The description of this hike (done on 6/21/19) is a combination of the Rock Creek trail and the Gore Range trail to Boulder Lake. Reaching the right trailhead can be confusing and can add unnecessary mileage to the hike. As you travel on the nice (but unpaved part) of County Road 1350 you get to what looks like the parking spot to the trailhead but you can actually continue for another 1.5 miles or so on a rougher but passable dirt road to reach the actual Rock Creek trailhead. The trail starts on an even rougher road and then it reaches an intersection with the Gore Range trail. At this point, you turn right (north, north/west) on the Gore Range trail and follow that to take a left (west) on the intersection with the Boulder Creek trail to Boulder Lake. I uploaded a GPX file for the hike. Most the hike is on the Gore Range trail, a well used, wooded and wet trail. It also had a lot of trees down on the trail and although I went over or under them it got annoying after a while. The destination is really nice but it was a little windy and threatening to storm on the day I was there so I did not linger much. I clocked the length at 5.7 miles with an up and down elevation change of 1208 and 1164 ft, respectively starting at 9455 ft. It took me about 3 h and 30 min with only a 15 min break at the lake.
