We took advantage of the $20 midnight bathing deal at Esalen. If you make a reservation, you can make use of all of their tubs (wonderful geothermal tubs overlooking the ocean and open to the sky) for $20 between 1am and 3am. Being natural night owls, we took advantage of this.
The next morning we hiked to the beach at Andrew Molera State Park.
