We walk this park pretty much every day with our chocolate lab Dug. He loves to jump and splash in the nearby creek. It's up the hill a bit, not down by the water. Best access is to come in from the East. It's on the East side of the ravine which leads down to the creek. It's likely you'll find it a little NE of the published coordinates.
