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.

The trail is paved and crosses the creek here between Eben Park and the Boulder Creek trail. You can also use this as a great trailhead from which to access the mountains and canyons just west of here.

The Lagerman Agricultural Preserve and Reservoir is a small nature preserve that birders, boaters, picnickers, bikers, runners, and dog-walkers can all enjoy. You get great views of the foothills over farms and fields as you ride down well-graded crushed gravel and dirt roads.
