Sugarloaf Mountain Road is a beautiful dirt road that offers great views and is close to Boulder. We got to Sugarloaf Mountain Road from Switzerland Trail and Gordon Gulch its a fun group of trails to run together.
There are several nice offshoots which will likely need to put your Range Rover into low range for. At the end of Sugarloaf Mountain Road you can run Pennsylvania Gulch but if your in a Rover your car is just going to be scratched up with tons of trees whereas sugarloaf mountain does not offer that drama.
We then drove down on roads and took a hike on the Boulder Canyon Trail
