Castillo San Felipe del Morro
20-25 min walk from the piers, across the great lawn
Six storeys of Spanish fortress stacked on the harbour mouth, begun 1539, never taken from the sea. The $10 ticket covers both forts for the day. The approach across the vast green esplanade, kites overhead, is one of the Caribbean's great walks.
Must try. Buy a $5 kite from the lawn vendors and join a 400-year-old tradition
$10
