You don’t have to bring along any gear to hit the Los Cabos snorkeling spots. Of course, you can if you want to. However, it’s normal for organized tours to provide everything you need, from the goggles to the breathing tubes and mouth fixtures. They’re also readily available from rentals in most of the popular spots, but will be harder to find in remoter destinations like the Isla del Espiritu Santo. Always check that all snorkeling equipment has been properly disinfected and cleaned before use.
