You push off before sunrise from the western Java coastline, the pier shrinking behind you as the sea opens and the wind picks up. Waves clip the hull, gulls shadow the bow, and the low cone of Krakatau appears as a dark shape against brightening sky — a raw, restless presence that dares you closer.

History
The 1883 Krakatoa eruption was one of the most violent in recorded history, collapsing much of the original island and creating the Sunda Strait’s current topography; Anak Krakatau emerged decades later as a new volcanic cone.
Conservation
Krakatoa sits within a sensitive marine and coastal zone; visitors should follow park rules, avoid disturbing nesting birds, and pack out all waste to limit erosion and pollution.

Prepare for seasickness
Crossings can be choppy; take anti-nausea medication ahead of departure and sit mid-boat where motion is least pronounced.
Sun and salt protection
Bring a wide-brim hat, SPF 30+ sunscreen, and sunglasses — reflected sun off sea and ash makes exposure intense.
Sturdy footwear for landings
Be ready for loose volcanic gravel and uneven slopes by wearing closed, grippy shoes rather than sandals.
Early start for calmer seas
Book the earliest departure available—morning crossings are generally smoother and offer better photography light.
Sea-sickness medication
Reduces nausea during potentially rough crossings in the Sunda Strait.
Closed, grippy shoes
Protects your feet on loose volcanic gravel and slippery rocks during landings.
Sun protection (hat, sunscreen, sunglasses)
Blocks intense UV reflected off the sea and volcanic surfaces.

Light waterproof jacket
Wind and spray on the open boat can be cool; a packable shell helps during wet conditions.
