I'm not sure if there is nightlife in Pescadero. You'd have to ask a local to find out about that. Unless you want to take a night stroll on the beach I would suggest heading to La Honda for a beer at Applejacks. You could also head north to Half Moon Bay or south (the better choice) to Santa Cruz.

Its a city, I know its not in Pescadero, but its nice to drive to the city for fun, and then return to Pescadero, where you feel safe!
