What to expect on NCAR Hill loop from National Center for Atmospheric Research
The NCAR Hill loop offers a diverse cycling experience, starting with the challenging, entirely paved NCAR Hill climb itself, known for its sustained incline averaging around 5.9% over 1.6 to 2.4 miles. As you ascend, you'll be treated to breathtaking panoramic views of the Flatirons, Boulder Valley, and the unique architecture of the NCAR building. While the main climb is paved, longer loops incorporating this section can include gravel and dirt paths, as well as city streets, so a robust road bike with suitable gearing or a gravel bike is recommended. This route is perfect for those who enjoy a demanding ascent rewarded by expansive vistas.
Planning your visit
The NCAR Hill is a popular spot, especially in winter, due to its sun exposure which often keeps it dry and clear of snow when other areas might be impassable. The road leading to the NCAR laboratory is a dead-end, ensuring minimal traffic, which is a huge plus for cyclists. It also serves as a trailhead for numerous other open space trails, allowing you to extend your ride if you wish.
