Prepare in Morgan Hill, then let Henry Coe feel remote.

Northern California’s largest state park begins with a demanding final road and opens into rugged Diablo Range country. Pick an entrance and a modest trail before leaving the valley.

How to spend the day

  1. 01
    Select

    Use the Coe Ranch entrance for a first visit

    The park has multiple entrances with different access and seasonal rules. The visitor center at Coe Ranch is the clearest starting point for orientation.

  2. 02
    Prepare

    Stop in Morgan Hill for supplies

    Water, food and fuel are easier to solve in town. The final 13-mile approach is not the place to discover a missing essential.

  3. 03
    Hike

    Choose distance by heat and elevation

    Rugged terrain makes mileage deceptive. A shorter loop with time to rest is a better first visit than a distant objective chosen from a flat map.

  4. 04
    Return

    Leave a daylight buffer

    The narrow park road deserves attention after the hike. Set a return time before fatigue and sunset make the descent harder.

Fuel strategy

Morgan Hill is the last sensible fuel stop

Compare San Jose corridor prices with Morgan Hill before turning onto East Dunne Avenue. The park is 13 miles east of town and the final road adds climbing. A comfortable reserve matters more here than chasing one more cent per gallon.
