Esther Clark Nature Preserve is a small, undeveloped nature reserve of grassland and oaks. It has no picnic tables, restrooms, or other amenities. It is a good place for quiet meditation or watching the sun set.
Clark Preserve is named for Dr. Esther Clark, one of the founding members of the Palo Alto Medical Clinic. A graduate of Stanford and Stanford Medical School, she was also the founder of the Children's Health Council.
Dr. Clark sold the land for Clark Preserve to the city of Palo Alto on the condition that it be preserved as an open space. For details on park history, see the Palo Alto Historical Association chapter on Esther Clark Park.
