A guide from FaFa Island would take us, on a daily basis, to a different island to snorkel. On three different days, we went to three completely different sites. NO ONE else was at these places--our guide would just anchor the boat, fall asleep, and let us snorkel as long as we wanted. We'd bring lunch and make a day of it. Rays and their progeny, remora trying to attach themselves to my thigh, puffer fish, spectacularly colored sea slugs, octopus, turtles, etc.
