The chances of witnessing a volcano eruption during the recommended time to visit Hawaii (April to June and September to November) are relatively low. However, Hawaii Volcanoes National Park on the Big Island offers an opportunity to explore and witness the volcanic landscapes up close. While the most recent eruption of Kīlauea volcano occurred in 2018, the park provides visitors with a chance to see the aftermath and learn about the volcanic activity. It’s essential to check the latest updates from the National Park Service to ensure the park is safe and accessible during your visit.
