This is the intersection of the Saint Vrain Greenway and Left Hand Creek Trail Trailhead. The Left Hand Creek Trail will take you all the way into Boulder, so it is a great way to go from Union Reservoir into the city.

The Lagerman Agricultural Preserve has about 7 miles of singletrack that takes you through the nature preserve. The route around the large reservoir is one of the more popular trails in the park.

Great viewpoint along the LOBO Regional Trail. There is a bench for you to stop and take a break to enjoy the vistas.

Though the mud after days of sunshine after winter storm became smooth and look nice. However, there are still cars going through and the washboards could be so bumpy. Especially, the wind speed was averaged around 15mph on that day. It might be hard to write this part.
