2018. The weather was mostly sunny but cool and a little windy. We had four rigs along, my lifted XJ, another lifted XJ, a TJ on 35s and a stock JK. The trail was plowed through the private property at the beginning but once we got past the cabins we were breaking fresh tracks through about six to eight inches of dry powder. The higher we went the deeper the snow got until a little over half a mile in we were having enough difficulty that we decided to turn around. The snow was around two feet deep at that point.
We ran Mosquito Creek on October 21, 2017. It was cold and quite windy with frequent, light snow flurries. There was about an inch of accumulation with conditions on the trail being bare ground to occasional drifts up to about six inches. We started from the Elk Park Road trailhead with intention of connecting to Miners Gulch. We were unable to complete the connection due to a large, fallen tree blocking the road just past (south of) Waypoint 3. We did not have chainsaws and cutting through the large tree would have taken hours with the hand saw and axes we had so we turned around. We took the long way around to the other end of Miners Gulch and ran it the opposite direct from what we had planned. After completing Miners Gulch we took the bottom part of Mosquito Creek out to Apex Valley Road without incident.
