We were cruising on a motorboat along the coast of Marinduque when our operator suggested we go to one of the Tres Reyes Islands. It was another 30 minutes from Gasan so we fueled up and took off. None of us had been there so we weren't expecting anything other than to say been there, done that. To our surprise, the water along the first islet was so clear that we could see the beautiful corals below, including brightly colored starfishes, shells, etc. Luckily, we had snorkels and ended up spending several hours enjoying our time... what a find!
