The Acalanes Ridge Open Space is an area of natural countryside in Walnut Creek, California. There is very limited parking for vehicles available. This natural area constitutes over two hundred acres of open ground which is hilly in most parts. Geographically located between the towns of Walnut Creek and Lafayette, it is intersected by over four miles of hiking trails. Hiking the ridge offers spectacular views of the surrounding landscape.
The ground coverage is mostly grass, bushes, and trees. The trails are compressed dirt. During the summer months, the grass can be long and very dried out. The trails can be muddy and slippery underfoot after rain. Pet owners are requested to ensure that they and their dogs respect all wildlife encountered on the ridge. All dogs using the facility must be correctly licensed by the local authorities, have their vaccinations current and be displaying the appropriate tag on their collar.
Acalanes Ridge Open Space does not have a specific off-leash area for dogs. Park rangers recommend that dogs should be kept on their leashes at all times. Dogs are allowed to be exercised off-leash but if they are unleashed, they must be under the full control of their owners. Unleashed dogs must be able to respond to sight and sound commands instantly even when encountering any distractions.
There are no facilities in the Acalanes Ridge Open Space. Pet owners must ensure they have sufficient fresh water for themselves and their dogs before entering the zone. They are also obliged to provide their own supply of poop bags and collect all faeces produced by their dog. Used bags must be removed from the park zone on leaving.
Pet owners should be aware that the Acalanes Ridge Open Space is a natural zone and is inhabited by coyotes, mountain lions and raptors. Handlers exercising small breeds should be especially vigilant if their pets are off-leash.
