Set out from Carita for a full-day boat expedition to Krakatoa, where sea travel and a short volcanic scramble reveal one of Indonesia's most dramatic geological stories. This guided trip pairs maritime crossing with on-island observation and practical safety briefings.

A low, brassy sun lifts off the Sunda Strait as a charter slips away from Carita, engines humming and spray cutting the air. Within an hour the Java shoreline thins, then disappears; the sea becomes the only route to the scarred cone that still commands the horizon. On a one-day expedition to Krakatoa, the voyage is as much part of the story as the island: waves push, gulls wheel, and the volcano waits with a crater that has remade itself more than once.

Prepare for seasickness
Take anti-nausea medication before boarding and sit mid-boat where motion is least pronounced.
Sun and wind protection
Bring a wide-brim hat, SPF 30+ sunscreen and sunglasses—the exposed deck intensifies UV and wind chill.
Wear sturdy shoes
Use closed-toe shoes with good grip for walking on loose ash and jagged volcanic rock.
Follow your guide
Obey exclusion zones and stay with the group; volcanic terrain can be unstable and gas levels change quickly.
Closed-toe hiking shoes
Protect feet from sharp volcanic rock and provide traction on loose ash.
