Leave the ship for a day and follow a river that runs beneath a cliff — the Puerto Princesa Underground River tour pairs a scenic 90-minute drive with a motorized banca ride into one of the Philippines’ most dramatic karst caves. This private shore excursion is timed for cruise passengers and includes park fees and lunch.

You step off the ship into humid air heavy with salt and green — Puerto Princesa’s port is busy but compact, and a local guide waits at the gates with a name card and a calm, practical smile. The ride to Sabang is a slow unwinding: two-lane highway, patches of coconut palms, roadside villages where children wave, and the occasional limestone bluff rising like a ship’s mast. The drive is roughly 90 minutes each way; at Sabang you transfer to a small motorized banca and cruise toward a cliff face that hides a cave mouth as ordinary as any seaside cliff and as extraordinary as anything you’ve seen.
