The relatively short Acalanes Trail is the southernmost trail in the Acalanes Ridge Open Space. It leads over grassy hills, overlooks the city of Walnut Creek and provides vistas over the whole area

You'll encounter a steep incline as you begin to ride this trail along the Acalanes Ridge Open Space. However, the payoff is worth it as you are greeted by a stunning panoramic vista of the picturesque Walnut Creek and Lafayette area.

Larkey Park, right next to the Lindsay Wildlife Museum, has big grassy fields and tall trees providing plenty of shade, with picnic tables, restrooms, and a playground. The Briones to Mount Diablo Trail runs right through the park with connections to the Acalanes Ridge and the backside of Briones Regional Park, along with a few other local walking trails that connect here, making it a great base to park and satellite out to explore the surrounding areas.
