Rabaul caldera is a large volcanic depression formed by a massive eruption, now home to several active volcanoes including Tavurvur. Visitors can hike to viewpoints overlooking the steaming vents and ash-covered slopes, witnessing ongoing volcanic activity. The caldera's otherworldly terrain, with its stark contrasts of gray ash and lush tropical growth, makes it a unique geological attraction. Boat trips across the flooded caldera provide close-up views of volcanic cones and hot springs.
