The road that leads to the cache has been closed due to a landslide. Despite this there is still access to the cache. Follow the perimeter road to the orange netting near the landslide area, just to the left/east side of it there is a small trail that connects with the road to the beach. Please use caution and avoid the landslide area. I recommend parking your bike at the top of the trail. The cache is now an Ammo Can, which should prevent the raccoons from chewing it up. There is room for TBs and trade items.
Once you are done finding the cache walk down the stairs to check out the beach, it has a really nice view of San Francisco and the Golden Gate Bridge.
