Off to snorkel on a catamaran in the city of Fajardo, which is about an hour east of San Juan... We discovered that some of the roads - even the major ones - are not very well marked in Puerto Rico, so we were glad we had budgeted an extra 30 minutes or so to get there. We went out with East Island Excursions on their power cat The Island Flier. I was so glad the sailing cat had been booked that day, since there was no shaded spots aboard. The Island Flier had a shaded cabin - which was a very good thing after the sunburns from the day before. (For some reason the kids wanted nothing to do with my SPF 50 sunblock, choosing to fry instead.)
We were suppose to go to Culebra, but the winds weren't favorable, so they took $20.00 off each ticket and we snorkeled / swam at three different spots instead: Icacos Key, Palominos Key, and Palominitos Key, though some maps refer to them as Isla Icacos, etc. The $20.00 off really added up since there were seven of us. Best of all, the kids were thrilled to go swimming at different spots.
It was a spectacular day, despite the second layer of sunburn. If you are headed to Puerto Rico and you want to snorkel, I would recommend East Island Excursions. We were very pleased with them.
