7 miles SE of Ponce is this small island which is a nature reserve and surrounded by the clearest of turquoise seas. The island is crowned by a lighthouse which we hiked up to see - despite it still being operational, sadly it was very delapidated when we got there, a shame seeing as it date back fin Island)to 1887.
Back in the 1800s the island was used as the meeting place for Masons - an organisation that was outlawed at that time, On the hike up to the lighthouse there was a memorial monument to the Masons dating from that time.
