The Pineridge Natural Area is a family friendly park, bike trail, and playground that is easily bike accessible from Fort Collins’ hard surface multi-use path named West Spring Creek Trail. Specifically, it is located in the southwest corner of Fort Collins. My wife and daughter (aboard baby bike seat) were able to ride most of the soft surface gravel paths but it was little risky. In addition, my daughter enjoyed the nearby playground. Finally, there is a mountain bike skills park located off of the West Spring Creek Trail near the playground.

As you can see from the following picture, the bike trail is pretty smooth both in the foreground and the background. For more information on mountain biking in Pineridge Natural area, check out Fort Collins Foothills Trails.
