January is a prime time for whale watching - recommend going sailing on a catamaran at least twice. On your drive up the pacific coast to Todos Santos, stop at Km 69 a little place called Art & Beer - google it. Also along that drive, a surfers beach called Los Cerritos. There's a couple of newer places there on the beach so it's no longer just surfers - but waves get big there in the winter and a lot of surfers come to ride big waves.
