Secret Beach is a very small beach located on a trail just south of Spruce Island Viewpoint and north of Thunder Rock Cove. There are two theories as to how this beach got its name. One is that there is not an official parking lot or designation. The other is that the furthest of the three beaches is only accessible during exceptionally low tides and was visited by only a few people each year. The first beach is accessible at any tide. Follow the path down to the parking area, then there is a steep and somewhat challenging climb down a rock, across a small stream to a beach. At low tide, it is possible to head south to a second beach. At a very low tide (-2 ft) there is a tunnel that is open to walk to the second beach. Also, at a low tide, there is a short cave to walk further south to a third beach, which is actually the beach below Thunder Rock Cove. Thunder Rock Cove is a little visited parking area north of Brookings because little is visible from the lot. However, be certain to take the hiking loop out to view the rocks out to Thunder Cove. This section offers some of the most spectacular views that visitors rarely see who do not venture far from their cars. Those who take the short hike are rewarded with views of crashing waves, tiny beaches and inlets as well as a collection of marine birds. The well maintained trail gets right up to the edge, so be certain to watch the children and pets. The trail is a portion of the Pacific Coast Trail. There are two parking lots used to access the beach. The shortest hike is from a small unmarked parking lot between the Spruce Island and Thunder Cove parking lots. Turn off just before a guardrail. Others park at the Thunder Cove parking lot and take the trail to the north. This is a bit longer hike, but the parking lot is easier to find and access.
