this is directions from my house approximately. well anyway its in Colorado Head West on 285, then take a right and head North on 470. The first actual street you can exit on called Morrison Rd. turn left and head west up trough Morrison Colorado, and up this curvy road into the mountain. Once your in Evergreen turn right on Evergreen Parkway, and take it until Squaw Pass RD. Turn left here and let the adventure begin ;] For first little while it will be pretty straight, but then it gets really curvy with plenty hairpin turns. It doesn't have guard rails however so try staying in your lain and watch your speed haha. Once you get to Echo Lake / Mt. Evans RD. turn around and have a fun drive/coast down because if you keep going you will end up in Idaho Springs.
:] i love this pass its fun coasting down the mountain because you average 80 or so MPH without any acceleration needed. Also there are hardly any cars that go trough here and in my 20-30 trips up there i have never seen a cop :]
This is a google maps' satellite view of the road:
