Though not the most impressive caves on an island famed for its immense underground system of limestone caverns, the Cuevas del Ham - or Caves of Hams - are nonetheless a popular stop for multi-destination guided day trips. Built along an underground river called the Sea of Venice, they are most notable for their spiral and hook-shaped "stalactites," very different from those seen in most other Mallorca caves.
The tour takes about 45 minutes, and includes a softly lit medley of Mozart tunes, played on the slowly flowing sea.
