Fiesta de San Juan in Tenerife

Hey,

we are currently in Tenerife and as I read, there are some really interesting local traditions regarding this day. I know about the goat bathing in Puerto de la Cruz (location, time?) but am interested to see more. Could any local please give us some tips and advices where to go and what to do? We are more interested in witnessing the traditions and culture rather than partying but anything goes. Thanks a lot!
