Mill Valley Park Checklist

  • SPF 50+ sunscreen and bug spray — parks like China Camp State Park see active mosquitoes and wood ticks May through October. Reapply sunscreen every 90 minutes.
  • One water bottle per person — drinking fountains exist at most Mill Valley parks but occasionally go offline for maintenance. Pack heat-stable snacks: grapes, apples, trail mix hold up better than chocolate in summer heat.
