It costs between $55-$65 per person (December 2010 prices) for half and full day trips and Capt Russell does not charge for toddlers. The trip sails out of Marina del Mar.  Snorkeling is an option but currently you have to bring your own equipment.  You should also bring snacks if you want some, but soft drinks and water are provided.  Overnighters and week long excursions are an option.  Capt. Russell teaches sailing.
