Clear Lake in San Juan County, Colorado, is a pristine example of a high (above tree line) lake in the bowl of a glacially-carved basin—I traveled there this morning. The lake is natural and is reached by traveling up San Juan CR 12 from Point A shown on the GPS map below. To get there, travel west from Silverton on US Hwy 550, then taking the Mineral Creek turnoff to the west, which is CR 7. At 3.9 miles in (Point A), you’ll see the cutoff quite clearly as shown below.
And here’s a closeup of the sign you can just make out in the photo above. (And, to the right of where the sign is, on the right side of the road, is the San Juan CR 12 sign.)
There are several Forest Service campgrounds along CR 7. You can access these in any vehicle. Going up CR 12 is another story. An Explorer or Blazer can make it most of the way up and you can hike the last half mile or so (but remember, you’re at almost 12,000 feet above sea level, so plan accordingly).
If you want to travel all the way to Clear Lake itself, you’ll probably want a high clearance 4WD, an ATV, or a dirt-bike motorcycle. I took the latter. The road up the last couple switchbacks gets suddenly rougher with more exposed rocks, not a hospitable place for lower-clearance vehicles. There’s some scree, too.
As you get there, you’ll find a lower lake, much smaller. It appears not to have a name, so I’ll call it “You’re Not There Yet Lake.” Keep on going and you’ll find the lake. The view below is taken from Clear Lake’s outlet looking back across the lake.
The wildflowers are amazing—so many that I put them in another post.
There’s a small parking area with ample room to turn around. Note that there’s a side road (shown as Point B on the GPS map below). I DO NOT recommend using this road with anything other than a motorcycle or a very competent ATV (or on foot) because there really isn’t anywhere to turn around. However, it does provide a spectacular view of the lake itself—that’s where I took the photograph at the top of this post.
Heading back down CR 12, you have a nice view showing just how steep the last part of the road is. I had no trouble going down. Although there’s some scree, I took my time, then got past the first few switchbacks. After that the road gets much easier.
Once down on San Juan CR 7, you can continue southwest for several miles to the trailhead for the five-mile trail that goes up over the divide and down into Rico.
The GPS map showing how to get to Clear Lake is below. The intersection of CR 7 with US Hwy 550 is at approximately N37° 49.1′ by W107° 42.15′. The distance from the intersection of CR 7 and Hwy 550 to point A is 3.9 miles. Point A is the intersection of San Juan County Roads 7 and 12. From Point A to Clear Lake via CR 12 is approximately 4.6 miles. From Point A to the Trailhead to Rico is 3.3 miles.
