There are many trails there. My suggestion would be to search the database under Clear Creek and Gilpin county. Click above on

There is a nice loop from Idaho Springs to Georgetown. Not really a hard trail, but fun.
Also there are tow books that I find useful. Colorados Guide to back country road (?) by Charles Wells and 4WD Adventures.
Keep in mind that some of the higher elevation trails in this area are probably still snowed in.
