Things to keep in mind during your snorkeling trip

Take note of the rich marine life

Plan ahead to make the most of your snorkeling adventure

  1. Underwater visibility is best during low tide, so make sure you check the tides before setting out
  2. Beware of the bura — the famed Adriatic north wind that brings cool temperatures, strong currents, and lower visibility
  3. The best time to go snorkeling is from May – October, when  the sea temperatures range from 20-25° C. Of course, you can technically go year-round–you’ll want to bring your wetsuit if you book your trip during colder months.
