Just to settle your mind, while the San Luis Light is on leasted land of PG&E's, the nuclear plant is around 7 miles north of the lighthouse.
It is not open each day, they are hiking tours each weekend. The number to call for more information is 805-541-TREK. And if your interested in visiting Piedras Blancas Point light in San Simeon the number there is 888-804-8608.
In the matter of San Luis Light, on the third Saturday of each month a work party will be at the light. They have a small gift dept. setup for the hikers that hike on that Sat.
Hope this helps you out.
