We are leaving for Costa Rica in 10 days and are starting to think about what to bring with us. Is there worth while snorkling around Puerto Viejo or Cahuita? If so where? We are spending 5 nights in PV and 3 in Cahuita and will have a rental car. Should we bring our masks and/or fins? I don't mind renting fins, but masks that leak are not fun in salt water. But if the Snorkling is not worth it, we'll leave masks and fins home and travel a bit lighter. Let me know your thoughts.
