In Search of a Secret Beach and Sea Cave in Northern California

Can you reach the hidden crater at Limantour Beach in Point Reyes National Park? This secret sea cave is only accessible at low tide, and we hiked three miles along the beach to find out.
In this episode of Silicon Valley Front Row, host Steve Ispas meets fellow hikers in the parking lot, learns the story behind the collapsed sea cave, and races the clock across soft sand, a creek, and a river flowing into the ocean. Along the way we explore rock tunnels, a sea cave, and one of the biggest mussel beds we've ever seen.
The tide had other plans. Find out how close we got, what the crater looks like from the edge, and what happened to our hiking boots.
Watch the full episode for a Bay Area adventure that doesn't go quite as planned.
