We love discovering hidden secrets wherever we live, and San Diego has been full of them, including a secret sea cave and dangerous surf trail named after the famous trail in Vietnam. While hiking the Ho Chi Minh Trail, we discovered yet another San Diego secret: the Mushroom House.

The Abandoned Mushroom House on Blacks Beach San Diego
A unique mushroom-shaped building hides at bottom of the cliffs at Blacks Beach. The architect Dal Nagle designed it and built it in 1968 to withstand naturally occurring rock slides, earthquakes, and waves. The original name was the Pavillion, and you could access it from the cliffs via a nearly vertical tramway running almost 300 feet down the cliff. It was also used as a guest house, and it offers a 180-degree view from Torrey Pines State Park to La Jolla.



It looks mostly empty now but rumors say it was last owned by UCSD as a place for professors and administrators to take a sabbatical. You can’t enter the house since it’s private property, but we enjoyed taking photos and relaxing on the beach.





If you’ve explored the beaches in San Diego, you’ll know that Blacks Beach is also known as the nude beach in San Diego. If you want to go nude, you can find the nude side at the north end of the beach.
