Getting to this sign requires a hike through the beautiful redwood forest. In the summer, the Aptos Creek Fire Road is open, allowing access to the Porter Family Picnic Area for parking. From here it is about an hour walk to the site on the Aptos Creek Trail. In the winter time, wet weather may cause the fire road to be closed. Parking is then available at the Emmet Reed Picnic Area near the entrance station. From here it requires an additional hour hike.
The fire road is normally closed to cars starting at the Porter Family Picnic Area. From this point, a half hour walk will take you to the Aptos Creek Trail off the fire road. Another half hour walk on a single track trail with a couple of bridgeless stream crossings will take you to the point of the given coordinates.
The location of the sign is on a cliff above Aptos Creek. Across the creek, another cliff rises hundreds of feet higher. Because of the steep ravine where this sign is located, GPS readings are difficult to obtain. My GPS receiver ran for 10 minutes using waypoint averaging to get the given coordinates! Five satellites were visible and accuracy was still not that great.
