Ah, a good nice long ride in the Colorado Front Range foothills. If you’re like me, you like your rides to be challenging and engaging – as well as avoiding perils, such as traffic. A ride from Boulder to Idaho Springs (and beyond!) should be an easy target to hit. Idaho Springs makes a good resupply point, if you’re hoping to go further into the mountains, as there’s a good bike route from the Springs that you can take up and over Loveland Pass and onto the other side of the Continental Divide.
Unfortunately, between Boulder and Idaho Springs are the old mining townsites of Black Hawk and Central City, which now are home to gambling towns. Black Hawk seems to have quite an aversion to cycling in general, going so far as banning it outright in town. The reason? Traffic from people coming into town to gamble – one of the only reasons one would come to Black Hawk and stay for any extended period of time. No gambling, no Black Hawk. This ban was overturned by the Colorado Supreme Court, but Black Hawk has made it uncomfortable for cyclists to go through town, as they’ve made an out of the way detour that bicycles need to follow – you can’t use the main street, that goes right to Central City! Thus, cycling is still banned in most of Black Hawk.
I don’t necessarily like going through Black Hawk/Central City. You lose and gain a tremendous amount of elevation to essentially ride through the middle of a high-traffic area (ie:no payoff!)- an area that doesn’t even like you being there. But, if you don’t mind some gravel and a more adventurous route, there are alternatives:
